You really cant go wrong with most high powered rifled at 200 yards or less i would say, 270 is what i shoot, so when i say i would get a 270 i guess its based on that, lol , Heck my buddy killed one at 300 + this year with his 243, dropped in its tracks, get a good rifled, get to know your gun, and u will be set. One thing i would like to say though... i wouldnt go with a caliber just cause its bigger, dead is dead is dead, all day long, shot placment is the key
