I'm back ! My 6x284 has been given another chance with a new bbl . A 30" brux 8" twist Standard palma contour. It is now a light rifle compared to the former HART varmint contour. Any how on 4/22 1st warm day in NV desert. 53.5 grs of RE#22 behind a Sierra 107 nearly locked up the bolt.So need to pull the bullets on my winter loads. I need to substitute Re#22 with one of Hodgens extreme powders. I wonder if H1000 would be to slow ?
