Interesting yes Jack, but they are talking bunker chokes. I suspect that the double trap shooters are using something different. Perhaps T. Baber can shed some light on what those figures may be. The international game certainly is growing in this country mainly to the help from Midway. They are to be commended for they're giving back to the shooting sports.
Thank you SW for your info. I had suspected there might be a significant difference in the two. By your answer it appears he must shoot both games. Good for him and good luck to you and your family. Enjoy, Bob
