My bad, I thought we were talking about military rifles not small guns that children use to shoot squirrels at 20 meters
But if you want you can also call me dumb because there are are much smaller toys like BB guns that you can use to shoot the neighbor's dog for a good laugh
Nearly all of the militarys weapons spawned from the basis of a civilian one.
.22's are no joke either, they are just as capable as killing a fully grown armored man than just eviscerating a squirrel.
a .22 LR is used by multiple militaries around the world for assassinations and even in assault weapons. You are in fact, speaking ignorantly.
