Can’t say enough abot CCI Stinger ammo. I use them on rabbits and squirrels and, if head shot, the settle the argument - NOW. Actually, they hit so hard and have such nice expansion for a .22 that they usually explode Thumper’s head. Not a pretty thought, but they don’t run off to die someplace in pain or where you can’t use them.
You don’t need HP for rabbit or any other small game.
I put down cows with a .22 solid, it’ll put down small game and they don’t run it you hit anywhere in the vitals.
