RE: Some Allegiance numbers to chew on

All I know is that the w.o.w. factor is certainly in the upper end of the spectrum

My Allegiance draw weight is 60.7 and has a 29 inch draw

WOW, so my 432 grain arrow is or I should say my bow is 86% efficient with the 432 grain arrow? Am I understanding this right?

I ran TAP and the efficiency numbers I came up with are:
1.278 for the 304 grain arrow @ 308
1.31 for the 432 grain arrow @ 265

Are we talking apples and apples here?

Jerry,
Just for fun I would predict a 500 grain arrow to go 249.5 ft/sec. with your setup.

I just shot a 300 grain arrow at 309.7 fps consistent. My BC says 312 at 60.7# and 300 grain arrow. So with a peep, kisser , loop and hush kit , that is not far off.

I will go make a 500 grain arrow and let you know

I must confess I don't know what TAP is but the numbers you quote look just like the S.E.P. numbers. 1.278 and 1.31 are pretty close to 1.29 wouldn't you say?

My program predicted exactly 309.7 using 70grains virtual. Right on the money. I think the math model we now have for your bow is pretty consistent with your measurements.

That's what the numbers indicate. A final check would be to do a force draw curve on the bow to measure the stored energy. That would be a good way to confirm it.
