Wanting to hear opinions or methods of resizing. I just got away from neck sizing (after 3 rounds I have FL and start over PIA) and went to full length resizing. I'm bumping the shoulder .002 on fire formed brass. Annealing every two shots. I'm using whidden FL bushing dies with .002 neck tension. I'm getting .001 spring back when measuring a loaded case, which I think is enough as I can't twist the bullet by hand.

There's really 3 methods for sizing cases- FL, neck only size, and a partial FL size where you bump the shoulder back a set amount.

.002"-.003" shoulder bump with a FL sizing die will generally work well for bolt rifles. It works the brass only a slight amount and will prolong brass life. I do this on my personal 308 Win, 300 Win Mag, and 6.5x47 Lapua ammo. But you still need to chamber check the brass. Some belted mags, or even 308, will swell just above the case web area, about 1/16" to 1/8" above the rim. The partial FL sizing does not reach down to this area, and can cause tight chambering in the case web area. I have seen this in multiple belted magnums.

Neck sizing, I'm not a fan of, since it causes chambering problems. There's also no accuracy advantage neck sizing, that can not also be accomplished with a partial FL size.

FL sizing is required for proper chambering in any semi auto rifle, or breech chambered rifle (like a break open action), since there is limited to no mechanical leverage in chambering. When in doubt, FL size.

Sorry, Partial with FL is the method I use on all bolt guns. Always load to spec on AR's. Good info Chad....as always.

I had always used partial FL sizing, but decided to give Lee Collet dies a try some time back. I couldn't say whether it has helped improve accuracy, nor could I say it has hurt in any case. I do suspect it may have helped a tiny bit with one rifle but I haven't messed with that one enough yet to be sure. I'm going to keep using collet dies, though, because there is one thing I absolutely LOVE about them: no case lubing! I'm prepared to size case bodies back down when necessary, but I have found that I get at least two firings neck sized only. Some rifles seem to allow more.

On the full sizing Type S die with the bushing is which,,,,the full sizer or partial full sizer? Can you do a shoulder bump with the bushing? I have never tried to shoulder bump it because I have a separate full sizer without the bushing that I shoulder bump back .001
