There ARE a lot of them shooting crossed. I have run into many that were not regulated. IME, when a S x S is not regulated it is usually shooting across, i.e. the left bbl will print too far right, or the right barrel will print to far left. The bore rings don't lie, Mike. They cannot be perfectly round and concentric if the barrels are not straight. Look down the bores of a really clean barrel at them.
I watched a Beretta video awhile back, made at the factory. One of the segments was about a craftsman there who was a barrel straightener. That's all he did, straighten tubes to perfection with a press. Not a barrel curver, but a barrel straightener.

P.S. I agree the barrels are angled, in relation to each other, and the angles are different on different guns. But, they are angled without being curved individually.

The O/U hangar Kreighoffs have hangars that adjust the vertical point of impact from one barrel to the other. If you want the POI the bottom barrel to move up you put in a shorter hanger. If you want the POI to move down you put in a longer hangar. Adjusting POI by curving the barrels does not require a press.
