DUH!!! Cannot believe that I didn't try and ring the barrels first thing.....like bells! both tubes sounding identical, and that is on a gun with a forearm lug repair! I brought the barrels with me to the office today, and after ringing them, took a dental scaler and was able to scrape whatever this is, (definitely metallic) off of the surface of the tube....SO I got my cordless drill, a rod and jag, a frontier pad and some ballistol, (everyone has those in his or her office right) and went to work. The crack is gone!!!! AMAZING!! I still cannot believe that the bore snake, and it was a fresh one, with an aggressive brass brush on it, did not phase this thing!
SO my most sincere and humble apologies my sensationalism!!! But, I am so happy this gun was not ruined, it is an early gun ser. # 2254.
Thanks for all of the input, especially those that doubted a crack!
