Thanks O.L. for coming to my rescue. I recently learned of your tuning method in "Traditional Bowhunter" from "Tips from the Old Timer". I am in the process of using the bare shaft method of Black Widow(Beck) which I have used for years and to great success, and a final tune using your method. I can assure everyone who will listen, your broadheads and your field points will fly the same, in the same group, and are supposed too. If they don't, you owe it to yourself, the game you hunt, and the sport to get it right.....NUFF SAID!
