As always, i got what i paid for, and if i didn't think it was a good deal or trust the service i wouldn't have made the purchase. Probably into the double digits now on orders through Velocity, and they always deliver.

Shot about 250 rounds no problem, love the way the rounds are packaged I can just dump them in my ammo boxes for easy quick storage. Rounds look clean and brass feels nicely polished/smooth.
