My understanding of survival and yours my be the same or as different as apples and bananas.
In the end if I had to live by my wits (I'm wit challanged as it is) I'd want as much going for me as possible and would want a compact and reliable not to mention robust firearm, to subsist to survive I'd go with a compact hunting arm with good sights and reliable mechanism able to digest any .22lr ammo fed into it (your favorite brand ammo isant alway's availabe in a survival situation) I like semi autos and have had some good ones and I'd have to say they all choke of certain lots and brands fed them.
the most reliable firearm I ever had was a S/L/LR winchester 94/22 leveraction
I like bolt guns but the Idea that that darn bolt could open while climbing through brush and terrain to later on find it had opened and fallen from the action in the last 1/4 mile is a constant deread of mine (Jimny Crickets are bad for this!)
My Taurus 72C-ss is a stainless carbine that is insanely accurate and very packable and locks up like a bank vault and feeds all .22Mag ammo without a hitch, I'm considering getting a .22 S/L/LR version of one these neat little carbines.
Ive used the Remington Nylon 66 (Hard to find &easily broken plastic bolt handle)I like it but it does jamb on certain types ammo so have to clean it and ease of cleaning is a small consideration as well in a survival situation as well dissembling a Ruger10/22 (easily broken rear sight)or a Marlin 60 (muck-a-matic because it seems all the powder residue ends in the trigger group) while hideing out living in a dougout or a tent dosent sound like a activity I'd like to undertake dissembling a firearm for cleaning without a screw driver or even a shop to fall back on.
Since I live in a remote area Ive noticed some the hardest carry worn guns see little fireing the finish is gone the metal pitted and worn away, sights electric taped on, paper wedges for sight elevators, missing rear sights (folding pot metal ones) safeties completely missing, mags missing that drop out while stocking game, front sights that are knocked off the side or completely missing, slings made of boot lace to free hands for climbing and such, extreme cold temps that shatter plastic that is resiliant and robust in more temprate climates, .22's with stamped sheetmetal parts like the cartridge guides on the Marlin 39 replaced -4, Savage Stevens, Marlin stamped spring steel extractors that simply snap off, Adjustable rear sights with small screws that areeasily lost or broken (**** happens) find what works for you, know your guns limitations have a sensable replacement in the butt stock under the butt plate
The only way to learn what you need is use it, hunt with it, and if it comes up short trade it off and get somthing you can use, why house stuff you dont need or use? I know its hard to cull a gun from your equipment but if its a lemon, Why whate for when your Azz is on the line its best to get that out the way before it becomes a survival issue.
