I've got a 22 BR on the way, 1 in 12" twist 26" Shilen on a 700 Action. I've got Lapua brass and some 55 grain BlitzKings as well. I've been very happy with Varget in my .223, but the Sierra load data I've seen seems to lean toward Benchmark in the BR. Anyone have a recommendation for one or the other, or another powder I should consider?
