yea, tell that to all the dead ducks weve killed with em. #4 faststeels are all i use and have never had a problem. i rarely ever have a cripple. why is this though?? -- because i only take shots i KNOW i have a very good possibility of making. you have no business taking shots out to 60-70yds, PERIOD! they are definitely not decoying so these are passing shots from that far, youre chances of knocking birds dead is slim no matter what youre shooting. if you can consistantly knock em down from that distance youre a damn good shot. i just dont believe it. i have said it before, people killed many a duck before the days of super fancy camo, 3.5" shells and hevishot so they arent required. money cant make you a good hunter. it can compensate for a lot, but if youre a good hunter and a good shot, you dont need hevishot. if you have to spend that much to kill ducks, i suggest to take a look at how youre hunting (why you cant get birds closer) or take a few trips to the skeet range.
