Rifle ammunition comes in different sizes. The smaller the shell, the more powerful it is.

• A. False
• B. True
• C. It depends on the cartridge.
• D. Only for certain calibers.

Answer: (A)

Power comes from the energy the bullet has when it leaves the barrel, which depends on how much powder is burned, how heavy the bullet is, and how fast it is pushed out—not simply the overall size of the shell. The energy is roughly linked to the bullet’s mass and velocity (E ≈ 1/2 m v^2). A smaller cartridge usually can’t hold as much powder, and while it can drive a lighter bullet to high speeds, the lighter mass often means less total energy than a larger cartridge with a heavier bullet and more powder. So you can’t assume that a smaller shell is more powerful. The correct idea is that cartridge power is determined by the combination of powder charge, bullet weight, and velocity, not shell size alone.
