Survival Guns! Well, depends on what your need to survive!
'Survival Guns' is a great read, think I got it when it first came out...but according to Mel, the average 'survival arsenal' was large and bulky, with many redundancies...and that did not include ammo, holsters, the years supply of food, a gun safe to keep them in and a large truck to transport all your goodies to your 'retreat'
And too, if this is after some SHTF scenerio, game is gonna be REAL scarce! The most common and dangerous critter running around has two legs and thinks(I have seen the enemy and it is US!!).
I, at one time, thought the shotgun with its incredible versatility was King of the survival guns...but ammo is bulky and very heavy and ranges are short.
Then,I liked the 308 Battle rifle as a general purpose all arounder....but it ran into the ammo, bulk equasion too.
One of the best for harvesting game and general survival duties is and will always be the lowly .22. A brick of ammo takes up no room and the report is small so you will not attract as much attention of the hungry hordes. And in a pinch, it can tag larger critters and serve as an emergy defensive tool.
The various entries from Savage in the combo rifle/shotgun format are excellant...and many that do live off the land have nothing more dramatic than a 30-30, 30-06, 303 or 308. Coupled with a good .22 pistol and you have a very good combination here.
Skeeter Skelton wrote an article on 'one gun for survival' and his pick was his 5 inch M27 .357 and some reloading gear. It would do pretty good in that role too!
My, um, battery is very simple, but I am not planning for major stuff, nor am I doing the back to nature 'chop wood, carry water' thing again(been there, done that, lotta work!). At the moment I have handguns, cause that is what I like, primary in the collection is my .45 auto..not not perfect by any stretch of the imagination, but I know it well and very familiar with it and the long distance tragectory of the 230 grain bullet out of it. I have bagged a variety of game with .45's over the years(mainly cause it is what I had at the time) and though limited in range is does have authority when it arrives. And I live in an Urban environment now, so I want a concealable weapon that can do everything I might need done. I have a very accurate .22 too. Spare parts and spare ammo is in my Bug Out Bag.
Perfect survival gun is the one you have with you when it is needed. And the environment and situation you may find yourself in reflect different needs, The urban scenerio with masses of unruly people struggling to survive is far different than the back woods setting,
