I just started reloading some rounds for ladder testing. I am using H-1000 and RE22. The H-1000 is compressed starting at about 76 grains. The RE22 doesn't compress at all. I can't get the H-1000 loaded rounds to the same overall length consistently from bullet to bullet. Could the powder be causing the inconsistency? I'm using a Stoney Point comparator for measurments and am having no problem keeping + or- .001 with the RE22 loaded rounds. I'm using 200 gr. Accubonds in a 300 win mag. and seating them so they fit in the magazine. Overall length is 2.780 (after zeroing off the face of the comparator). The H-1000 rounds are + or - .004. Any Ideas would be appreciated.
