For most guys reading this, trying to get a gun to shoot 40 yards well enough to kill a turkey is not going to happen. Most guns will not pattern consistently at 40. I’ve shot a lot of turkey in my life and they are a very tough bird.
Every year I cringe when I hear someone in the distance hunting another bird shoot 3 times. You know they probably didn’t kill that bird. They say “ I missed”.
Well you didn’t miss. You just didn’t kill the bird. You still put a bunch of shot into that bird. I’ve shot turkey late in the season that I wouldn’t eat because someone shot it earlier in the season and it was all festered up. It happens. They deserve better than that. 40 yards is WAY too far for most. Keep your shots at 20 yards and under.
