Originally posted by Jacko: I had a look though my 3Rivers catalog and he lists a number of 100 grain broadheads you could use like the Magnus 2 or the 100 gr Grizzly in combination with a 75 gr steel adapter . Have you considered more weight up front Extreme Forward of Centre is critical for best arrow performance Could I also refer you to Dr Ed Ashby's broadhead penatration study posted on this website and his post today - Penatration and Traditional broadheads . regards Jacko
