Lee lock rings: Basically, I don;t like the things. So far there has been no problem for me yet (note yet). The only handgun cartridge I do is 357 SIG on Lee dies. The Lee lock rings have been swapped out for 1" Dillon rings. The Lee rings have been left on a T Mag. The FL sizer and collet sizer ( 257 Roberts, 7mm-08, 308, and 7mm Magnum used as needed.) are on this Lyman. Incidentally, that collet die is great for not screwing up brass. Over the years it been necessary to deal with dies attacked by Bubba. You learn how to remove lock rings that had been attacked with vice grips. Overall, my experience with major brand dies has been good. The only truly fouled up die to pass through here was a Lyman 45-70 where the sizer was not finished out. Lyman replaced that very quickly. One way to solve the alignment problem is to check out the Co-Ax press. This press allows movement with the shell holder and the dies. I have a long history of RCBS taking care of me, the customer. Most of the reloading manufacturers will take care of you. Don't ask Bubba how to set your dies!
