Couldnt find an answer to this via search so here it goes. Removed the barrel off of my 308, and its was Mike Tyson tight, with what appeared to be lots of blueing salts in the threads. Kind of buggered the barrel nut threads so I ordered a new one. The barrel shank now has one small area where the threads were slightly sharpened or "squezzed" so that barrel nut wont thread on. I think I could knock the edge down with a file, but would I be better of picking up a die to chase them. If so, I understand that the Brownells die might not be the exact correct pitch. What is the general opinion here?

Thanks in advance for you guys input.
