Mike, our differing opinions of efficacy and conservation may be a generational thing. It would be unconscionable for me and those I gun with to wait for a pheasant or any bird to get 25 yards away before shooting at it. We prefer birds within 25 yards, jinking and flaring, for sporting and effective shooting. Slow and deliberate shooting, arbitrarily riding out a bird, is as good a way I can think of for losing it.
