is RL22 over H4831?????
Lapua case, 210M, 142SMK, [email protected] = 2803fps
Lapua case, 210M, 142SMK, [email protected] = 2769fps
These were both from CBS to 5 shot averages. After being fouled by 10, both powders spead up 30fps. SD for the H4831SC remains 10fps or better in a fouled bore with Rem 9 1/2M's.
My last two lbs of H4831SC have run considerably slower (170 to 200fps) than my first 5lbs, but it's still the most accurate powder from my 26" 6.5x284.
