Instead of waiting for a supplier, try downloading some gunsmith e-books
and learn to MAKE your own guns and ammo. Even hollow-points can be
made at home out of fairly reasonably-priced metal-casting gear. Depending
upon your city, state, provincial or national statutes, certain type of guns and
ammo are allowed to be made at home. '22's or .223's shouldn't be a problem
in most states. Go for simplicity and older age...try a late 1930's and 1940's
rifle design but have it fire the 22's or .223's. A cheaper lathe machine and
ammo metal casting system can be had for less than $3000.00 to $4000.00
You can be up and running with some experimentation in about 6 to 8 months
at 1.5 to 2 hours per day 4 days a week of your spare time. It's just a thought
that you might want to consider AND if and when the SHTF comes, being able
to have THAT gunsmith and ammo casting machinery and skillset is well worth
its weight in gold!
One thing I've been experimenting on a very preliminary basis,
is designing REPLICA custom 1700's to 1800's era muskets
and flintlocks on a 3D-CAD system and making them out of
aluminum (casting and machining). Since most aluminum
won't take the firing pressures, these are going to be for
display, but they will look real enough on the wall.
One project I've had ongoing for YEARS (5+) is designing a
SEMI-PORTABLE coil-based rail-gun using home-made ultra-fast
charging ULTRA-CAPACITORS to fire stainless steel rods
that have a magnetic ferrous core using linear induction
as the firing system.
The thing with 3D-CAD/CAM design and machining that
i've found, is that my DESIGNED performance levels don't
seem to match the real-world results.
On a 20 metre rail-gun, I can get over 3000KPH (1800 MPH)
for the projectile in the real-world, but the CAD/CAM design
calculations SAY it should be doing 20,000+ KPH (12,000 MPH)
even with the aerodynamic friction taking place and other factors.
Rod shape, spacing of coils, coil EM pulse flow/ebb are
all factors that still need to be worked on in terms of computer
modelling and rendering of rail-gun projectile and EM coil dynamics
which unfortunately takes TIME, of which I am already so short of!
My next experiment is to go with much heavier gauge EM coils
and use pulses of Really High Voltage DC that deliver 750+ joules
of kinetic energy to the round. Using more EM coil pulse-stages,
and greater CURRENT and VOLTAGE I should be able
to get 2000 to 3000 joules of Kinetic Energy to the round
but that's a whole 'nuther ball-o-wax of brainstorming
time and energy so it actually DOES FIRE a round
at 20,000KPH (12,000 MPH or Mach 18!) or more!
