Off topic and if there was a target measured in years the miss would be in the neighborhood of 10 years+. In the big inning reloaders purchased RCBS dies for the 38 Special. Then came one of those ‘AND THEN’ moments. RCBS made a set of dies for the 357 Magnum. (For those that are not listening) The same reloaders that purchased 38 Special dies also purchased the 357 Magnum dies.
WHY? I do not know; but I suspect there were reloaders that were afraid they would loose their place if they adjusted the die to, above or below contact with the shell holder. On the other hand there were reloaders that adjusted the die every time they used them. The reoader that adjusted their dies did not know they could not size and seat 357 rounds with a 38 Special set of dies.
And then! It got better.
I have little interest in how the Germans do it. I secure the die to the press with the lock ring. I do not secure the lock ring to the die. But if I did leave the lock ring loose I would lube the thread. I like clean threads and I remove the slack between presses and die.
