[QUOTE="Kevin Thomas, post: 386578, member: 15748"] Bill, It's almost impossible to set a primer too deep, so I seriously doubt that that's what caused your misfires. I'm with Fitch and Elkaholic here, I think you've probably got a headspace problem. Could be the brass and how far the shoulder was bumped, or, as they pointed out, it could be in the chamber. Few questions for you; You mentioned this is a new rifle, but is it having any misfire problems with factory ammo? I assume that's what accounted for the first 70 rounds you mentioned? Did you use new brass, or fired brass from another source to make up your first reloads? If it was new brass, did you run it through a sizer first? If you did, how'd you set the die up? Usually, setting a factory die to contact the shell holder won't cause a huge headspace issue, but with certain combinations, it's possible. Do you have a gage to help you adjust the die set-up, and see what's coming out of the chamber after a case is fired? If not, I'd recommend one. Plenty of good ones availabel depending on what style you like, but it'll allow you to know whats truly stacking up when a round is in that chamber. The only other thing that jumps to mind wold be too much grease in the firing pin spring, but that's a stretch, and really only applicable when there's way too much and the temps are well below freezing. Dosen't sound like a possibility here, but hey, it's been mentioned now. Keep us posted and let us know what you find. Kevin Thomas Lapua USA [/QUOTE]
