A Firearm’s “Safety” Mechanism

Don’t be afraid to ask if you don’t know how

a firearm works

never trust the safety mechanism

safety prevents the gun from firing

safety could fail



Damascus Barrel

Older or custom made barrels which were

typically made before the turn of the

century

weaker than modern barrels



Rifles and Shotguns

Uses expanding gas from burning powder

to force a bullet or shot out of the muzzle

main difference in shotgun and rifle is

found inside the barrel

shotgun bore(inside of barrel) is thin and

smooth

rifle bore are thicker and have grooves that

spiral around the bore



Rifles and Shotguns

Grooves are called rifling

spins the bullet making it more accurate

caliber of a rifle is determined by

measuring the width of the bore

shotgun sizes are given in gauges

gauge is usually marked on the rear of the

barrel



Rifles and Shotguns

Always use the correct gauge shell in the

same gauged shotgun(12-gauge shell in a

12-gauge shotgun

rifle and shotguns are usually identified by

their bore sizes and action designs.

Action is the part that moves cartridges orshotshells into the chamber( loads,

unloads and ejects ammunition)



Rifles and Shotguns

Stock, action and barrel are 3 main

components of guns

there are five categories of actions

break action

pump action

lever action

semi-automatic

bolt action



Dominant or Master eye

The one you should look through when

sighting

keep both eyes open when shooting a

shotgun

usually close one eye when shooting a rifle



Rifles

Sights are important parts of rifles

three general classes

open sight-least accurate

peep or aperture sights

telescope sights- most accurate



Rifle positions

Four standard positions

standing-most difficult

kneeling-forms tripod

sitting-forms tripod

prone-most stable



Rang/Distances

.22 caliber bullet (rimfire) can be

dangerous at a mile or more

centerfire bullets(.30-30, .30-06, etc.) can

be dangerous at more than 3 1/2 miles



Firing Techniques

Hold breath, gently squeeze trigger with

steady pressure until the gun fires.

Never jerk the trigger or slap the trigger



Shotguns

Several gauges

10,12,16,20,28 and .410 are most common

smaller the number the larger the bore



Shotgun Position

Almost always fired from a standing

position.



Shotgun Choke

Determines the spread or pattern of the

shot after it leaves the barrel

Three kinds:

full- most constricted

modified- less constricted

improved cylinder- less than modified

cylinder choke- no constriction, shot

spreads quickly



Shotgun Range

Not a long range gun

depends on the shotshell

average is within 45 yards



Ammunition

Divided into two categories

• cartridges- handguns and rifles

• shotshells- shotguns

Primary components of cartridges

• case

• primer

– centerfire or rimfire

• smokeless powder

• bullet



Ammunition

Primary components of shotshells

• case

• primer

• smokeless powder

• wad and shot



Handguns

The safest way to carry a handgun is with

no round in the chamber
