So when I got my AR10 in 6.5 Creed, I bought 200 rounds of S&B 140gr for $12 per 20. Best price I could find for some fodder ammo to play with the new rifle. First shots ripped the rim off the brass or and stuck the case. Tried multiple time single feeding. Set that ammo aside until I just got a 6.5 Crred bolt gun and decided to try it again. HEAVY bolt and blown primer. So I just tore down 80 pieces from a single lot # and measured CBTO, COAL & charge weight. Will do the stats later, but wanted some help IRVING the powder. The avg charge weight was 39.2gr and a picture is attached. Any help would be appreciated.
