Thanks, that's the info I'm looking for (what I need to look for...)
I thought I'd read about headspace issues and neck-sizing brass only for these rifles somewhere (?)
I could buy a no-go, or perhaps some brass and add a couple of pieces of tape to the case to simulate a no-go.
Since it's a rimmed cartridge, are these potential issues related to worn lugs/raceways?
