Ive hunted with the Cutting edge 130s. I took a muley at 374 in Colorado (on the cutting edge website if you want to see it.). I just returned from King City and shot a boar at 600 yards. I believe the bcs as that is what i am calculating to make the shots.
The rifle is a m70w/ a 25 " douglas airgauge. In 270 improved. The 130s fly at 3350 fps.
