Calculate my fps w/o chrono
I have an 08 Diamond Black Ice and the birth cert states 298 fps with a 350 grain arrow at 70# and 29 inch dl.
My arrows should be in the neighborhood of 365 grains at 65# and a 28 inch dl.
How fast should it be shooting then? I'm going to get it through a chrono eventually but it would be nice to anticipate probably what it will be shooting.
Thanks
