A Mr.Bob or a Sir Bob AI, but in reality with the modern +P loads or hand loading the Mr. Bob you will get close to the AI, mine and my son's favorite loads for deer in our AI's is 100gr partitions, and for bigger game, Elk it is the 115 or 120gr partitions. A fun gun to shoot all day because of the lack of recoil compared to a .308, which is a fine cartridge, but you said just for deer!!!

Too many calibers and not enough time for the working man to hunt with them all.
