Just had a rifle re barreled with a fluted 1-10 twist 280 ackley. Its a short heavy little bugger that I plan on running suppressed with a 168 ( if I can) berger hunting vld. Berger shows it being stable above 5000 feet but im trying to figure out what powder to run. In my stock ive got imr 4350, imr 4831, h4831sc, imr 4955 enduron and imr 7977enduron. Thoughts? Suggestions?
