As a gunsmith, 'Preppers' are a never ending source of income.
That should tell you something about 'Prepper Ways' of doing things...
Barrels so leaded you can't find the rifling, lead in gas systems, brass carved up so bad they can't get it out of the chamber...
You CAN make your own black powder, I tried it ONCE... I'd use a bow & arrow rather than go through that again!
You can forget trying to make high velocity powder.
The biggest waste of time I've ever seen is trying to recycle primers!
7/10 won't work and the ones that do often squib, nothing like ejecting 6 rounds just in time to beat the bullet out of the barrel on the 7th...
'Preppers' ALWAYS do things the hardest and/or most expensive way for some reason.
I got to go with Mr. Morris on this one, if it's 'Prepper' stockpile, there is loaded ammo WAY cheaper than you can buy first quality components & build the ammo.
Keep in mind, it's actually just as easy (maybe even easier) to store loaded ammo than components.
The cheap China & Russian ammo is abundant & cheap again, while quality US made components are available, but not 'Cheap' and there is labor & loading equipment to be considered...
I buy milbrass 1/2-1 MILLION at a time, once cleaned (slow), I can process at 700-900 an hour.
Done correctly with first quality components I can crank out 1 MOA (+/-) ammo at around 700 an hour.
This is with $10,000 worth of equipment.
How much ammo can you buy with $10,000 and never touch a reloader, your labor consists of moving from cardboard boxes to ammo cans...

I agree, learning with known, first quality components is most certainly the way to go.
You won't find loads in the manual for 'Traded Powder' or 'Recycled Primers', go with high quality components so you get the PROCESS correct, and you learn things like pressure signs.
Cranking out a case that fits the chamber *SOUNDS* simple, but you would be surprised how many screw that up on a regular basis, particularly if they are loading ammo for more than one firearm.
I STRONGLY suggest you get a manual index press, either a single die press, or something like a Lee 'Turret' (tool head, 3 or 4 dies you can rotate in a tool head) and learn the 'Slow' way of doing things.
Once you develop a process that excludes the possibility of no charge/double charge, and can produce a useable round, then work up to volume.
There are a TON of mistakes you want to work out before you try and produce a reasonable 'Standard' round... Getting in a hurry makes things 10 times more complicated.
DO NOT try to load to any 'Maximum' right off the bat!
You will find that most rifles function better when not loaded to Max, and even more find accuracy nodes BELOW the Maximum published charge weight.

If you want to stockpile for cheap, try pulled bullets.
A 'Soft' bullet, copper over lead core, can be pretty screwed up and still be 'Safe' to shoot.
Keep in mind, anything in front of the 'Ogive' doesn't really matter since it doesn't contact the bore.
People load bullets backwards in the cases and they still 'Shoot', so the point can be missing and the bullet still 'Shoot'.
(Ogive, the point on the bullet where it gets large enough to contact the bore)
Most pulled bullets will show pull marks, but they are fine to shoot, not many will be seriously mangled.
Pulled bullets are WAY below scrap weight since they are mixed metals, but be prepared to buy 10,000 at a time.
They won't cost much, but consider what 10,000 bullets weigh before you buy.
Some lots of pulled bullets can easily be 50,000 to 500,000, so be ready for that and check the weight before you buy...
For instance,
55 grain FMJ, military standard bullets, around 127 to the pound,
2,000/2,500 pounds in a bulk bin isn't uncommon.
2,000 pounds is about 254,000 bullets. (Bring friends!)
The bad news is several dozen to several hundred pounds at a time, the good news, 10 to 30 cents a pound. That's cents, not dollars.
Pulled powder is pretty cheap also, I don't mess with it but there is a lot of it available.
Keep in mind to buy pulled powder, you WILL have to clear a government background check...
Which, in typical government style, takes 6-8 weeks.
Be careful when you work your loads up, sometimes it's mixed powder so you want to check/work up when you open a new jug.
I've heard horror stories, never actually seen it since I don't use pulled powder.
This is going to sound crazy, so bolt yourself down...
Brass comes out of the tear down process with the primer intact sometimes, but don't assume decommissioned brass will still have the primer in place, check the lot before you buy it.
Useable brass takes a government background check, again 6-8 weeks.
If the primers are in place, the first thing you want to do is dry them out.
Food dehydrator for a few hours usually does the trick.
Test several, simply chamber the brass and let the firing pin hit it.
If they all fire, they are probably dry and will work.
Military primers are a little 'Hard' when compared to civilian primers, but they are also hot enough to ignite about all powders.
I've seen people put primed cases in the oven! I don't recommend this for obvious reasons!
I've never used a decommissioned primer, and never will. I won't even consider a primer that's been installed then punched back out.
I've seen them, the decommissioned primers are virtually free, I still won't use them.
