First trad bow is in the mail, arrows will be tomorrow. So I'm chomping at the bit, and actually looking forward to tuning the system.
....then I got this hair-brained idea from remembering some people have mentioned using bullets to increase FOC and manipulate spine....
.224 bullet (I know the range goes from at 40gr-69gr..maybe even more) Put a wrap of teflon tape around it if needed and position by the nock. This lets you get overall weight up when you hit the wall of how much weight up front the spine will handle. You release the arrow and inertia keeps the bullet against the nock. Upon hitting the target the bullet "slides" to the tip taking your high FOC arrow into the EFOC range.
IF you were willing to mess with the hassle of "tapping" the bullet back to the nock each shot AND you could work out the kinks (like the bullet "rattling" in the shaft down the range) would you see the benefits of EFOC? The arrow MUST recover from paradox before reaching the target to see any benefits I'm sure.
I guess it's more of a physics question.
Of course, if you make a shot that normally would have come *close* to breaking the shaft it will definitely snap it with the extra 55gr in the nock.
What do you think?
