I finally scrounged a couple of boxes of Holland's Super 30 for a nifty pre-64 Winchester M-70 I recently acquired. My problem is that three of the rounds had been fired... In a 300 Wetherby chamber.
Normally, I'd just discard the three cases, but these are NOT normal times!
So. My plan is to size the brass first in a 375 H&H die (Without the expander, of course), and then size in a 300 H&H sizing die, hopefully to restore the cases to their original dimensions.
Will my plan work? If not, can you advise me regarding a better way?
I'd give it a shot. Nothing to lose. I've used re-sized 375 brass in my 300 w/o problems.
