View Full Version : "Dark" bores
September 11, 2000, 01:59 PM
My recently aquired WWII Mauser has a bore that has no accumulated "crud" but no matter how many times I scrub it with my bronze brush, patches and MPro7, it remains very dark. What causes a bore to turn very dark and why does it not seem to want to be bright again? Is it safe to shoot a rifle with a very dark bore?

It's perfectly safe, lots of old rifles have dark bores. It's corrosion from corrossive ammo. As long as it shoots accurately, there's no reason to be considering a new barrel. One problem with a dark bore is it's a bit rougher than a bright bore, so it'll foul a bit quicker.

Get a Brownells fire lapping kit and clean the bore up.Will smooth it out make it look better and be more accurate.

TMB2, some of the most accurate shooting surplus rifles I've ever seen had sewer pipes for bores. George

George is right. I got a 39 Turk and the barrel looks like somebody crapped in it but it shoots great...not bad for less than $50.
