Hi all,
I've recently brought a second hand Baikal to use as a gun for pigeon decoying and ducks.
Today was the first time I have taken it out, and when I was cleaning it I came across these two black spots in one of the barrels that wont move whatever I try.
Any idea what they are? I'm not too bothered about them - the reason I got the gun in the first place was so that I didn't have to worry about it too much - I am however slightly puzzled by them.
So far I have tried various brass wire brushes, leaving a patch soaked in 009 over it or an hour, general elbow grease etc...
Useless photo I know, but its not the easiest thing to photograph - you can just about make out what I'm going on about though.
Any help would be greatly appriciated
