I hate typing lengthy responses, but the thread pattern for die innards are coarse enough to let air escape as the case enters the die. If he is not over lubing, I would point at the die itself.a friend of mine says he can't full length resize without wrinkling the shoulders he swears he doesn't have to much case lube on his brass uses the spray Hornady sells he thinks it is trapped air it is a custom die they built for him I've never seen it just checking for him.

Tell him not to rule the die out, and Redding should rectify if suspect. Good luck.He said that he can't run the die touching the ram or it does it he backs it off enough to keep it from happening then has issue closing the bolt because shoulder isn't bumped back enough felt it was trapped air I'll have him pull the recapped and try
I'll tell him. DavidDefinitely sounds like too much lube. Clean the die real good and try putting a very thin layer of lube on with his fingers. Spray lube goes all over the neck and shoulder. As the neck starts to size all the lube gets pushed down to the shoulder and gets trapped there. It has no where to go but in against the brass. If he wants to use the spray just wipe off the neck and shoulder with a towel before he runs it in.
