338 is hard to beat, the caliber....in '06 to WM brass will do plenty. A 225 Partition will do about all that needs doing, and a 200 BT/AB is on tap for smaller animals at good ranges, a tad flatter.
That said, a 9.3 would not disappoint on shots to say 200-250 yds. You sacrifice some range going to these heavier larger bullets, in the common rounds like x62. IIRC, the 250 is in the AB, and a 286 will handle most anything fairly hit, but more dope is required.
