I've always wondered if you could reload steel cases by annealing them first.
it can be done, no doubt. (of course i've never actually done it but there's plenty videos out there)
i think the question is whether it's worth it. it seems very slow and labor intensive.
that being said, my rifle has been extensively tested for steel cased ammo (without even realizing I was conducting a test, lol) Ive posted about it before.
if I shoot nothing but steel cased ammo I have no problems, but when I switch to brass without cleaning the chamber first, the brass gets stuck.
I could foresee a situation in WROL where I simply don't have time to clean my rifle. if I expend all my steel stuff and am forced to switch to brass quickly.
hypothetical situation: I am dangerously low on food/supplies and I'm forced to venture out to find the things I need. I only take steel cased ammo so I don't feel bad about leaving the shells behind. I run into trouble and end up having to burn through a bunch of ammo. I manage to slip away from my attackers and beat feet back to my AO. when I get back I quickly re-up with fresh mags packed with brass and within my first few shots I got a case stuck so bad that it needs a cleaning rod to tap it out.
probably a really poorly written story, lol. but hopefully you all see my point. a field cleaning takes me a good few minutes at least. who wants to be sitting there cleaning a chamber when you NEED your rifle NOW?
I'm certainly not dumping on the idea of the OP. it's a badass idea. but like you said TG, you gotta test your rifle so you know exactly whats gonna happen while switching back and forth between steel and brass. you don't want to get caught with your pants down in a volatile environment.
