the Aguila brass is pretty good but being military spec it has less case capacity so reduce the powder loads by at least 0.5grains
also you'll need a primer pocket crimp remover for this brass.
I found Aguila 7.62 brass to be the worst spec brass I have ever reloaded.
Primer flash holes way off center and very inconsistent case capacity (by lot).
The brass is also very very hard IMHO.
