I load the 180 grain Speer FP for deer and the 220 grain Speer FP for everything bigger/tougher than deer in my 356 WIN, a Marlin 336 SD rechambered from 35 REM.

MD's suggestion about the 225 grain Partitions sounds something worth trying if you don't think that the 220 grain Speer FP is tough enough for your needs.
