Went to the range today and a friend of mine who works there gave me a box of Glaser Pow'RBall. He said it was "great SD ammo" but I didn't get a chance to shoot any of it. It's 100gr 9mm JHP with a polymer(?) tip that is supposed to make it feed more like a FMJ round. Looks pretty interesting... just curious if anyone has had any experience with this stuff and how it stacks up to other SD ammo?
