If the boolit fits the neck of the cartridge with no chamber interference with its fired neck expansion, then OK, no problem. ... felix

Might want to make sure the throat entrance is tapered out to at least .313" too or it might shave a little lead. The only issue with that is that it gets deposited in the bore, not a safety thing. If it's a .30-30, most of them don't really have much of a throat entrance, just an extended chamber neck and a sharp angle to the rifling, so no problem there.

Green Mountain has barrels in .311 groove and some choice of twist rate at pretty good prices -- you'd need to be prepared to (pay someone to) profile, fit to the action, chamber, crown, and apply any sight or optic mount you need, but you can get an 18" Gunsmith Special for around $50 shipped (longer or larger diameter barrels are more, of course).
