Greetings all; will try to keep this concise. I think I've boiled down the answer, but I could be missing something.
Casting/powder coating now for .308. I have an average sized diameter of .311-.312. The stock xpand/decap was too narrow, and searches and a post or two here had me trying the x/decap for 303 British, which mics out at .3105-.311. Still shaving powder and exposing raw lead when seated. I guess in my head I should be shooting, er, trying for .313 ish on the xpand/decap. Either that, or size down a little smaller, which doesn't sound like the way to go for possible bore fit reasons. No, dang it, I have not slugged it. I'm skittish of somehow scratching/marring the bore somehow. Or getting something stuck. It's a new (maybe 40 rounds thru it) Savage FCP-SR.
Right now my thought is to place an order thru Lee custom services for a new rod around .313. Am I thinking straight -ish?
On the other hand, the Lyman M die in 30 cal long looks like it might do the trick as well. Any M die voters out there? What sort of opening will that allow me to adjust to? This sounds very much like it would bell the case mouth similar to loading straight wall pistol catridges
Thanks everyone; much appreciate your weighing in on this.
Regards,
