.22/12ga duct taped together, try shooting that and actually hitting what you aim at...
i didn't say
duct tape -
you did. plenty of other ways to do it acceptably.
my cousin did this when we were kids, before we knew it was illegal
(IIRC) - it worked great. just a little stock furniture work involved, and some practice patterning the shotgun. i think it's a decent concept. especially if you are handy with wood and composites. add some JB Waterweld
(or homemade resin if it gets that bad) to the solution and
fuggedabouddit. What happens if the emergency lasts more than 120 days, how are you going to replace that ammo you shoot up?
too many ways to go into, to solve that dilemma.
if i can't figure out how to get more ammo, i won't make it to the end of the
"120 days" anyways, i reckon.
Trade what to who? Maybe they'll try to take what you have, now you have less ammo.
i'm not that paranoid.
6 ways in, twelve ways out, so to speak.
i also have no idea why i'd run out of 22 ammo
(not to mention 12 gauge) in 120 days
(where the situation actually would produce game AND i'd be allowed to hunt it with a firearm of all things), short of ongoing battle. - if i could hunt, i'd probably be missing three rounds from shooting cantankerous racoons and coyotes in traps, or maybe popping a two-leg here and there that was out of proper hawk range, ...and the 997 other rounds would be sitting there gathering dust.
And FMJ isn't all that great for hunting.
not sure where you got the FMJ from.
bow and arrows seem to be sliding out of favor lately too, for lack of perceived takedown; - 'seems like a sophist argument to me, flying in the face of most of human history, as well as my entire relatively-gun-deprived boyhood eating birds, turtles and armadillos.
...and then there are
slingshots with tiny 6mm ball bearings, which have taken everything i'd be likely to trap in an extended dilemma - coons, birds, racoons, cats, dogs, yotes....
not to mention that you won't be able to conceal carry a classic flintlock too easily, if it comes to that. - not with a 36" - 48" barrel.
at any rate - FMJ works pretty well on skulls and oblique hits IME.
you are right, it's not perfect, but not bad either. really pretty good when killing trapped animals though IME. contacts shots make it even better, due to increased cavitation - if you choose to go that route, using your long arm as part of a trap.
tag close to the CNS with FMJ and go in there and club whatever it is while it's wiggling, and you have a lot more good fur.
false argument still though, i feel - bring better bullets.
yer done. This is not for defense, although it will work, once, but as a hunting weapon, it lets you save your cartridges for desperate situations.
but you are carrying
all that lead and support gear for a large caliber firearm, is my concern - and now you are
also carrying conventional firearms in your scenario - dubious propostion IMHO becasue the
pounds and volume are ticking upward,
especially when ya gotta move afoote, and not return. let's see the
weights of what you are going to carry - plus your level of fitness!-
weight per value, i think .22 LR is a better deal. - traps and a bow will do the rest - and if it was
really an extended emergency, i wouldn't bet on game being around anyways. hunting to survive just seems silly to me. - so you are back to needing that primary firearm as a repeater for defense, or at least something with a lot of reach compared to a fliintlock.
good luck though, and most importantly - take pride in the things you have conviction with.
and maybe watch out for getting sniped with .22 FMJ and then hawked after TSHTF, bro. - i hear flintlock folks are paranoid.
i'm kidding.
i kid.
