[QUOTE="gray wolf, post: 272005, member: 15129"] Hmmm? I could be wrong here but I thought that brass after repeated firring or sizing gets work hardened and that is what creates spring back. Isn't that why we anneal our brass? Anyway the gentlemen Say's it is with new and old brass so lets forget the spring back for now. RCBS dies have gotten a bad rap from some folks. I think in many cases justified. I would say it is possible that your die is a little undersized making the cases a little to small AND your expander button may be a little undersized also. ---.201 on the ball sounds like it may be little small. Don't get mad but you say you are into bushing dies and are capable of neck turning--so may I ask why you would want to use a nasty expander ball ? Any way--RCBS has great Cust. service and would replace the dies if they are wrong. Just trying to help. .006 on the neck tension is not that tight --a little yes but should be doable But if you prefer .003 then that is what you should have by all means. That is why we reload--I like .004 two thou per side. I am sure you have chamfered the inside case mouth (just checking) One last thought are you using the rcbs seating die? Who knows it could have a problem. If you are shaving bullets it can't be helping your run-out. GW. I just grabed a die and checked the expander ball. It is a Redding 270 die and the ball is .276. Bullet is >277 [/QUOTE]
