[QUOTE="MNbogboy, post: 1846339, member: 18849"] I also could not tell from the pictures if the primer itself is "set back". It does look like that somewhat. Full length sizing die instructions often say to bump the shell holder to the die and then "cam over". These "one size fits all" instructions are just that. They "work" for most instances but are not optimal for extending brass life nor for consistent ammunition. Not saying your die might be set up wrong but it may be something worth looking into. There are many threads & posts within this forum concerning full length die set up. Simple "scotch tape" tests will help you determine where you are at. As mentioned above a little extra case head space can give "false" pressure signs. However, your primers do look mostly normal and your velocity falls where it should your thoughts on charge weight trials between 56 & 57 make sense. Hornady brass if headspace properly and run at normal pressure will last 10 firings in a lot of cartridges. Hotrodding it will loosen primer pockets prematurely. Good luck, Randy [/QUOTE]
