.22 Shorts are not as loud as the Longs (which are also still available) and LR. They do not have as much energy as the other loads and make for ideal pest control rounds where you don't want to disturb livestock, neighbours, etc...I also use them on the trap line. If you get a fox, etc...in a leg hold trap, you fire a single .22 short straight down, between his eyes. The .22 Short lacks the energy to exit the skull and will typically bounce around inside a couple of times resulting in a very fast and humane kill.
A humane kill of an animal in a trap.........mmm right......
