This is exactly the reason I haven't done ANYTHING with a 14" Custom Shop .30 Herrett barrel I picked up months ago. I like the concept of the cartridge, and have tons of .30-30 cases, but case forming and reloading dies for the case are crazy expensive...you'll easily pay more for the dies than the barrel.I also had a 14" in .30 Herrett. While accurate with jacketed and cast I'd not do it again just because of all the work making cases
I've debated on having mine reamed to .30-30 AI, but can't make up my mind....may end up trading it for something else, as I already have several 14" .30-30 barrels.
