Military cases can also be Berdan primed (two flash holes inbuilt anvil) as opposed to Boxer Primed (one flash hole no built in anvil).
Centerfire ammunition - Wikipedia, the free encyclopedia
If you miss even one "Berdan Primed Case" you will break your decapping pin.
That said I use military brass all the time for reloading and have never had any issues except for the above.
I dont reload any Berdan Primed cases but have done so in the past and know of people who still do.
Cheers
