Hi all I bought a Ten. Mt. rifle monday it didn't look to bad no rust in the upper part of the barrel that I could see. Started to cleand it this afternoon and about 2/3 down it was in bad shape. so was using some steel wool on it to clean the crud out and I didn't think that I sounded right when the ram rod hit on the bottom started looking into it more and it had a charge of powder in the barrel just goes to show you ya need to look things over close and not take things for granted that they are fine. Also just to ask the berrel is 15/16 across the flats if the berral is bad can it be bored to 54 cal? thanks tom
