Re: How much slower

Lapua case, 210M, 142SMK, RL22@50.5gr = 2803fps

Lapua case, 210M, 142SMK, H4831SC@50.5 = 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.
