That's a good point, George. If all your shots are coming within .410 range and you can kill your birds with a .410, fine and dandy. (And if you can hold your fire if they get up beyond .410 range.) When I shot the pheasants I mentioned earlier with a 28ga--which I would not use for wild birds--I was counting on consistently close flushes. Which I got. After flat missing the first bird (and feeling like a real idiot), I then killed the next 27 straight, including a couple doubles. 2 or 3 of the singles did require a 2nd barrel, and the dogs had to help me with 2 or 3 that didn't come down either dead or totally immobile. But I also had a 12ga along, and if I'd been crippling regularly with the 28, I would've switched in a heartbeat.
