Equinox + carbon firebolt + boltcutter fps ?

[jcollins0001]

I am new to this site and sure this info is on here somewhere.

Any one run this combination through a chronograph and what where
the findings using the standard string that comes with the crossbow.

Equinox + carbon firebolt + boltcutter(150gr) = Fps ?

Thanks

Welcome Jeff glad to have you on here

Here's a little formula for you. Excals speeds are w/ FFF string and 350 gr arrow.

Your bow will get very close to that 350 fps w/ above. Now, subtract 10-12 fps for Excel string and one fps for every 5 gr of arrow weight over 350 gr.

350fps -12fps[string]=338fps-[418gr-350gr=68gr/5=16]= 321.
Strum chrony 318, diff of 3 fps.

Welcome to the forum. Had an Emax, came w/ FFF and 350 gr arrows, too harsh for my tastes, tamed it down some w/ your present string and 440 gr arrows, fwiw.
