I got a new Bowtach Diamond Black Ice and made my first kill this morning. It sat at 65 lbs and shooting a 400 axis arrow with 85 grian thunderheads arrow wieght is 400 grains. At 25 yard the arrow blowed through her fast and stuck in the ground about 6 to 7 inch and only went about 50 yards. I realy like my new Black Ice fast, quit and easy to shoot.
