Default What does bore is dark, bright, white, etc., mean?

Greetings folks,

I have no idea what they mean. I did a forum search without success so I thought I would reach out to the experts!


Thanks!

Its just a generic condition description.

If you look down the bore and its shiny and reflective, that's perceived to be good. If the bore is dark, frosted over, no-so-shiny, that's perceived to be bad.

Worst of all is if you see pitting in the bore.

But collectors of milsurps have to come to terms with the fact that these barrels are 75+ years old, and bore condition can't be expected to be perfect and original forever.

If the description is on a CMP hang tag…it basically means it was observed as bright or dark. They don’t have time to clean every rifle bore, so they inspect and report. Many times the dark bore is from firing blanks, and the bore will clean up with a little elbow grease.

Too add to the discussion: You mention white, a chamber "in the white," is referring to it not showing signs of being blued or parked. Typically an original barrel that has not be reparked is going to more desirable to a collector. There are exception to that as Winchester M1s had chambers that were parked in some/most/all(?) cases.

I list guns for shop on gun broker. Here is our terms. Consider these stages of corrosion. Worst to best.
Bore is dark=Sewer pipe
Bore is dark with visible rifling.
Strong rifling dark grooves.
Frosted
Bright bore.

Light pits will cause dark appearance. Usually starts in grooves. Frost is tiny pits throughout. Yes this can be caused by blanks.........don't count your chickens that it will clean up.
