[QUOTE="MagnumManiac, post: 2101373, member: 10755"] When I used bushing dies that were only for necks, I would only size 80% of the neck. At the time, I thought this was best and gave the smallest groups. Alas, I was mistaken because going to dies with honed necks and modified expanders and using a mandrel with custom sizes that size almost all of the neck gave me tighter groups. The difference is from working the brass the least possible amount, I believe. I am a big believer in Forster dies and honed necks with modified expanders. I only skim turn my necks nowadays, just enough to clean them up. If you work your brass very little, then it’s concentricity stays very stable and is repeatable between sizings and firings. Cheers.
