Most of the crippling I've witnessed involves shooting at birds either out-of-range or at a distance the hunter is not capable of figuring the proper lead. If you can't hit a clays crosser at 50 yards, how do you think you can hit a pheasant at that distance? I don't hunt as much WIA or GMA's as I used to, but saw a lot of hunters shooting at any rooster that gets up in front of them, even it its 60 yards or more. The problem is a lack of discipline. The same logic applies to those shooting sub gauges. I hear the 28 shooters telling me how far out they kill birds with their pea shooters, but never how many birds get wounded and lost. Dirty Harry said; "A man's got to know his limitations". Those are great rules to live by, and especially when it comes to cleanly taking the birds. Hunting in the bitter cold/snow/wind last week in ND made me glad I had a 12 ga. No lost birds, and no shots taken over 35 yards.
