It is good stuff, it is just reboxed Winchester Ranger SXT ammo. They are marketing the PDX towards civillians since they frown on marketing the SXT to the public. I always pick up boxes of Ranger SXT at the funshow. It is about 40 bucks for 50 rounds.
I shot some through my SIG1911 and its the only factory ammo that I've fired that will fire 1.5 inch groups at 25 yards. Im not saying that I;ve tried alot of ammo, but I dont need to now. This stuff is very accurate in my 1911.
