only luck I've had shooting snowshoes (without a dog) is unused roads and sniping them from a good distance in the head.
We haven't had strong snowshoe population like when I was a kid, snowshoe's were everywhere! Now there is just a few here and there.
Buddy had a yellow lab that got us a lot of hare, he'd bust them and get em moving and we'd blast them when they ran across the road. Then he'd bring it right too us in typical lab fashion.
Makes me question beagles
