[QUOTE="RegionRat, post: 2980417, member: 57231"] I agree with experimenting with the brass prep and neck tension details above, and in addition just food for thought... Does this rifle shoot any other loads and produce a small speed variation? If it does, then disregard the following since this would exonerate the ignition system. If it doesn't, have we checked priming details or tried other primers? Have we checked the ignition system for any defects or a weak firing pin spring? Is there excessive headspace? Primers and how we set them off can be half the battel when it comes to poor speed stats. This concept includes defects of the actual primers, their installation, and the firing pin performance. If the bolt maintenance is neglected, or if there is a mechanical defect that causes erratic friction, the ignition can be responsible as often as the brass prep or recipe. If playing with the brass prep or recipe doesn't improve, I would have a hard look at the firing pin spring and parts. Sounds like a screamer of a rifle. Good luck and have fun. Merry Christmas.
