Just started working up loads for my AI AWSM at the beginning of the year. I bought both H4831SC and RL25. Started with the H4831SC and have had great results. Consistent velocities and low SD for accuracy groups. No load tested over MOA with better groups sub 1/2 and the best load at .350". Best load is 250gr Scenar over 89.8gr at about 2935fps.
I loaded up 40rds of RL25 this past weekend in groups of 5 from 90.5gr to 94.0gr, 0.5gr increments. I couldn't get a group to shoot under MOA. The SD did finally start to drop into single digits for the 93.5 and 94.0 groups at about 3000fps, but they were still big groups. Could the powder be the problem? Seems like most people were satisfied with RL25.
I have to wonder if there is a mechanical problem going on elsewhere as well.
