Try Stu's Calculator V.2 online....it is a great Excel based program were
you can enter all of your variables an come up with the perfect setup to
fit your needs. It is only as good as the accuracy of input information
though so take the time to be exact. Also calculates FOC%, estimated FPS
and total grn weight...and it's free....down load the accompanied
instructions as well. Good luck & tight groups!
