The Barnes book shows loads for XMR 2015, BL-C(2), TAC, H4895, Varget and RL 15 for the 62 gr TSX BT bullet.
I have loaded the Varget Max load with 25.5 gr of Varget at 2.250" C.O.A.L. This load shot decent out of my RRA PP 1-8" upper and my Tikka T-3 1-8 twist bolt rifle. The Barnes book has a 1-9" twist or faster warning with these bullets.
For Varget the min load is 23.5 gr @ 2807 fps and the Max load is 25.5 gr @ 3021 fps. I can give you the data for some of the other 5 powders if you want it.
