A 10/22 is an excellent choice for a "shtf weapon."
I love the 10/22. My main one is a stainless with a grey and black laminated stock. I have NEVER cleaned it, but it works without fail. They are
accurate, virtually indestructible, simple to operate, easy to clean and to get parts for - factory and aftermarket. You can put cheap optics on
them, use some aftermarket peep sights, red dot sights, or upgrade and stick some high-dollar Leupold glass on them. Or just use the factory flip-down
leaf sight. Either way, they are damn accurate.
Magazines are cheap and plentiful.
Other benefits: They are cheap, lightweight, and chambered for the .22 LR cartridge. Folks, the .22 LR is a magnificent invention. You can buy 550
rounds at wal-mart for about 20 bucks. A .50 cal belted ammo can will securely hold 5000 rounds, if they are bricked.
Folks will argue all day an night about this, but you can use .22 bb caps, cb caps, shorts, longs and long rifles in a 10/22. It works...you just
have to finger feed them and manually cycle the bolt. Your .22 cb caps are as quiet (if not quieter than) a suppressed .22 LR, and they hit hard
enough to kill a man at 25 - 30 yards.
Another benefit of the 10/22 concept in an emergency situation: you can very easily make large groups of "zombies" go in the opposite direction. A
.22 LR solid hits HARD. A couple into the torso is an extremely effective fight/riot/looting party stopper. Load up come Remington Yellow Jackets or
CCI Stingers, and you have a very effective assault weapon.
If you have the range, go shoot steel gongs at 200 or 300 yards with a 10/22. You can dope the elevation very easily with even a cheap scope, and
consistently ring a 20 x 12 steel plate at those distances with noteworthy authority. Also, you don't have to pull the rifle down out of recoil to
see where the bullets strike...you just walk them onto where you want them to go.
I've killed lots of big south Georgia whitetail deer during night culls with a 10/22 with Rem Yellow Jackets. You shoot them in the eye sockets or
low in the chest, they either drop like they have had their legs cut out from under them or they run a little bit, drop and die.
Another benefit is that you can get the lighter bolt and spring, with the .17 caliber barrel from midwayusa.com and shoot the tiny little .17 hornady
cartridge. It could give you more velocity and longer range in the same rifle without much labor.
Good luck, be careful and have fun.
