CFA Action Type & Caliber Classification 2 — Questions and Answers
Question 1: Which action type uses a slide mechanism that must be manually cycled to eject and chamber rounds?
- Bolt-action
- Lever-action
- Pump-action (Correct answer)
- Semi-automatic
Correct answer: Pump-action
Pump-action (slide-action) firearms require the shooter to manually cycle a fore-end slide to eject spent cases and chamber new rounds.
Question 2: The .30-06 Springfield cartridge designation indicates a bullet diameter of approximately:
- .308 inches
- .30 inches
- .30 caliber with a 1906 adoption date (Correct answer)
- .300 inches with 6mm case
Correct answer: .30 caliber with a 1906 adoption date
The .30-06 Springfield designation means .30 caliber bullet adopted by the U.S. military in 1906.
Question 3: A double-action/single-action (DA/SA) revolver differs from a double-action-only (DAO) revolver in that DA/SA:
- Cannot be fired single-action
- Has a rebounding hammer that automatically recocks
- Allows the hammer to be manually cocked for a lighter trigger pull (Correct answer)
- Only functions with rimfire ammunition
Correct answer: Allows the hammer to be manually cocked for a lighter trigger pull
DA/SA revolvers allow the shooter to manually cock the hammer for a lighter, shorter single-action trigger pull, whereas DAO revolvers do not permit manual cocking.
Question 4: In firearms appraisal, a '12 gauge' shotgun designation refers to:
- The barrel length in inches
- The number of lead balls of bore diameter needed to equal one pound (Correct answer)
- The diameter in millimeters of the bore
- The year the gauge was standardized
Correct answer: The number of lead balls of bore diameter needed to equal one pound
Gauge in shotguns is defined as the number of pure lead spheres equal to the bore diameter that together weigh one pound; 12 gauge means 12 such balls equal one pound.
Question 5: Which action type is most commonly found on high-powered precision rifles intended for long-range target shooting?
- Semi-automatic
- Bolt-action (Correct answer)
- Lever-action
- Pump-action
Correct answer: Bolt-action
Bolt-action rifles are favored for precision long-range shooting due to their strong, rigid lockup and consistent trigger characteristics.
Question 6: The term 'rimfire' in cartridge classification refers to the location of:
- The bullet's ballistic tip
- The primer compound within the cartridge rim (Correct answer)
- The rifling twist direction
- The case mouth crimp
Correct answer: The primer compound within the cartridge rim
Rimfire cartridges contain priming compound inside the hollow rim of the case, which is crushed by the firing pin to ignite the powder.
Question 7: A firearm described as 'single-shot' with a 'break-action' most accurately describes which configuration?
- A revolver with one chamber
- A pistol with a single-stack magazine
- A firearm that hinges open at the breech to load one cartridge at a time (Correct answer)
- A semi-automatic with a manual safety blocking single shots
Correct answer: A firearm that hinges open at the breech to load one cartridge at a time
A break-action single-shot firearm opens at the breech by pivoting the barrel downward, allowing loading of a single cartridge.
