I put a 338 federal barrel on a savage striker action the other night and I used sized brass to set the headspace. No problems, I got a slight resistance to FL sized brass, crush fit with a single layer of scotch tape on the case head, and no go with two layers of tape.
My question is this. I used virgin Lapua 308 win cases to make the 338 fed brass. Any gotchas out there with using brass sized up from 308 to headspace the new caliber? Anything specific I should check before lighting the first round off, on account of being extra careful?
TIA
