Well,
I have a few rimfires, but the only semi that I have left is a 15yr old 10/22. After I bought it I was at Shilen on a Sunday when they were testing 10/22 barrels in the shop. I was lucky to get the best test barrel. They said they couldn't sell a test barrel to the general public and offered it to me at a very very good price. I was also able to buy one of the few Jewell 10/22 triggers. I changed out the stock and did some shimming of the trigger housing, changed the extractor and firing pin. It shoots very well. Don't use it much any more.
