I recently bought a new bow. A Jennigs Strike Force, at 57#'s. I am shooting Beman ICS Venture 400's that are 28.75". I decided to use Muzzy 4 blade 100 grn broadheads. I did the math and my FOC is 11.74%. Is that a good place to be? Or should I switch to 85 Gr. heads for a better FOC? It has been pretty windy lately, so I'm not sure what the full accuracy potential for the 100 gr head is. Just wondering what your thoughts and comments are. Thanks
