Hello everyone I have a Sears & Roebuck semi auto 20 ga ted williams series. I am having a few issues with it. A. I can only get two rounds to go into the tube mag B. It wont feed a round in to the chamber from the mag after I maually moved the action (pull back and release the bolt) C. I know Sears stoped producing guns in the 70's but I know nothing more about this gun. Any help will be greatly appriciated thanks.
