Going to look at a .300 win mag that was chambered by accurate ordnance. Build sheet says reamer .300 WM DM SPEC. Does anyone know the specs on what this reamer would be? Looking for distance to lands to see how it compares with the chamber on the one I currently have. He says he asked for it to be throated for 215 hybrids but doesn't know anymore than that as it's never been loaded for.
