When I shoot my BSS in S x S competition events I premount it, same as I do my O/U comp gun. I won the AA class in the S x S event in 2010 at the U. S. Open with it. I had just gotten the gun and hadn't even opened the choke yet on the left barrel. It was still full choke.

When I shoot ducks I mount it and shoot in one motion. A gun does not have to be mutually exclusive of one or the other. You can shoot both ways with the same gun.
