My .17HMR is by NEF. It IS
just a break-action single shot with a heavy barrel, so rapid "pot-shots" at a runner wouldn't be an option. On the plus sides, I picked it up for a paltry $110, I can get change-out barrels for it in any rimfire caliber they offer, and it's so accurate that shooting the caps off a soda bottle or spent shotgun shells at 150yds has gotten boring. It's a serious "prairie dog sniping rifle."
