After fifty some odd years of doing this stuff, I've come to the conclusion that if the average shotgun looney spent as much time shooting as they do agonizing over a few insignificant thousanths of an inch choke constriction, they would be happier. Most shoot too much choke as it is. Choke standards were set long ago, when shotgun cartridge engineering was still in the dark ages, so to speak. My big epiphany came back in the seventies, when I started using my 20 inch Ithaca slug gun (cylinder bore) for birds as well. I killed a truck load of birds and early season ducks with that gun.
