Nope. No way to tune bow to arrow. With crossbows one tunes the arrow to the bow. Generally speaking arrows with 20% FOC (not kidding) will fly truer from crossbow than those with 10-12 % as used in vertical bow. My 'arrow of record': Gold Tip Lazer II with 100 gr brass insert & 2" Blazers. For my 2 bows at 280 and 315 fps I use a 100 gr head, giving me a 405 gr arrow. For my 350 fps bow I use 125 gr head. Slick Trick mags are my preferred BH's.
X2, although I've gotten good accuracy w/ field tips at less FOC. This is a real popular setup w/ a lot of the Excal crowd, once I tried these components, I flat quit fooling w/ others. I still have some customs [as above] I bought two yrs ago w/ wraps and 4" vanes I'm using for fall hunting as I have bear here and the customs weigh 446 gr.
I asked this question in another thread with no response and thought I would ask the question again. Are you guys really setting up your arrows with over 20% FOC balance? Is there a point that might be reached where the FOC is too much or are we better off using brass inserts and the heaviest broadheads we can find? I am an old verticle bowhunter myself and 12% is ideal for my arrows with 100 gr broadheads. Anyone care to respond?
