Are there any special considerations that need to be addressed when indicating and/or chambering a Proof barrel?
I typically chamber with the barrel thru the headstock, using a 4-jaw on the inboard side and a spider on the outboard side. When chucking the barrel I tighten the jaws against a piece of 4ga copper wire that is wrapped around the barrel. On the outboard side I try to use brass shim stock under the bolts in the spider. All this of course is with CM or SS barrels. Should I be doing something differently with the CF wrapped barrel?
