What's the big deal about once fired brass????
I, almost always, use range pick-up, and reformed brass.
Never really had all that many problems with it.
Even with full power loads and condom's.
When they split, it's time to replace.
I've seen new brass, and factory ammo, split.
I just don't understand why once fired is so important.
And how would you know it's once fired, unless you fired it???
