Thread: Borescope images

I had a 6.5-06 that had the screw hole for the rear sight drilled through into the barrel (whoops) and it still shot superbly - 50mm 10 shot groups at 300m in competition were not uncommon. Of course, AR15's have a hole deliberately drilled into the barrel, and they can be tuned to extreme levels of accuracy - what I am trying to say is that a hole, some pitting or surface imperfections aren't necessarily the end of the world accuracy wise.

If it was mine I'd clean it back to bare metal with an abrasive on a patch, shoot it and see what I had. Consistent, repeatable accuracy is more important than borescope photos.
