I am in the process of rebarreling a Savage 111 .270 win into a 6.5x55 swede. I have most of it figured out by reading on here but I have one question I can't seem to find the answer to.

With a bolt head of .473 (.30-06 based) can I reliably feed/extract brass that has the "correct" base diameter of .480 particularly PPU brass.
