RE: what grain are you using on whitetails
For the Omega I used 300 gr Hornady SST, 100 T7 2f, win 209 Primer but have switched to 300 .451 Nosler Partition HG PP w/ 110 gr T7 2f and a 209 Win Primer. (This load is intended for moose as well as deer/bear and is very accurate in my Omega).
My Lyman GPR .50 is strictly .495 PRB over 90 3F Goex w/ 3f Goex for prime.
The Traditions E-Bolt likes 100 gr Pyrodex RS, Win 209 Primer and a .452 240 gr XTP Mag
