Watched a fellow at a columbaire event shooting practice birds with a nice Model 21....he wasn't missing either. When it came time for the 10 bird race, he pulled out an O/U and I asked him why he wasn't shooting the 21 since he obviously shot it well. He replied the gun wasn't ready for serious competition yet; the stock had to be converted to an adjustable comb and the barrels ported. I could have shot him.
