Update: I am glad I have my AR15 SP1 carbine clone (1/7 twist 6420 barrel) with the 4X handy. Yesterday the next door neighbor saw a mountain lion in my creek bottom. We have horses, dogs, and small grandkids here, so if he comes any closer, he'll being eating a MK262 MOd1 77 grain SMK OTM up his @ss. With 150 yards max, I think it is a tad far for an iron sighted M1Carbine.
Lots of livestock attacks in our county (we live in the Sierra Nevada Foothills) and some recent very close calls with humans. I'm on Search and Rescue, and its possible one or two of our missing hikers fell prey to the swarm of big cats we have here lately. This month a neighbors dog was just eaten by a lion, and a friend had a lion kill a deer 50 feet from her back door just last week.
