1 Modern Firearms

2 Safety Mechanism Never trust the safety Prevents the firearm from firing Could fail! Don’t be afraid to ask if you don’t know how a firearm safety works

3 Damascus Barrel: Older or custom made barrels which were typically made before the turn of the century Weaker than modern barrels Couldn’t fire as far and straight

4 Airguns: 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: Use 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 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 Gauges is usually marked on the rear of the barrel

7 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 in the part that moves the cartridges or shotshells into the chamber (loads, unloads, and ejects ammunition)

8 .22 Rifle

9 .22 Hornett

10 243

11 270

12 30-06

13 7 mm

14 Stock, action, and barrel are 3 main components of guns There are 5 categories of actions: - break -pump -lever -semi automatic -bolt

15 Rifle sights: Open – least accurate Peep or Aperture Telescope – most accurate

16 Dominant 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

17 Rifle positions: Standing – most difficult Kneeling – forms a tripod Sitting – forms a tripod Prone – most stable (lying down)

18 Firing Techniques Hold breath Gently squeeze the trigger Apply steady pressure Never jerk or slap the trigger

19 Range or Distances.22 caliber bullet (rimfire) can be dangerous at a mile or more Centerfire bullets ( , etc) can be dangerous at more than 3 ½ miles

20 Ammunition: Divided into two categories - cartridges – handguns and rifles -shotshells – shotguns

21 Ammunition Case Primer -centerfire or rimfire  Smokeless powder  Bullet

22 Shotguns: Measured in gauges 10, 12, 16, 20, 28, and.410 are the most common The smaller the number, the larger the bore (inside of the barrel)

23 Shotgun positions: Always fire from a standing position Slight bend to knees and elbows Lean forward a little

24 Shotgun range: Not a long range gun Depends on the shotshell Average is within 45 yards

25 Shotgun choke: Determines the spread or pettern of the shot after it leaves the barrel Three chokes: -full – most constricted -modified – less constricted -improved cylinder – less than modified -cylinder choke – no constriction, shot spreads quickly

26 Ammunition Case Primer Smokeless Powder  Wad and Shot
