Here’s the reamer Grizzly sells. Hit up the reamer rental places too, usually they have a link to the print. If you're planning to buy a reamer yourself, call the shop you plan to have make it, and ask them. Ive been using manson lately. They usually email prints within a few seconds of getting off the phone.
Thanks for the prints , they were great help in drawing up a new set of reamers for the new multicaliber gun
Made the reamers localy ,all carbide and spiral fluted should last for some time
