yeah...my plate has seen some wear from the torch after tens of thousands of 300 blackout...but it still works fine. Will definitely last longer this way though.
I have also been annealing 500 S&W to see if it helps them last longer. On the magnum handgun rounds I usually get split necks at about 4 loadings...but I am having to put a pretty heavy crimp on them to keep them from pulling with recoil. I assume annealing with help stop the split necks...but time will tell. I'm on the second loading on this 500 brass.
