Decent brass for good price
The only source of brass I've used for my .300blk. Got 1k pc so far and have been happy with each order. Brass is clean and could probably be loaded right out of the bag, but I make sure to check that all primer pockets are trimmed to my own spec anyways. Yes, there's a lot of mixed in converted .223/5.56 but this isn't the cartridge to worry about that kind of thing with imho.
