How much speed do you loose when you increase arrow weight? 20gr. increase=?? speed loss. I'm asking because I went from a 371gr. arrow to a 406gr. for hunting. The shop I was at did not have a choro. With the 371gr.arrow I was at 310fps.How much speed do you think that I lost? The nearest chrono is almost an hour drive one way. Any educated guestamations out there.
THANKS,
MAtt

Figure about 3fps every 10 grains.
