RE: Fun with my Chrony...
Finally got the 29" module in, and chronoed the same arrow set ups (350, 375, 475 and 500 grains) to see what I could pick up. I was curious as one of the options I have is to continue shooting off the string like I currently am but adjust my mongoose to it' s shortest position which will allow me to utilize my same comfortable anchor point. Here' s the deal-
grns 28" DL 29" DL
350- 295 fps/68ke 300 fps/70ke
375- 288 fps/69ke 293 fps/71ke
475- 256 fps/69ke 264 fps/73ke
500- 252 fps/70ke 258 fps/74ke
I was shocked to only pick up 5 fps at an inch longer draw. Since I like the way the gator jaw fits so well at 28" , I can' t see any reason to shoot at 29" if I continue to use a lighter arrow, which I plan to do this season. Going up will require me to either go back to the GT hunters I have, which isn' t happening, or buy new ACCs, which is expensive for gaining a tad over 1.5% in fps.
On the heavier arrows, performance jumped up 6-8 fps, or 2-3% gain. Probably not enough added trajectory advantage to again warrant purchase of new ACCs.
What this exercise seems to have taught me is I' m very happy and confident with my current set up. I' m no longer wondering if I' m missing something. I also will never again use rule of thumb guesstimates such as " an inch longer draw length will get you 10 more fps" etc, as there are two many variables involved.
