Fek knows then! I have reloaded a fair old bit of mil .223 brass (TZZ, RG, JG, CJ, LC currently on the shelf) and and it is
A: Heavy and very low capacity compared the the Hornady stuff I use and
B: Crap
I can get 28.5 gn of 2206H into the Horny stuff and about 26 gn into most mil - that seems to me like it has less internal capacity or something? No doubt the internet will prove me wrong though
As above, unless you are broke or need to for some unknown reason just buy good brass and never think about it! 7/08 cases should get 10+ loads or more if you anneal once in a blue moon. 100 cases will last a fair old while of normal shooting (or just buy 50 Noslers or similar). I understand the appeal of using what you have and putting that big bag of brass to use etc, however often having lots of cases sounds good but means you easily get into the mess of having cases with an unknown number of firings / trim length / neck sized or full etc etc. Its easier to "only" have 50 or 100 and keep track of them.
