[QUOTE="Frogman77, post: 318702, member: 15339"] Actually, it's a custom build with a mcgowen heavy barrel with a tight chamber. I don't know the exact neck diameter though. I just want to uniform my necks so they have consistent neck tension from round to round. I've noticed a handfull of brass in my loads that I can visually see different thickness around the case mouth. you are correct, I'm trying to reduce my runout. Don't have the concentricity guage yet. Trying to get the tools to make straight brass first. I don't use an expander ball. I size using a redding body die and the lee collet die for the neck. Going to trim with a wilson trimmer, deburr with sinclair tool. I was contemplating weighing brass, but it seems as though it's really the volume that I'm concerned about. Just trying to minimize the variables. I know what the potential is .25moa or better, just want to get rid of the wacky fliers that seem to follow the brass. (i.e. flyers out of one brass remain flyers reloaded subsequently) how far down do I turn? Just above the line of where the shoulder meets the neck? or do I cut into that line? [/QUOTE]
