[QUOTE="Deleted member 25294, post: 1579027"] It was 6.5 SAUM Bertram Brass, case capacity averaged 1.5 grains more than my Norma brass. By hitting pressure early I mean I couldn't reach the same velocity with Bertram as I cound with Norma cases. I had shiny extractor marks before coming within 50 fps of my Norma loads with the same powders. Also as far as case capacity, the most variation I've measured with Norma brass is .5 grains. I was getting 30 FPS variation with Bertram brass between two sample groups of 6 cases each. I've had better consistency with Winchester brass for 1/3 the price.. [/QUOTE]
