I started shooting doves in the late 50's. There have been many improvements in shells over that period of time. When I started modified was the best choke; the boys from 40's and 50's were still shooting fulls. I think they were taking it a step too far even then.
When shot collars came along, I think. you could come down one choke, and I was a pretty, fair, dove shot. We shot at least 2 days a week.
Modified is still a good choke, but Imp. Cyl. will get me a better percentage today. It will kill doves out to 50 yards and leads get too hard to figure after that. We did not use premium shells, couldn't afford them, but the cheapo "dove loads" I had to finish off MANY more birds when shooting 8's than I did with 7 1/2's.
