[QUOTE="CRNA, post: 734154, member: 22495"] Ok, been loading for a couple of years. Loaded many rounds for my 7mmRM that I use in competition as well as hunting. Never had this problem before: I loaded 60 rounds two nights ago for a competition that's coming up next month. All was well. I start loading tonight and I am having a big variation in my OAL (measured from the ogive with my bullet comparator in calipers.) I loaded 30 rounds that had a spread of 0.0010" between that lot. I quit loading until I figure out the problem. They are Bergers, from a 500ct box that I have used probably 2/3 of. Never had an issue. I thought it may be dirt on the shellholder. Nope. I thought it may be dirt in the comparator. Nope. Thought it may be batteries in the calipers. Nope. I rechecked the lengths of the rounds loaded two night ago and they are dead-nuts on the money (maybe .0001" variation). What gives? The die has not been touched in two days. Nothing has changed. Any help that anyone may think of that I haven't yet would be greatly appreciated. Steve [/QUOTE]
