Derimming die steel
Hi
I'm making some 224 bullets out of 22 lr cases.
But the derimming die insert is short-lived, has a lot of wear.
I'm thinking of making one, but I don't know which steel is more suitable, because I made a unit with silver steel(52100) and the useful life was short, because it had quick wear, even after doing the temper.
could someone give a tip?
Thanks
