RE: What arrow mass will achieve tha maximum momentum?
I pulled an 82nd off the rack.The 29" module is installedand pulled 72.5 pounds. Add about 10-12 fps for another inch of draw length and you can get a pretty good idea what it will do.
It was shot through an Easton professional chronograph.
443 grain arrow...302 fps
502 grain arrow...283 fps
625 graub arrow... 256 fps
