Is this load with the SAUM or the 284?use 59grns(freebore .220) or so N165 with 180 vld or hybrid. It will give you 2950fps with stellar accuracy. Barrel life will be extended greatly with N-165. If that does not work try H1000 around 60grs. This is in my barrel so work up. The two powders i mentioned here will extend barrel life by at least 500-600 rounds. I did my first couple with H4831sc and barrels went south at 1400 rounds.
Thanks,
Lloyd
