Thanks for the suggestions aandabooks, but it has to be a carbide reamer. High speed steel (HSS) reamers won't cut nitride coated barrels. Brownells and Midway only sell HSS (high speed steel) reamers. Same (HSS) for the rental companies. I've bought many reamers from PTG, and know exactly what you're talking about time wise and lack of communication. That's why I thought I'd ask here if any one knew of a source for a carbide reamer other than PTG. To their credit, all the PTG reamers I've bought have been excellent.
