Great info...thanks! My bow is a Reflex Growler. It' s a 50-60 lb variable draw weight, but as a result of limb length being an inexact science, it registers 63 lbs when it' s maxed out...which works for me. I' m shooting 115 grain muzzy 4-blade broadheads and my draw lenght is 28 inches. I have mid-grade Easton Carbon arrows...so my hasty estimate would be that I' m getting about 240 FPS....sound close??
