Even if you could shoot them with that thing and not scatter them into 6 counties, how could you possibly keep track of which ones you've hit and which ones you haven't - most of us have herds that all look pretty much the same! I can't usually tell one from another without getting a look at the #. You'd have to set up in "sniper teams" with a shooter and a spotter!
I think I'll stick with running them through the chute - call me old fashioned!
