I went to buy ammunition and the store had boxes of "Hunting Target Match" ammunition. It's a 50rd white box with a blaze orange sticker on the top, big enough to cover the top and seal off the ends. One side has a sticker specifying bullet weight and caliber, the other has legal statement. The box states that it is made in the usa, but has no address what so ever. The brass is stamped PMI. I googled it but can't get any results. What is this?
