[QUOTE="Deleted member 107666, post: 1700548"] I did manage to get the neck turned to match that depth up the shoulder (from that pic above)...I'd stopped short last time, right at the junction, not understanding the purpose and scared I'd thin the shoulder too much. They looks good now. Awesome info, thanks. I don't have a way to measure what the necks expanded too when fired. The necks are turned to .013 (too late to go back now. That is .334 with a bullet seated. After firing I used a .331 bushing to compress back down, and a .306 expander mandrel from 21st century in their die to set final tension of .002 (give or take with spring back) I'm vest $250+ in the redding dies, bushings and the expander mandrels. Too late to change now, but if there is a better way, or better sized I can use to reduce run-out and overworking brass, I'm all ears. The chamber was ground on a custom reamer, I'd have to ask Mike at Mile High the specifics on it, they ground the chamber. Pics below as they sit ready to prime/seat bullets. [/QUOTE]
