[QUOTE="Trickymissfit, post: 1304527, member: 25383"] I doubt a dull reamer would do that much, and a dull reamer often leaves a better finish. Like JE stated, it looks like the wrong spindle speed, and an idiot cutting the chamber. The dead give away here is that there is not just a couple of lines on the surface, but just about one for every flute. This tells me two things right away. Lack of lube on the cutting area of the reamer and the flutes probably quit cutting because they were so loaded up with shavings. Probably used the wrong cutting fluid as well. What I would do; is to send it back and ask for a complete refund. Of course they'll say no! Your best bet is to do a .38" barrel setback, and recut the chamber by hand using a rough cut reamer and then removing the last .005" by hand. Keep the reamer clean, and keep your cutting fluid as clean as possible. Dirty cutting fluid leaves marks as well. gary [/QUOTE]
