RE: Beretta customer service sucks
It's not a gunfit issue. I patterned the shotgun from a benchrest. I do know enough about gun fit to know I should not have to look at the rib sloping more uphill than any regular trap gun I've ever fired. It's a screwup with the gun. I've fired more shotguns rounds in one year than most pure hunters will in a lifetime. The gun is just off.
It wouldn't be impossible for the threads to be that much off. It doesn't take much to throw the pattern off. I can live with a gun that patterns slightly high, in fact many do from the factory, but not that much low.
