Curl - I agree with 9.3x57, the person and that ctg. would be perfect for your action and one that would get a lot of use if in my cabinet. Better yet, would be a 9.5x57 due to a wide range of easily available bullets from 235's (speer and barnes) to 250 Sierra BT's, perfect for the velocities of that round. As well, a good 300gr. RN Hornady at about 2,100fps would work well for heavy stuff in the bush.
