Do you have the laminate or the Kevlar stock. I have both tho I haven't had the chance to wring out the Kevlar one yet.
50gr Nosler BT 35 gr Varget Winch case and WLR primer got me 3750 fps and will shoot 5 shot 1/2 " all day long
40 gr BT 37.0 gr IMR 4064 got 4060 fps and the Pdogs do not like it a bit.
You need to try Accurate 2520
40 gr BT on top of 37 gr got me 4080 and 1/2 " groups with no heat problems and shoots very clean. Runs thru a measure like water.
