Greeting all,
I've been mutely enjoying this forum for quite a while now, and thought it about time to pitch in.
My current "grab n' go" is a folding stock 10/22 with Zephyr peep sights. Light, handy, accurate, reliable (with right ammo), and the fodder is easy to stow (30+ extra rounds fit in the pistol grip compartment). It has both a low acoustic as well as "political" signature. If extra stealth is required, hand-cycling with CB Longs works quite well. Replacement parts are readily available, too. 300+ rounds of .22LR is not too much to lug around, either.
My next project is just starting... I'm building up an NEF HandiRifle System. I've got a .308 Heavy barrel on it now, with a shotgun EER scope coming soon. The scope will allow low mounting forward of the external hammer, and avoid any "eyebrow splicing" should I inadvertantly creep up on the stock. I will add barrels in .223 (with a .22rf insert for small game/quiet times) and 20ga. It already has the "Survivor" storage stock on it, and while not my first pick in fit or comfort, it has one SERIOUS cargo-bay (in addition to a butt-cuff for nine FAST rounds). Ten rounds of .308 fit in the forearm with room to spare, and the butt-stock can swallow boo-coo extra ammo, firestarters, compass (even a small GPS!), cleaning kit, spare parts (if you like, even a Lee Loader and extra components & powder!-what the heck, toss in a whisky flask-that'd make a dandy trade item!). Yes, you could go overboard pretty easily when loading this beast up, but the forearm storage actually allows you to trim out a significant load.
Abiding by the limits imposed of "one gun and 300+ rounds", I could carry the two extra barrels for a fraction of the weight of entire additional firearms. Ammo split might be something like:
.22rf - 120 rounds
.223 - 100 rounds
.308 - 50 rounds
20ga. - 30 rounds
Stow all this in a case only 24" long and you're set to go nearly anywhere, and for a good little while, too.
Result: a single reliable and rugged action that handles .22rf, .223, .308, and 20ga. in an inexpensive but accurate package. Hey, that works for me.
