37. True or False: If you put the butt of an inertia-action gun like a Benelli against a brick wall it will not cycle when fired.

ANSWER
True - Inertia guns have to be able to move backward to cycle. Gas semiautos, on the other hand, need some resistance to cycle reliably.

38. Of the following, which is the best way to check shotgun fit?

ANSWER
B: Mount and shoot your gun several times at a bedsheet hanging 16 yards away - Mounting and shooting your gun without aiming shows you where it hits in relation to where you are looking. Shooting from a bench shows you the gun's point of impact. Misses at clay targets can be the result of bad technique as well as bad fit. Most people cheek a gun more tightly when they mount it for practice than when they are actually shooting, so closing your eyes, mounting the gun, and opening them to see if the front and middle beads line up isn't reliable.

42. The burning rate of smokeless gunpowder can be controlled by which of the following?

ANSWER
E: All of the above - The chemical composition of the powder, the size of the powder granules, the shape of the powder granules, perforations in the powder granules--they all do their part.

43. True or False: A short-barreled shotgun is the best home defense weapon because its pattern is very wide at close range.

ANSWER
False - Barrel length has nothing to do with pattern spread. At typical self-defense ranges of seven yards or less, even a cylinder bored gun shoots patterns no more than seven inches across. Shotguns are intimidating and devastating up close, and the pellets won't pass through as many walls as a rifle or pistol bullet will.

44. With a double-trigger shotgun, the trigger pulls should be:

ANSWER
B: Heavier in the rear trigger - The rear trigger should have a pull half a pound heavier than the front trigger to compensate for the great mechanical advantage your finger has on the rear trigger. Set that way, both trigger pulls feel the same.

ANSWER
True - Shotgun patterns follow Gaussian distribution. They are denser in the center than at the edges, not evenly distributed.

49. True or False: The .700 Nitro Express is the biggest-diameter sporting rifle currently in production.

ANSWER
True - It's a double made by Holland & Holland, fires a 1,000-grain bullet at 2,000 fps, and people are lined up to buy the thing.

50. True or False: When the last round is fired from an AK-47, the bolt catch engages a recess in the bolt carrier group to keep the action open.

ANSWER
False - There is no bolt catch on an AK-47. The bolt returns to a closed position when the last round is fired, requiring the manual working of the charging handle to chamber the first round of a new magazine.
