Probably have to go to a 50-60 lb. pull due to shoulder pain. Looking for some feedback from guys/gals shooting in this draw weight range.
Like to know arrow speed, draw weight, and arrow weight so I can run the numbers on a kinetic energy calculator?
Are you getting complete pass throughs? At what distances?
Type of broadhead and arrows?
Thanks in advance, greatly appreciated.
I shoot with a 50 pound mathews, running a 2315 and a 100 grain broadhead. Arrowspeed is around 200 fps, and passthroughs are pretty much guaranteed.
About KE . . . KE is pretty much a constant, it will change very little. In physics, the KE is supposed to be the same, no matter what arrow you use at any weight, if shot from the same bow. if your bow produces a KE of 40 with a 300 grain arrow traveling at 250fps. . . your bow "physics" wise, will product a KE of 40 with a 600 grain arrow traveling at 170 fps. (Using arrow weights and velocities only to demonstrate, not to be accurate). But, because of variables (like resistance, limb vibration, and other factors) your KE will change ever so slightly. . but it will STILL be very close to the same.
What you need to be concerned about, is Momentum. MO is the forward motion in which the arrow uses to penetrate. A higher MO will penetrate better than a lower MO. And MO will change drastically with arrow weight. There is a HUGE reason why BIG game hunters in Africa and such places use HEAVY arrows. It is called high MO. . which means much better penetration.
