Stoeger 3500 turkey choke

[Uncle Jesse]

A friend of mine got a 3500 last fall and he brought it out friday afternoon to do some patterning. He had 3 different lead shells that he was going to shoot with the turkey choke that came with the gun and with a Carlson's choke. First 3 shots was with the Stoeger choke, these were the only shots fired through the choke too. Then he tried to unscrew it but the back of the choke had bulged and I didn't think we were going to get it out but we finally did. Has anyone else had this problem?

He shot the same 3 shells with the Carlson's choke and it came out just fine.

Had the exact same problem. Never thought the factory would come out but finally did after about 30 minutes. Hevi choke no issues.

I had a 3500 last year but no issues with Winchester black box. Several rounds with nary an issue.
