  1. What is the purpose of the crimp at the mouth of a shotgun shell?

    Answer: To hold the shot charge and wad in place until firing

    The crimp folds or rolls the case mouth closed to contain the shot charge, wad, and powder until the shell is fired.

  2. Which of the following calibres is classified as a centerfire cartridge?

    Answer: .308 Winchester

  3. What does 'FMJ' stand for in ammunition terminology?

    Answer: Full Metal Jacket

    FMJ stands for Full Metal Jacket, describing a bullet where the lead core is completely enclosed by a harder metal shell, usually copper or gilding metal.

  4. A firearm owner discovers a box of ammunition that has been stored for 20 years in a cool, dry location. What should they do before using it?

    Answer: Inspect cases and primers for corrosion; test-fire a few rounds carefully before relying on it

    Well-stored ammunition can remain serviceable for decades; visual inspection for corrosion, verdigris, or damaged primers and careful test-firing is the prudent approach.

  5. What is a 'hangfire'?

    Answer: A delayed ignition where the cartridge fires after an unexpected pause following trigger pull

    A hangfire is a delayed ignition — the primer is struck and a delay of up to 60 seconds may occur before the cartridge fires.

  6. Which shotgun shell designation indicates the largest individual pellet size among standard birdshot loads?

    Answer: #2 shot

  7. What is the correct action if live ammunition is discovered in a firearm that was believed to be unloaded?

    Answer: Keep the muzzle pointed in a safe direction, engage the safety if available, and carefully remove the ammunition

    Keeping the muzzle in a safe direction at all times while carefully unloading the firearm with the safety engaged is the correct and safest procedure.
