I have got a 96 Swede that seems to foul more so than other rifles I have. Right now I am using Butch's and Kroil. It takes a long time to get the barrel clean. Accuracy does not suffer much even when the barrel is dirty. I would like someone to suggest a faster way to clean this 101 yr old barrel and not damage it. Also, what can I do to make the barrel not foul as bad and as fast.
