I just got my new Dwyer over the weekend. Its a 65 lb at 28 inch bow. I already have a lighter Dwyer 56 lb at 28 inches. I was trying to get the same cast out of each bow. - (so I could shoot which ever one I felt like with out having to adjust). Out of the 56# I am shooing a 505 grain 3555 GT. (Arrow speed at 172fps.) For the 65 I am shooting a 647 grain GT 5575.(Arrow speed at 168 fps). For the little bit I shot over the weekend the cast seems to be about identical for both bows. Based on the speeds and weights above does this sound about right? - Guess I need to shoot a bit more and see what happens.
