[ARCHIVED THREAD] - WTK Frotsting in a barrel?

WTK When it is described that there is light frosting in the barrel.

What does this mean?

I am not familiar with this term.

Any info would be helpful before next possible purchase.

THANKS!!

You know how your windshield looks after a frost during the night? It sort of looks that way inside the barrel. Bright but not smooth, almost like the inside of the barrel has a light coating of frost on it. It is sort of a step above a bore that is rusted and dark when looking through it. I guess the frosting is sort of a lightly rusted bore that has taken off the polished look but not so bad as to have pits in it to make it look dark and obviously pitted.

That is a good way to describe frosting.

THANKS for the info!

Based on what I believe your saying, I guess I should be cautious of a barrel that is frosted.

Thanks again.

Not necessarily.

I have a Russian capture German K98k Mauser that has a dark frosted bore, however it groups quite well.

Good point, I have a Russian 91/30 sniper that has a very ugly bore but will shoot under 2" at 100 yards. Hard to believe. Pretty touch old rifles...

"frosting" seems to usually begin in the grooves, so light frosting should have minimal effect on accuracy. rust on the lands seems to be pretty bad for accuracy, though. sometimes barrels can take a curious amount of damage before they suffer loss of accuracy, so the only way to know is to shoot it.

No kidding. I've had a few milsurps with barrels that looked like gravel driveways they were pitted so bad, yet they still shot acceptable groups of ~4" at 100yds with surplus ammo. I wouldn't sweat a frosted bore. It will more than likely still shoot fine.
The main problem with corroded bores is that they don't clean up as easily. One thing you can do that has worked for me on several rifles is to lap the bore to polish out most of the roughness. YMMV
