I just watched the first episode tonight. It was ok, but I don't know if I will end up watching the whole series. I can see myself getting very bored with it quickly. I did like the shop owner though. Looks like he could be a fun guy to hang with at a range or in the store.
From my experience, you both have the answer to why they banned wolf or russian ammo.
At the ranges I've been to, they sweep up all the brass, sort it, then resell it as reloading components. So rather than sort and toss all the steel-cased, why not just ban it so shooters will leave even more brass behind?
