My uncle used to use a 8lb sledge hammer on med - large farm animals that were designated as table food years ago. Seemed to work 100% of the time. YMMV
yes -- agreed ... or a .22 short properly placed.... but my question to the 'OP' is: are you hunting the sheep or slaughtering the sheep? If you have to stalk them and 'wack' them at a distance... you may need to have enough velocity and bullet weight to be effective ... otherwise keep it simple and quiet (and safe) with a hammer or simple and quiet with a .22 short....at 'short' range (point blank!)
