Mix match brass but shoots consistently well.
Ordered 250 rounds and received 250 rounds within a week shipping time. The brass was a mixed bag of Winchester, Federal, pmc, cci, sig, s&b etc. I shot 50 rounds of the Winchester reloads with 0% failure rate. Everything seems to keep a tight accuracy. Took a 100 yard shot and nailed a 4.5" plate. Checked out the round and it was perfectly expanded. Excellent target practice rounds for the price. As for the packaging the rounds are loose packed in the ammo box so there is TONS of metal powder/dust/fragments in the box and covering the last layer of rounds in the box. Luckily I was doing 100% meticulous quality inspection and caught it before running any rounds through my gun. I ended up hand cleaning each round throughly and had to clean the empty ammo box to get rid of the dust. Not something you can just buy and shoot, make sure you inspect everything first and wipe it all down. Some of the brass had serious dent/dings/machine marks that haven't affected performance yet but certainly look like they've been reloaded a few times.
