I just got a 700 VSF in 22-250 last December to use as an excuse to start leaning how to reload. The only powder I've tried so far is Varget and I'm almost out of it and I'm looking to try a new Extreme powder. Benchmark is really looking like it might be good. Has anyone used it? I'm looking to use the 45 gr TSX, A-Max 52 gr and 50 gr Ballistic Silvers for bullets. Thanks for any info!
