I do not look at kinetic to judge my arrow I use momentum to get where I want. I try to get above .57 slug-ft/s. this number comes from years of testing by dr ashby.
I do not know if this is write or wrong. This is just a point I picked to getLast edited by enewman; 06-11-2013, 06:11 AM.

KE is the number that 99% of bowhunters use when talking about their bows. Momentum is actually the ability of teh arrow to penetrate a medium, hence the more momentum you have the better the arrow will penetrate.
Example: 410 grain arrow @ 314 fps with 88#'s KE and .54 momentum
560 grain arrow @ 270 fps with 89#'s KE and .67 momentum
Still had the KE, lost speed, but made the bow quieter by a long ways, more forgiving and accurate for me at longer distances and my pin gap did not spread out that much past 40 given a heavier arrow looses less speed downrange over a light arrow and when this arrow hits, it hits with a lot more force and punch than the 410 grain arrow.
