What brands of ammo would you think twice on stockpiling?

I'll buy almost anything in reloadable brass cases.
I started last year to limit my calibers and get to 1000 rounds each.
.380, 9mm, .45ACP, .223.
These are what I mostly shoot. I replace what I expend, and I don't get below 1000

.22LR is a no-brainer.

I'm not there with 30-30, but it only fits leverguns, not semi-autos, so usage is much less.
Same with .38 spl for revolvers, we just don't use it like we do with SA pistols.
I do have a couple of .32 ACP that I'm not quite up to my goal also, unless you count the plastic ammo ;)

I understand that for some people steel has worked just fine. I will continue to use the ammunition that my gun was designed to use. I find it hard to believe they had steel in mind when they designed and manufactured my guns.
