Any more accurate than the other? I've not started loading for my wife's 6 ARC yet but it's coming. I've got a couple lbs each of SBM and H4895 so hoping one of those shoots well. She's got a 16" RAR and shoots factory 108's around 2450 fps. I've got some 107 TMK's I'm hoping will shoot but plenty of 108's as well.Benchmark
XBR 8208
H4895
Varget
Staball Match
One of those should work well for you.
