If sikadog is right (very likely), then just back the die off half a turn and see what happens. If this resolves the problem, then do check that the resized cases will fit into your rifle and that the bolt will close properly. Even backing off a quarter of a turn may do the trick.It looks to me as if the die is trying to push the shoulder back and buckling one side of the case.
I will check die setting today. I barely used any lube, it was the Lyman spray lube which I think is excellent and ice never had this before. When I set full length size die should I lower until it touches shell holder and then 1/4 turn lower before locking?+1 on die setting and +1 on safe to shoot (provided they chamber easily)
Didn't notice them before I ran them through die. I don't understand why it has only happened to a small percentage of cases.Are you certain that the cases were not dented after firing? That is an odd place for a lubrication dent.~Muir
What is the best method for setting depth of full length sizing die? I'm using RCBS dies.It looks to me as if the die is trying to push the shoulder back and buckling one side of the case.

I will keep you informed of the outcome, I am going to test some more cases this weekend.I would be interested to know the outcome and resolution of this problem, if the OP has achieved it ?
Thank you. I'm sure that I am not alone in being interested in the outcome. I hope all goes well.I will keep you informed of the outcome, I am going to test some more cases this weekend.
