When I fired it, the cases looked just like yours [bulged]. The chamber was cut oversize. How, I don't know. It was offset slightly as well. It was the original AMT barrel, and I thought I'd just replace the barrel with a carbon steel Colt barrel. I ended up trading it for something else before I could get around to it...

Point is, there are barrels with oversize chambers. The how is the mystery...

(I think AMT called it the 'Hardballer'...)
