Took a big doe to feel my first tag with my new go fast Bowtech Black Ice this morning. The 400 axis arrow at 400 grians, 85 grian thunderhead, blazer vanes blow through her so fast she didn't know she was hit. The arrow stuck in the ground about 6 to 7 inchs at 25 yards and she only went about 50 yards this morning. That the way I like to get them with fast kills. Thats one of the reasons I said I will never look back at the way it was before. I owe it to the deer and my sport to make fast clean kills.
