I have an Ithaca SXS circa late 1924 from the serial number. It was given to me 50 years ago and I have hunted, shot trap, skeet and sporting clays with it. In the Spring 2013 I had a problem breaking the breech after firing a round, single or both barrels. Took it to our local gunsmith who could find nothing wrong other than firing pin areas were very dirty. Went back on the range, same problem. Second gunsmith, could find nothing wrong. I am aware of articles about todays higher pressure loads and this era Ithaca SxS. Had it checked for barrel and receiver issues, again nothing. Any suggestions? P.S. I live in South West Virginia near Bristol, a good gunsmith referral would be appreciated. Thanks
