[QUOTE="codyadams, post: 1552451, member: 87243"] I find primers to be about the least consistent way to judge pressure, primer cup hardness varies from each manufacturer, and it shows. Also cratering can show on lower pressure loads if the fireing pin hole is sloppy on a rifle. Measuring the web, primer pocket stretch, case head markings, bolt lift, velocity and primer as a whole seems to get the best results. On one of my remingtons if you just looked at the primer, you would think it is about to blow. But the brass has lasted over 10 fireings, never had any ejector marks, velocity usually had single digit e.s., no heavy bolt lift, etc., but the fireing pin hole was sloppy and I had cratered primers. Not trying to stand on a soap box by any means!! Hopefully it's just a similar case, would be nice to see ya get more velocity and lower e.s. as ya work up!! [/QUOTE]
