I have a J Stevens 12ga. 94A single shot and after reading your post I checked my barrel and it appears to be in good shape. I can see it going both ways to tell you the truth. Too much steel or manufacturers defect. Just out of curiosity, how does the inside of the barrel look? At any rate, if you intend to fire it again I'd get a reputable gunny to take a look at it before I did.
