Thanks GMMAT.
Yes, I have access to a bowshop. I shoot a BowTech Guardian with a 29" draw, set at 70#. Yesterday I had it chrono'd at 317 fps. I had the arrow weighed on a digital scale at 390 gr.
Then I wanted to know the KE of thatset upso I looked up a KE calculator. Using the one at this link: http://www.bowhuntinginfo.com/Kinetic%20Energy%20Calculator.htmkinetic energy was 87 ft. lbs. with that scenario.
Do you have access to a local bowhsop? They should have a chrono you can shoot through and a digital scale (to measure the weight of your arrows). In the absence of a digital scale.....you can look up the various components that make up your arrow, online, and come up with a guesstimate on total arrow weight.
That's all you need. Arrow weight (total) and arrow speed to figure KE.

RE: Ethical Arrow Weight
Not saying your not right either, but I had a similar setup out of my Guardian(before I switched to 60# limbs). If my memory serves me correctly, I believe I was getting about 290fps, with a 390g arrow, 29"@70#.

RE: Ethical Arrow Weight
Yeah, I thought it was fast too. I shot it three times through the chrono to make sure. First shot was 319, second 317, third 318. Based on the consistency of the readings, I went with it.

RE: Ethical Arrow Weight
Like I said.....(and I own a guardian, too
)....it sounds about 20fps toofast. That's one HELLUVA discrepancy if the Chrono is "off" that much (and again....I'm just saying what gives the appearance, to me, of being "off").

Yall got me nervous now. I'm gonnago to Bass Pro tonight (puke) and have them weigh the arrows and chrono the shotto see if there is a difference.

Crow, you have nothing to be nervous about!!!! Even if the chrono was off 30fps that would leave you just under 70#'s of KE,that up is still plenty to harvest any north american game!!!!!
