I actually prefer buckshot on drives and in the swamp. Inside 35 yards if you aim for the chest you will more than likely knock the deer down on the spot. If you try to hit the head you stand a good chance of knocking off the bottom jaw or something. You can't ever get rifle performance out of buckshot, but that isn't the idea behind buckshot. Use it like a shotgun, on game inside 35 yards, often moving, and I don't think there is a better choice.
It's like bow hunting in a way. You need to know how your gun patterns. You need to be in closer than with a rifle, and you need to aim for something big enough to hit without stretching your luck, like the chest.
Just my opinion though.
