Would a 7mm PRC reamer clean up the chamber of a 7mm Rem Mag? I have a Ruger #1 barrel in Rem Mag doing nothing..not sure if you could set the barrel back a thread on the No. 1
The 7mm PRC is quite a bit shorter than the 7mm Remington Magnum, 2.28 inches versus 2.5 inches, so no, a 7mm PRC reamer won't "clean up" the 7 RM chamber after setting the barrel back one thread.
