A Note from the President . . .

or more need cleaning and probably half of them I would like to customize, refinish or restore. Some even need mechanical repairs I just haven’t gotten around to. While you have them out, do yourself a HUGE favor and take a couple of digital photos of each one, including the serial numbers, and save it all on a thumb drive to store offsite for security and insurance purposes. Also, create a written list of the make, model, and serial number. Have that stored digitally and print a few hard copies to store in a couple of places. If anything happens, such as a fire, burglary, or any other reason, you will be glad you did. Trust me, I know. You can also take this information and create an appraisal for each firearm, so if you have a loss or God forbid, anything happens to you, your family will know what your guns are worth. The AGI Certified Firearms Appraiser course will help you do that efficiently and provides you with the forms you need to do a professional appraisal. Once you have created a list of projects as you looked at each of your guns, put them in some sort of priority. Then, take the time to order in the parts or supplies you need to do the job. That is what I am doing as I have a number of guns that have broken parts and it would be more efficient for me personally to replace those parts rather than repair or make them. Some of them have been out of operation for several years and I still haven’t gotten around to getting the parts. I am going to do that now, before the parts are no longer available. Having a “Priority List” really helps you focus on what to do next. Like many professionals, Gunsmiths are often in the same position as the “Cobbler’s kids have no shoes”. We are always working on other people’s firearms and don’t put a priority on our own guns. Now that we have some time, let’s get OUR projects done. I am sure that our kids, friends, and family will have gun work that should be done too. Make good use of your forced isolation, but still stay connected. The new Gunsmithing Club of America website is a great place for that to happen. Go check it out at:

www.GunsmithingClubofAmerica.com Best regards, Gene Kelly President AGI and The Gunsmithing Club of America

If you are like me, the response to the COVID-19 pandemic has radically changed much of your lifestyle, including your ability to interact with others the same way you did before. There have also been benefits, including reevaluating what we do on a daily basis, significant changes in how we manage our time, and our personal relationships. Suddenly we either have more time available if we are not working, or if still working, more time because of not having to commute, meetings, and regular sporting or social events. The question is, what are each of us doing with this “newfound” time? Your situation may be like mine, requiring you to work to keep everything moving. I am actually working more hours because I am doing so much from home, where the hours tend to get extended. Of course other things have been cancelled such as business travel plans, family camp, vacations, etc. So, if I manage it correctly, I still have extra time. Some of that time needs to be dedicated to the projects I haven’t gotten done, including my personal Gunsmithing projects. Some of what I am doing includes experimenting with various night vision devices, checking and enhancing my security firearms, building up a new MSR platform and watching some AGI video courses to shortcut my learning curve. I am again going through the Certified AR-15 Courses taught by AGI instructor Mark Foster, including the Law Enforcement Armorer’s Course and the Practi-Cool to Tactical Course. Lots of good information, to say the least!

Here is a suggestion you might want to follow: Pull out your firearms one at a time and make a list of what you would like to do to it, such as clean and maintain, repair, cus-tomize, etc. If you are like me you own a lot of guns. At any given time 10%

Jack’s Corner

By Jack Landis

AGI Technical Services Manager, GCA Connection and GunTech Editor

By the time you read this, assuming you ran out of actual important things to do, two things, at least, will have occurred. 1. Assuming you live in a state with rational government, you will be getting back to work, attending church, and can go get a bite to eat and a brew somewhere other than your own kitchen. 2. The AGI/GCA crowd will have returned from our Range Test week in Nevada. I realize that the second hardly competes with the first in terms of your personal, business, and spiritual lives, but it actually is some of those things to me. Especially since many of our students, members, and, well yeah, instructors fall squarely in the middle of the danger range for the COVID Crud. I hope all of you and your family, friends, and associates are well. On to number two, we’ve actually got our sweaty little hands on the Ruger® Model 57 5.7x28 FN pistol, their PC Charger Pistol, which I didn’t even know existed until they offered to grace me with one, and the Wrangler .22 SA Revolver. I believe the Wrangler is a Single Six with an alloy frame and less expensive finish, but we’ll see. Besides, it is a .22 revolver, what’s more fun than one of those? Remember being out in the woods, fields, local dump, etc. with one and shooting until your box(s) of Shorts ran dry? Remember when Shorts were cheap and your Dad didn’t want to waste money on Long Rifles if they were not going to be used for hunting? That was about as much fun as there was to be had, at least until girls and beer were suddenly invented. Colt’s marketing guy is flogging their shipping people to get us the Python 2020 and the new King Cobra, The lock-down in the Northeast is affecting them too, and the gun and ammunition companies are all going nuts trying to keep up with demand.

I kind of want to compare them as well as look at each as a stand-alone. I’m going to toss my nicely tuned-up S&W Model 65 into the mix as a classic known against the new unknowns. LATE UPDATE: THE PYTHON IS ON THE WAY VIA FED-EX. I have a SIG Compact grip frame, as well as the Wilson Combat, and brand new Polymer80 flavors to test drive on my own SIG P320 Carry pistol. It also sports an Apex Tactical Forward Set trigger which we’ll test against the stock trigger and Mark Foster’s P320 with the Apex trigger and his own trigger work combined. Should be fun.

We will shoot Mz. Lenée’s Glock 17 with the Rock Island .22 TCM 9R barrel for reliability and accuracy, now that I believe I’ve corrected its original issues. We’re going use my Glock 22 to test the Pressure Break Glock trigger Gene was so impressed with in last month’s issue, and we have one of the Lightning Tap double strike capable Glock triggers on order, but it is unlikely to arrive on time. The virus again, sigh. Unless Mr. K adds something else to the mix, we’ll finish by comparing my Zastava M57 and his Tokarev TT-33 7.63x25 classic Soviet era service pistols. Which will come out on top, Comrade? Of course, being who we are and what we do, you could make a few bucks betting nickels against Hamiltons that some things will not make it to the range, and unexpected things will take their place. Find out the real results when I rat us all out next month

in GunTech. ‘til next month, break some new ground ‘smithing and shooting, and introduce someone new to each, Jack Landis (800) 797-0867 x 106

Producer’s Cut

by Keith Hezmalhalch AGI/GCA Executive

Video Producer

and then there were none . . . You might think you know what I’m referring to in that subtitle but you’d most likely be wrong. As I was starting to think what my first subtitle should be during to this whole COVID-19 “thing,” this funny picture popped into my head. There was a movie waaaaay back in 1966 called “Ten Little Indians.” If you haven’t seen it, it is well worth watching. Basically, it’s one of the first: “guests at an estate dinner are locked in until the murderer is found, but they all keep dying” movies. Hence the “and then there were none” reference. Many of us have been locked in for quite a while now, so this humorous picture just popped into my head, one of many similar scenarios playing out in homes and estates across America as families are “trapped” in close confines with each other. Ok, if you don’t see why it’s funny it’s because “families” barely even exist anymore, let alone spend any real time together. I can just see them. They are hunkered down in the farthest corners of the house, practicing “social distancing” not for the virus, but for survival. Tapping away at their cell phones, texting friends on the “outside” and watching cat videos, but slowly, one by one, they just start disappearing as the Matriarch or Matron of the home begins “cleaning house.” I’m sorry, but I think it’s “roll on the floor” funny. Sigh . . . Well, sadly, I feel it wouldn’t be appropriate to just keep writing humor in my column (or would it?) so I’ll get back to some GunTech related information. I told you back in March we weren’t going to let the Coronavirus deter the continued production of GunTech, but it definitely could put a damper on our ability to film the next round of segments we need. always moving forward . . . At this time, we have scheduled a range week for mid May so we can do the testing on a new round of firearms on their way from Ruger, Colt, and others. I am also scheduling studio filming with Ken for both the Evals and the D&Rs. Even if the current “shelter-in-place” limitations are still present it looks like we’ll be able to do the range testing in Nevada, but things will have to loosen up before mid-June for Ken and me to film in Oregon.

isn’t it ironic . . . The good news is our unusually cool spring in Northern California is finally warming up, killing the virus left and right, as it cannot survive in warmer temperatures. Where was “global warming” when we needed it? If this trend continues and the State and Federal governments begin a factually-based, logical restoration process, we stand a very good chance of moving forward on schedule. Unfortunately, when has the government ever done anything based on facts or logic? Obviously, this is one of those things that is truly in God’s hands more than ours, although our preventative measures have made a significant difference. sooo . . . As you do your part in all of this, we are doing ours: keeping the production and delivery of GunTech, the GCA Connection, and the member’s website all in full swing in spite of the numerous hindrances placed in our way. If you are so inclined, we would appreciate any and all prayers for God to make our way clear and guide us in this crazy time and we will continue our prayers for the health and mental well-being of you and your family for as they say . . . “we’re all in this together.” Until next month . . . in GunTech.

You can call me with the answer ONLY if: 1: You do not have email access.

2: You call (800) 797-0867, ext.104 between 0800 - 1700 PST Monday - Friday.

3: If you get my voicemail, leave your name, phone number, and guess. The voicemail time stamps, so be CLEAR with the info.

Email Jack at jlandis@americangunsmith.com and let him know what you think it is.

All you need to qualify for First thru Honorable Mention prizes is a guess as to what this part (or assembly of parts) is. Good Lord Almighty, if this isn’t a slam dunk, I must have accidentally published this in the Ladies Home Journal! You don’t need the specifics to qualify for these prizes, just the basics. After that, if your response is one of the places listed below, You Are A Winner! By the way, James, it is NOT a one-legged, steel Praying Mantis.

For ”Dang You’re Smart” points we will require the part’s actual name (Spoiler Alert!! That actually describes what it does) and the gun it goes in. This month we’ll stay with awarding the first three prizes and Honorable Mention to, respectively, second correct answer, the Guy in the Middle +2, fourth from last before publication, and sixth correct answer.

Part as shown is smaller than actual size.

This month’s winners are those who correctly named the tool from GunTech 167 in March, 2020. This month’s part will have its winners shown in the July, 2020 issue, GunTech 171. This month we had twenty-two players, twenty-one of whom recognized the Brownells 1911 Lug Iron tool for deburring and polishing the locking lug area of a 1911 slide, thus qualifying for First-Honorable Mention prizes and “Dang You’re Smart” points. Clearly, we have a gaggle of Gene Shuey’s “Building the Ultimate 1911” students out there. The other thought it was a Receiver Rail Polishing Tool . . . .yeah, I could sorta’ see that, not a bad guess at all. But really, Full Auto, a replacement for toy guns in the PRC that will also curl your hair?? We said we’d take the fourth from last before publication, second, Guy in the Middle, and sixth correct answers for the first three prizes and Honorable Mention. This month’s players are comprised of sixteen veterans and five first timers, one of the first timers is this month’s Honorable Mention winner, Jim Morge. Congratulations Jim, and to all the rest of our players. Well done, gentlemen. Dang You’re Smart Winners – Enterprise is rewarded, players. 80 points for each of the Terrific Twenty-One!

We can’t post your points if you have not signed in to the GCA Members website and filled out your particulars!

Winners announced in GunTech #171 (July 2020 issue)Correctly identify the part shown here and be a winner!

I first saw Bob Dunlap’s 1910 .425 Westley Richards rifle

after Bob passed on. I happened upon this beautiful firearm when I opened Bob’s gun safe while doing inventory. I knew Bob had a stock made by world renowned Stockmaker James Tucker, but I had not seen it yet. James Tucker is a member of the American Custom Gunmakers Guild and was actually a gunsmithing

student of Bob’s at Lassen College. James also worked for Bob for a stint before he embarked on

his own successful journey. I was fortunate enough to have met James at one of the ACGG shows and I have seen some of his other work up close, truly astounding. Before the rifle was sent to James for restocking, Ken Brooks did some of the metal tuning on the gun. The rest of the work was done after James took possession of the rifle.

The rifle itself is an interesting

firearm. It was made by two centuries old British manufacturer Westley

Richards in 1910. The rifle uses a standard 98

Mauser action to fire the .425 Westley

Richards cartridge. This configuration

allows the dangerous game

hunter to load 5 magnum

express cartridges into the gun’s magazine via a Mauser stripper clip, plus one in the chamber. This type of rifle was also popular for culling herds for population control, etc. Both of these professions benefited from using a fast loading Magnum caliber rifle. This rifle is light enough to pack around all day, yet heavy enough to absorb a good portion of the recoil forces. The .425 Wesley Richards cartridge will smack a critter hard and can put them down fast. The .425 Westley Richards cartridge, or Westley Richards .425 Magnum Express, was designed by the company’s lifelong employee Leslie B. Taylor (1863-1930) in 1909. Taylor also designed the

Westley Richards metal capped bullets, among many other innovations. The original recipe for the .425 WR cartridge uses a 410 grain bullet, 65 grains of Cordite and a case with a rebated rim, which allows the use of stripper clips for fast reloading. The parent case is a .404 Jeffrey bottleneck case with a rebated rim. When fired, the bullet can achieve a velocity of 2,350 fps and the muzzle energy is up

Leslie B. Taylor became Managing Director at Westley Richards in 1899. Taylor also authored the book, A Brief History of The Westley Richards Firm, 1812-1913.

The rebated rim case on the .425 Westley Richards cartridge allowed the use of stripper clips to load the rifle.

around 5,010 ft/lbs. The Mauser, being a controlled feed rifle,

prompted Westley Richards to develop a proprietary single column extended magazine to reliably feed this type of cartridge. The cartridge is fed up between the extractor and bolt face from the magazine and guided forward into the chamber by the bolt. In order to obtain a more affordable rifle, some design changes allowed the standard staggered column Mauser magazine to be used. If you are interested in reloading the .425 Westley Richards cartridge, you can buy new .404 Jeffrey brass from Hornady or you can use once fired .404 Jeffrey cases. The bullet’s actual diameter is .435” and they can be acquired from Hawk Bullets (www.hawkbullets.com) or Woodleigh Bullets (www.woodleighbullets.com.au).

Westley Richards was founded by gunsmith William Westley Richards in Birmingham in 1812. During the 1800s, William was responsible for designing many rifles for the British Army. He also patented the first flip-up sight, which was also used by the British Army, as well as numer-

ous other firearms patents. John Deeley, of the Anson & Deeley Boxlock action fame, was the Commercial Director for Westley Richards during the 1870s. Leslie Taylor would continue work to improve on the Boxlock system in 1913. The firm is still in operation and is one of England’s oldest gunmakers. If you want to check out some other exquis-itely crafted rifles and shotguns, visit the Westley Richards website. You will be amazed. www.westleyrichards.com. It’s hard for me to call this $10,000 rifle or any other .425 Westley Richards rifle a “Poor Man’s Magnum,” as it is so often called, but if you have ever been to a Safari Club International Show, it all makes sense.

“Full” choke will show a 0.040” difference in diameter. These are the general dimensions, if your choke is off by a couple of thousandths it is not a crisis. There is no absolute standard to which all barrel manufacturers adhere, bore dimensions in shotguns vary widely. You will sometimes get a “tighter” or “looser” pattern from a given choke tube in a particular shotgun. Brand of ammo, loading, and size of the shot will make a difference as well. To get optimum pattern density will require some experimenting. Two otherwise identical shotguns from the same manufacturer may have very different preferences in ammunition, and you can try different diameter chokes. As a general rule, steel shot will pattern about one choke “tighter” than lead shot. Therefore, some choke tubes will say something like “Lead-Modified, Steel-Full.” Normally steel chokes are marked as such. Always check to be sure your shotgun barrel and/or choke tubes are steel shot compatible before shooting steel shot in your shotgun. If in doubt, contact the manufacturer of your barrel, shotgun, or choke tube. Choke Tube Lube Choke tube lube is an anti-seize compound. It fills in the tiny spaces between the outside of the choke tube and the inside of the shotgun barrel, in the thread area, to keep the tube from getting ironed into the threads of the barrel. By filling the threads with lube, powder residue build up is not able to seep around the tube. Powder residue build up is a primary reason that choke tubes sometimes get stuck in a barrel after extended use. So, remove and clean the tubes as well as the tube seat in the shotgun barrel on a regular basis. Using choke tube lube will aid in preventing potential problems in this area. Experienced shooters use their choke tube wrench to occasionally unscrew the tube a quarter of a turn or so, and then re-tightening it to make sure it is properly installed and snug on the tube seat. This prevents tubes from accidentally backing out, causing damage to the tube and the end of the shotgun barrel. Published Exterior Dimensions of Choke Tubes. These match the tools that 4D Reamer Rentals LTD stocks. Win-Choke® 12 gauge - .812 x 32 tpi Win-Choke® 20 gauge - .687 x 32 tpi Rem-Choke® 12 gauge - .832 x 32 tpi Rem-Choke® 20 gauge - .702 x 32 tpi Tru-Choke™ 12 gauge - .795 x 44 tpi Tru-Choke™ 12 gauge Thinwall - .774 x 44 tpi Tru-Choke™ 20 gauge - .675 x 44 tpi

SHOTGUNS Before accepting a barrel for machining to accept screw-in chokes, you must measure the outside diameter (O.D.) to deter-

mine if there will be sufficient wall thickness after machining. “Mike” the O.D. of the barrel and the O.D. of the tap for the particular gauge. Subtract the O.D. of the tap from that of the barrel, divide by 2, and this will give the wall thickness after machine, providing the O.D. of the barrel is concentric with the inside diameter (I.D.). A sample calculation appears below. Barrel O.D. (12 Gauge) .850” Tap O.D. (12 Gauge) Win-Choke™ -.814” .036” / 2 = .018” Wall Thickness I DO NOT recommend installations in barrels where the resultant wall thickness will be less than .015”, providing the I.D. of the barrel is concentric with the O.D. If the I.D. is not concentric with the O.D., you will have to make your own decision as to whether the installation will be safe. In addition, you CANNOT install screw-in chokes in barrels whose inside diameter (I.D.) exceeds the following dimensions: 10 ga. - .780” 12 ga. - .735” 12 ga. Thinwall - .728” 16 ga. - .666” 20 ga. - .624” Exceeding these dimensions WILL cause damaged choke tubes and there is a GREAT POSSIBILITY of causing a barrel blow-out! Check EVERY installation before firing to make sure the tube does not protrude into the bore. Back-bored or jug-choked barrels are usually NOT suitable for screw-in choke installation. “Choke” is the difference in diameter between the cylinder portion of the barrel and the constriction at the end of the barrel. This determines pattern density of the shot charge. This difference is measured in thousandths of an inch.

For instance, a “modified” choke will show a 0.020”

difference in diameter.

CONGRATULATIONS TO ALL!

Yes, We Have No Winner

Chief Dan had a technically correct call, but I think we need to stick with the bigger things, ie., Ruger, Colt, and S&W have three different names for the hand and cylinder stop in their revolvers. I hereby rule in my role as “The Grand Arbiter of Dumb Statements” that all are acceptable and interchangeable. Hammer and Striker are not. So there.

Sorry. Chief, but I still love you.

Good luck to all of you in your search this month. GCA Points Await! Keep in mind we’re not talking opinions here, opinions are like noses, everyone is entitled to one. By “Dumb Statement” we mean a real, unnoticed and uncorrected

erroneous statement in the video, i.e. saying hammer instead of striker, Colt instead of Smith & Wesson, D/R instead of Bench & Range, NOT typos in the Connection magazine. Gene K, Gene S, Darrell, and

Mz. Lenée are exempted from the ignominy they and AGI/GCA would suffer in the extraordinarily minuscule possibility they would actually err.

Be vigilant, keep looking, and listening.

Coming Next MonthThe June issue of GunTech is a mega-dose of antiviral vaccine against the cabin fever most of us have been experiencing for the last 60 days. First up, Ken is back at the bench with another Firearm Evaluation. This time he’s scrutinizing the Savage MSR 10. This is Savage’s entry into the “AR” world of firearms. It is their version of an AR10. The question on everybody’s mind is: “If you build yet another entry into the already crowded field of ARs and it is a heavier, bulkier AR10 style rifle, will they come?” Well, if what Ken discovers about this rifle is any indication, there may be good reason for them to show up.

Jack continues his “GunTech Special” on the “Care and Feeding of the M-1 Garand Battle Rifle, Part 2.” This time, Jack dives even deeper into the maintenance and accessories for this venerable firearm. He showcases specialized tools to assist you when working on your Garand, including several designed to aid and simplify many of the procedures necessary to give your gun not only a thorough but also a proper cleaning. This information is at the heart of what gunsmithing is all about. Yes, gunsmithing encompasses making and certainly repairing firearms, but the most important and often overlooked part of gunsmithing is performing proper cleaning and maintenance on them. This is especially important for older, well-made guns like the M-1 Garand because when properly maintained their potential service life is easily over 100 years. We all love to reminisce about guns from the past, but we also love the latest gadgets. What can we say? We make no apologies, it’s just in our DNA . . . After all we’re guys and in this section, we get to do both. When Gene and Keith are walking the SHOT Show floor looking for interviews, they’re always on the lookout for those “new wrinkles.” Two years ago, one of the most surprising new wrinkles was the innovative design of the Archon pistol. This year, they uncovered the new MARS long-recoil operated rifle. Gene does a truly in-depth interview

15

with the designer to get to the details at the heart of his design. Not only does he bring back John Browning’s long-recoil system as it was adopted in the A-5 Shotgun, he made some truly revolutionary improvements that take John’s original long-recoil system to another level. Jack returns in an installment of “In the Classroom” titled: “Inspecting and Grading Barrels: Does Quality Equal Performance?” This is one segment you are definitely going to want to put on redial because not only do you learn about a new, good quality, highly affordable, video bore-scope, you also learn a ton of information about how to inspect a barrel’s bore and how to make sense of what you see. Using the Teslong scope, Jack takes you on a tour of all kinds of rifle barrels, short,

long, light, heavy, small caliber, large caliber, expensive and cheap. Your understanding of what you’re looking at

and what it means will have you ready to pull out your entire collection and begin taking an up-close look at what you really have.

We finish up the June Father’s Day edition of

GunTech with the “Disassembly Reassembly Course.” This month it

covers a classic pistol that some-times gives folks fits when they’re working

on it. No problem, Ken is here to save the day as he guides you seamlessly through each detailed step of the complete disassembly and reassembly

of the Smith and Wesson 457 pistol. Your Father’s Day gift to yourself is more knowledge and practical information. Now you can begin applying it to your latest projects and repairs. Hopefully, after all we have not been able to do this Spring, your mind and spirit will be invigorated and renewed as you watch the June, Father’s Day issue . . . of GunTech.

Note the additional non-reciprocating charging handle on the MSR 10 left side. It is much easier to use scoped and prone than the rear handle.
