Ive only dispatched 2, but they were in my yard and I suspect they were after my puppy. Used 7.62x54R on them. It made a neat 30cal hole on both sides, small mound of dirt where the bullet enters the ground. It was pretty quick, one ran a few yards kind of stiffened up and collapsed didnt see what the other did. I finished them off with my mossy 702 plinkster and threw them in the fire pit. I havent seen one in a while, though sometimes i hear them yipping when they catch a rabbit or squirrel in the adjacent corn fields. I have no more squirrels, my new target is moles when they start poking up through the dirt. I dont eat them, though my cat loved the squirrels and the occasional rabbit.
