Many moons ago I used an Ithaca Mag10 for waterfowl and loaded my own shells. I had the idea of practicing with it on doves before duck season so I loaded up a couple boxes of #8 shot. This shotgun had a fixed full choke. When the first dove/victim that came by about 40 yards i swung on ot and fired. You could see the ball of shot heading on an intercept course with the dove and the next thing you saw upon impast was the shot turning into a ball of feathers! I scratched that idea.
