I don't know what the best measurements are for skeet. However, the best shooter in our club in 1964 shot a Browning O/U trap gun he had sawed 2" off the barrels removing any choke. I was horrified watching this work as I couldn't conceive such a desecration of a gun I couldn't afford. The barrels weren't even square or smooth having been cut with hacksaw and coarse file. So cylinder bore was not a handicap at all. This statement would be relatively meaningless except that our shooters included skeet legend Al Buntrock who shot a Remington 1100 Skeet gun at the time. The best shooter wasn't eligible for the Olympics as he was a professional having shot live pigeon in Europe, sponsored by AYA if I recall correctly, making about 20 times his Army pay in his spare time.
