I had an SVT-40 once that came straight form the cosmoline. When I cleaned it from the bore it was pristine as I would expect. I was at a gun show recently where I seen several SVT-40's, some still in cosmoline and some cleaned out. Most of the de-greased ones had horribly corroded bores, I assume it was that they weren't properly cleaned form the last owner, (not the Russian solder form WW2, smartasses) after using corrosive primed ammo. I spoke to one dealer who said that not all of them have good bores right out of the grease. I'm just curious, have some people bought some of the "arsenal re-ferds" cleaned the grease out only to find a parts-gun-grade bore?
