Everyone should have the skills to make their own ammo IMO. It ain’t rocket science, it saves money, and can allow one to be self-sufficient when government actors pass unconstitutional laws. What is the downside?
I plan to be in on the early-side of the Civil War, and use up all my ammo then. I have enough to make some considerable trouble.
The old straight-walled cartridges, at least, can literally be hand-loaded with nothing but a measure, strong hands, and a pocket knife. Makes me want to get an old lever gun (the newly manufactured ones are crap) and a single-six both in 45lc. I am a cowboy, after all, even though nobody but me knows it.
We did a cost analysis on whether to reload or buy and it was a wash.
And have the ability to cast bullets. For old fashioned weapons. Everyone should have a 30 caliber bullet mold. You can shoot them in 30-30, 30-06 & 308; the accuracy can be very good. With a gas check you can load some pretty respectable loads very cheaply.
Same can be said for cast pistol bullets. 38 & 357 158gr bullet mold is excellent choice.
A lighter 105 gr .358 bullet mold can be used for 9mm, 380, 38 spl, 357 mag pistols. Not always the ideal weight, but will shoot in them all.
