What cases are used in their reloads? Is it all their own cases that have been once fired, or is it a hodge podge of other manufacturers brass?
It is a hodge podge of other manufacturers brass. However, it is good brass, and it is pressure checked for signs of case weakness.
The ammo that I bought (1,000 9mm and 1,000 5.56) has been great so far. I will recommend their blaster line. Even though it says that it is "cosmetically blemished", I had to look closely to see the problem and it still performed fantastically. (And the picture doesn't really do it justice, these cases are actually shinier than they appear in the picture)
They are a great company, and are selling great ammo at a great price. Nothing to not like!
