[QUOTE="Old teacher, post: 822522, member: 48420"] I neck size almost all of the cartridges I reload, but have never worried much about the shoulder bumping issue. The whole idea, as I see it, of neck sizing is to produce a case that fits perfectly into your chamber. I have three 300 Win mags, and the differences in chamber size and shape among the three is significant. Full length sized cases with RCBS dies produces a case which will work in all three guns, but obviously fits none of them well, hence the neck sizing. I keep all cases in boxes labeled for each rifle. The 300 WM sized full length headspaces on the belt; neck sizing produces a case that headspaces on the belt AND the shoulder. Bumping the shoulder back affects that and you lose the added cartridge stability in the chamber, thereby affecting accuracy. As long as the case fits nicely in the chamber when the bolt is closed, why would you want to bump the shoulder back? I set my neck sizing dies to stop right where the neck and the shoulder meet, and I have never had any problems. [/QUOTE]
