[QUOTE="Rogue Hunter, post: 1161074, member: 46048"] Ernie, I ran it up to 82.0 grains of Retumbo last Saturday, and it's starting to show some signs of pressure. Primers were starting to flatten, and there was a slight shiney mark from the ejector. Bolt lift was still easy though. It was raining too hard to put the chrono up, but I suspect velocity was in the 2825-2840 range if it's consistent with the other powder charge increases/measured velocity that I have seen. Five shots went into just over 1/2" at a hundred with this load. The weekend before, I did run it up to 87.0 with Re33, and velocity was 2780 with no signs of pressure. Accuracy was okay with groups running 1-1/2 to 1-5/8 at 300 off the bipod and rear bag. The newer lot of primers that I have now (WLRM) chrono'd 25 fps slower than the first bunch that I had that were 20 + years old, but the SD's were less with the new primers. You'll need to run a few rounds through it when we come to Wyoming in June.:D -Mike -Mike [/QUOTE]
