Gunsmithing scratched chamber question

[42769vette]

ive been offered a barreled action that has a issue. the remington 700 300 winny chamber has a scratch that can be seen in a bore scope. its causing rough extraction and dented brass. the scratch is on the body of the case near the belt but not on the belt

can i get a reamer and barley clean it up by hand and not mess up the head space?

No. By the time you clean up the scratch the head space will be to long.

Re: scratched chamber question

Sounds like a serious "scratch"..

No, you won't be able to just retouch the chamber without opening up HS. However, if you have access to a lathe, youll be able to skim the face of the tenon and barrel shoulder pretty easy, once you cut the chamber a little.

Think of it as a mini barrel setback.
