As anyone who shoots knows, it has become pretty hard to get .22 ammo.
Especially CB shorts and longs. And then when you do find some it is
of limited amount and exorbitant cost. So as I was trying to fall
asleep after waking from a hot flash in the middle of the night it
occurred to me that I could make my own .22 centerfire brass, cast my
own bullets, and use off the shelf primers. Checking yesterday for
primer availability I found several sellers with small pistol primers
in stock at less than $30.00 per 1000. That's less than 3 cents per
primer, about what I used to pay before this ammo buying panic and
subsequent gouging started. This morning I examined the bolt on my
Remington model 514 and determined it would be pretty easy to make a
new bolt for centerfire ammo. And most of the parts from the existing
could be used in the new one. I would need to machine cases from solid
brass, but I have a lathe with a bar feed setup that could make them
really fast. Each case would require two operations so I could run the
second operation while the lathe was doing the first operation. I have
never really reloaded ammo before though I did reload a few rounds 45
years ago when a friend's dad showed me how his reloading setup
worked. He let me load a few rounds but I may as well have never done
it before because it was so long ago. But from reading about it online
it appears that spent brass cases can usually be used 4 or 5 times,
and some times even more depending on how light or heavy the load is.
I have lots of pure lead and making a mold would be pretty easy. But
would a machined case be as durable as a formed case? And since the
smallest primers I can find are .175" O.D. and .22 brass is .224" O.D.
there would only be a .0245 wall thickness between the primer and the
case outside. Then again, since the case is trapped in the chamber
maybe that's not a problem. And I would be using black powder or
black powder substitute, not smokeless powder, since my aim is to make
low power quiet ammo for target practice. I have a small revolver and
two rifles that I could convert to centerfire without too much work.
So, am I nut to consider this?
Thanks,

Entirely possible..

Though to be fair..Id use something a bit larger... 222 or .222 Mag,
or .223/5.56, 22-250 and simply make a set of cartridges that have a
tiny powder capacity and then simply push in a .22 pellet from an
airgun. Use a large shotgun primer all by itself and it will launch
that 22 pellet over 800 fps

Know anybody with a CNC lathe? turn out the cartridges from any sort
of bar stock, steel, brass, bronze, even aluminum. Its not rocket
science. They only need to fit in the neck and the base
area..everything else could be undersized with no issue.
