kneelingatlas Posted June 21, 2013 Share Posted June 21, 2013 (edited) My buddy and I started reloading recently and I've been gathering lots of data (this forum is a great resource); we started with some 9 minor, then 40 minor, 40 major and today I tested my first 9 major rounds. The first question I want to ask is about the primers: I used CCI SRP which didn't flatten out as bad as some of the 9 major brass at the range after a match, but the primer seemed to expand into the firing pin well slightly. I remained consistent with all the loads from 153-179 PF, below is a picture with 124gn loads on top and 135gn loads on the bottom, highest PF on the left: I shot two different pistols: my CZ TS (5.1" barrel) and a small frame Tanfoglio (4.1" barrel), the primers seemed consistent between the two. No big deal? Edited June 21, 2013 by kneelingatlas Link to comment Share on other sites More sharing options...
kneelingatlas Posted June 21, 2013 Author Share Posted June 21, 2013 Here's the load data if anyone is interested: I shot a few mags with 124s, then 135s of the same PF, the 135s were maybe a hair softer, but that could have been my imagination; they must have been a tick quieter because they had less powder, so that might have been the only difference.
