We had doves at 10 and 15 yards and the Minishells were lethal at that distance. I’ve shot a few doves with them since, and in general I’d say they are good for small birds out to 20 yards although I’ve made a few longer shots. On clay targets, which do not suffer when inadequately shot, Minishells can be effective at much longer ranges. The other night I broke 24 straight trap targets from the 16-yard line with them, then got so excited I was about to shoot a 25 straight with Minishells that I spaced off the last bird, then broke another with my extra shell to go 25x26. I also broke birds easily from as far back as the 21, which meaning the shots were up to 35 yards from the muzzle. Minishells are quiet, recoiless, and plain fun to shoot. They’re instructive, too, as the absence of recoil lets you see exactly what happened the instant the gun went off.
