I have a 12ga Flues with a cracked frame that I had repaired. In all fairness, the gun doubled with the old high brass Green Remington paper Express shells. I was about 14 year old. Perhaps I had 2 fingers in the triggers. A broken recoil spring was found when it was inspected. The recoil was so heavy that I was briefly disoriented and thought it had exploded. When I say doubled, both barrels discharged at the same time, not one after the other.

I shoot it occasionally now with 7/8oz low pressure handloads without issues.
