I love my Stoeger 2000 and have had your problem once. Went and read up on it and found that you have
to use the right ammo. No handicapped or reduce recoil. Mine will shoot the Federal field and trap loads all day long. Switch to Remington and it will not feed or cycle.
When hunting in the field with turkey and waterfowl loads I have never once had a problem. I have fell in the river when it was 10* and the gun had ice all over it. Still ran like a champ. Took it out on Monday for a dove hunt and again on Tuesday for a goose hunt. Great guns!
