Squirrels and rabbits are why .410 and other small size shot guns are available. If you're hunting rabbits with a .22 it isn't because you're hungry.
Man is the only animal who hunts on a full stomach.
It is one of the frist choices for putting meat on the table.
Shotguns ruin to much meat head shots only for the 22. I found no need for a shotgun
Plus shot gun shells cost a lot more then 22 ammo for the same amount of meat. There is game that a shotgun is more suited for but rabbits and squirrels naw.
