A 3.5 in gun kicks pretty hard but if you get a gas auto with a $40 recoil reducer it's alright. but if you take the time to set it up right you can kill a critter just as dead with a 2.75 or 3. the only guns I wouldn't buy for it is a single shot or a mossberg
mostly cause I believe you get what you pay for
and with either on of them your not payin' much
