I called CSMC. The answer I received was that he thought that it was 28 or 30 yards.
An online search found statements that Benelli was 25 meters and Beretta was 30 meters.
Krieghoff uses a #4 hanger for trap guns and a #5 for sporting.
They must have a reason for the difference.
I have used my CSMC 21 on tower pheasants at an estimated 30 to 45 yards with awesome results. [#5- 1 oz at 1150 RST-LM&M]
I will be using my CSMC 21 for sporting with the belief that a sxs is the better choice for sporting and that is why I wanna know.
