I think Amarillo Mike slurred my Dawgs, but it's hard to tell cuz he talks so uppity. My favorite Pheasant gun, an "FE" 16 bore Lefever is choked IC and Full according to Mr. Buck Hamlin. Seems to work well. My 2nd go to gun, a "G" Lefever is choked Cyl-IC. I didnt know that until Joe Wood went and measured it at Raton a couple of years ago. I regularly shoot sporting clays with that gun, and bust stuff way out there. I have to say, I dont understand the compulsion to plan on changing chokes in guns that havnt even been bought yet, or shot much. I shoot an "E" 10 bore Lefever a lot during the bird season, its heavy enough, and my reflexes have gotten slow enough that I dont have to do much whistling before the shot...I never change chokes on anything, learn how it shoots , and then shoot it...
