I had a Mod 24 O/U in .22/20 gauge and it wasn't ideal for my uses, which included grouse and woodcock, jump-shooting ducks along small streams and other small game.
The sights were terrible, the .22LR barrel wasn't that accurate and the 20 gauge barrel threw an extra-full pattern. Because it had a rifle barrel, it was illegal for hunting ducks.
I found it was too slow to cock for flushing grouse.
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
