Good ammo. There are certain calibers I would use DoubleTap for (10mm), but 9mm and 45acp aren't among them. There's plenty of other equally capable 9mm options from the major manufacturers for way less. If you want high pressure, this stuff will hang with anything similar from DoubleTap. It's 127gr, 1250+fps, $25-27/box.
What recipe were you ordering that prompted you to choose DTap?
