When I first started shooting skeet- after shooting a few years of trap, I put my O/U barrels on my 686 Silver Pigeon (which is made for doubles trap) and took it to the skeet house to shoot some skeet. Everyone said, "You can't use that!! You'll shoot over the top of all the targets!" I just slid the gun up in my shoulder, aligned the beads and it wasn't long before I was shooting as good as everyone else. Some better. I had watched Tom Knapp do that with a field grade shotgun. He slid the gun down on his shoulder, stacked the beads and shot trap with it. Then he went out to the field and shot the same gun normally and knocked down dove after dove. Plus, those guys didn't realize that when I shot trap, my trap gun was set up with the beads aligned because I like picturing a stationary target. I eventually ended up buying a Citori that I now use for skeet...... Now sporting clays was a different story. I shoot with two or three other guys about 3-4 times a year. I was pretty pathetic. I think the third time I ever shot, I took my Citori and had a pretty good day. I forgot to change my chokes and had cyl/cyl in the gun from shooting skeet. One of the other guys and I both shot a 40 and had the two best rounds. I thought that was pretty good for me. I think it was one of those days where I was just lucky. We usually shoot more than one event during the day...... Most serious trap shooters don't like to change things around. It will mess up your timing. And one lost target could cost you hundreds of dollars if you shoot the calcuttas regularly. My 12 and 20 gauge reloading machines stay the same. If I shoot skeet with a 12 gauge, I might change to #9 shoot. But other than that, I don't like to change things around.
