I'm looking for a steel shot load that retains enough energy for a killing shot, on mallards, at 50 yards. A few years ago I read an article & the writer said #1 shot wouild do it - I don't recall the load size, or the speed, but I'm guessing back then it was probably about 1,400 fps. Since the speed has increased drastically since then, Remington HyperSonic at 1,700 fps, I'm wondering if maybe 1 & 1/2 oz. of #3 shkot would do the trick. Brezny writes on this sometimes in Wildfowl Magazine - wondering if ya'll might know. Thanks.
