My sisters barn is currently occupied by hundreds of rats and mice. I sat out there this afternoon with my Henry and a red light and went to work. Originally I borrowed her pink red rider but when I'd pick it up to shoot one the BBs would rattle and the varmin would run off, after 10 or so failures I made the switch. Shot 11 times, killed 10 rats/mice, had to shoot one twice. I'd say it was impressive but it's hard to miss with #12 rat shot inside of 15 feet. I'll definitely be back with more ammo next time.
