So I have been testing several manufacturers of .300 BLK as well as different grain bullets. For the past few weeks I have been testing around 200-300 rounds of this stuff. I will say i am highly impressed with PNW. This is actually a 155GR thats rated at 1990fps. Compared to my hornady 110 and remington 125gr supersonics, this stuff here will likely be my all time usable round. Not quiet as fast at the lighter rounds, but it is more accurate (on paper) and of course it packs a little more punch.
