I've been having an annoying problem where I can't seem to get my die to consistently seat bullets to the same depth. These are being measured at the ogive with a comparator. If it matters, most of the brass is reused federal and the bullets are SMK HPBT 175's. Hornady dies, RCBS press. The closest accuracy I can seem to get with depth is +/-.01. I'll get some that are really close, within .001 and then all of a sudden one will be .005 too short. Then the next one might be long. It's maddening. Competition dies are supposedly adjustable to .001 so is this kind of variance normal with regular dies? And would a competition die really fix the problem? At the end of the day, am I really going to see the difference on paper?
