Well here's my testimony. I won a pack of 180 grain heads in the mid '80s at a shoot, no longer made. Then with all the talk over heavy up-front weight, I decided to try them out. 2117 alum. arrows, I have a practice broadhead that I've tried to destroy. Stumps, rocks even shot a gopher at my friends house and richocet off the foundation, I can't say more! Use a ceramic stick to keep the blades razor sharp. Oh, and did I mention the big doe I shot with one out of a Black Locust selfbow 55lbs. Now does anyone have anymore 180 grain blades?
