If you don’t live in a rural setting, why would you want snake shot? You don’t want to use that as anti-personnel rounds. And in large caliber rounds the shot is usually in a plastic covering.
I’ve heard of guys loading snake shot into pistols for the first 2 or 3 rounds, for short range. Why wouldn’t I want to use snakeshot as anti-personnel rounds? One of the considerations other freepers brought up was that the bullets would go through walls and hurt neighbors. Snakeshot probably can’t do that nearly as much.
