Some people reload.
That is irrelevant to this discussion. You can only reload if you can get the components. We're talking about the difficulty in manufacturing the components themselves. Could your average reloader produce primers, smokeless powder, cases, etc. economically from non-regulated materials?
“Some people reload.”
That’s like saying art is easy because you can buy puzzles. Assembling the pieces is trivial; stamping & shaping shells is hard, making primers is hazardous, swaging projectiles (stuffing lead wire into copper tubes and squeezing to shape) isn’t hard but making them accurate & high-performance is, mixing propellant powders is an art, and that’s all assuming you can get the right metals & other specialty materials in forms you can work with.
We’re not talking black powder & lead balls here. “Reloading” amounts to final assembly; yeah it’s cheaper, but when SHTF you’ll wish it were all assembled already and not have time/resources to make more.
