2
A Firearms Safety Mechanism

• Dont be afraid to ask if you dont know how a
  firearm works
• never trust the safety mechanism
• safety prevents the gun from firing
• safety could fail

3
Damascus Barrel

• Older or custom made barrels which were typically
  made before the turn of the century
• weaker than modern barrels

4
Airguns ( three kinds)

• Pneumatic- use a pump system
• CO2 powered-use compressed CO2 contained in a
  steel cylinder
• spring- involves a spring that is compressed by a
  lever

5
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

6
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

7
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 or
  shotshells into the chamber( loads, unloads and
  ejects ammunition)

8
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

9
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

10
Rifles

• Sights are important parts of rifles
• three general classes
• open sight-least accurate
• peep or aperture sights
• telescope sights- most accurate

11
Rifle positions

• Four standard positions
• standing-most difficult
• kneeling-forms tripod
• sitting-forms tripod
• prone-most stable

12
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

13
Firing Techniques

• Hold breath, gently squeeze trigger with steady
  pressure until the gun fires.
• Never jerk the trigger or slap the trigger

14
Shotguns

• Several gauges
• 10,12,16,20,28 and .410 are most common
• smaller the number the larger the bore

15
Shotgun Position

• Almost always fired from a standing position.

16
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

17
Shotgun Range

• Not a long range gun
• depends on the shotshell
• average is within 45 yards

18
Ammunition

• Divided into two categories
• cartridges- handguns and rifles
• shotshells- shotguns
• Primary components of cartridges
• case
• primer
• centerfire or rimfire
• smokeless powder
• bullet

19
Ammunition

• Primary components of shotshells
• case
• primer
• smokeless powder
• wad and shot

20
Handguns

• The safest way to carry a handgun is with no
  round in the chamber
