I chronographed 4 different ammo's about 2 years ago. All were rated at 3240 fps and most of my results were in the 3000 fps average from my 16 inch bull barrel. Roughly 7% less then the 26 in. barrel used for factory testing. At the time I was only able to shoot to 200 yards and with my 100 yard zero still managed a sub 2 inch group at 200 yards. I have at numerous other times shot my Nikon M-223 3-12 Rapid Action Turret scope and rifle combo to 600 yards with consistant hits on 10 inch steel plates. There's even been a few coyote's out there who would agree this combo works well together.
