Here is my pet load...
140 Gr. Barnes TSX
57.5 Gr. IMR 4831
Rem Cases
WW Magnum Primers
C.O.L. is 3.250"
Accuracy is + or - 1/2 "

If the TSX is too costly use the 139 GR. SST with 57 Gr. IMR 4831 seated to the cannular. These are deer loads and I use a bigger cartridge for moose.

Rifle is stock Remmy and shoots many loads real well but these loads hammer deer. All the usual pressure warnings to ya !! Good Luck
