I agree with the thunderbolts, dont go there. You can use either.22 or 12ga. Ive shot more yotes with a .22 than anything else because I see them all the time while small game hunting. SHoot them in the head if yopu have a shot. I have a semi auto tho and even the few Ive shot in the chest ive managed to get three or four shots in before they knew what hit them. Thats the beauty of having no recoil. Just be a proficient shooter and youll be ok
