OnTargt2 Shaft selector program
 

Does anyone else use this program?
I have it, and lately i have been trying to spine some arrows for a PSE Laser 2 finger bow (yea its old with round wheels and all) but it shoots great. 46" ATA 9 3/4" BH 64#
This program is telling me to use a Easton axis FMJ 300
To me this seemed a little stiff. What do ya'll think?

something doesnt' sound right at all. You sure you dno't have the sync button hit? It recommends with my 43" ATA 70#, 7.25" BH PSE with a 29" arrow a .37" spine.

What values are in the "Arrow point" section?

RE: OnTargt2 Shaft selector program
 

I have 100gr. point listed w/ a 16gr. insert. The sync. button is off i believe because it says sync not un sycn.
I have a 30.25"arrow plugged in.

Could it be that i don't know the AMO or IBO speed of this bow. I can't find any info on this bow due to it being so old.

RE: OnTargt2 Shaft selector program
 

What is the IBO speed that is being used? I suspect that it may be to high. Perhaps you could try and find the specs of a similar bow and use that IBO speed. Also, is there any way you can shoot a known arrow through a chrono and then punch those numbers in? That should give you an good, approx IBO speed to work with.

I am using 190fps, and 20% let off. for right now i may have to try to find a similar bow and use its speed. I am at college right now so i don't have any access right now to any of the equipment i need.
Does 190 sound high?

RE: OnTargt2 Shaft selector program
 

If you are using 190 I don't see how the program can be giving you a 300 spine. I am with bigcountry, something is not right.

i'm not sure the FMJ 340 shows up green in the list it gives you at the bottom right, but when i click on it the indicator on the top right of the screen shows that it is way week.[:@]

RE: OnTargt2 Shaft selector program
 

Haha i think i got it the sync wasn't hit so when i clicked on the arrows highlighted in green on the list it was telling me that a 340 was too weak and a 300 was just right. Now it is the way it should be with the 300 being too stiff and the 340 being just right! But it is still telling me the optimal spine of my setup is

RE: OnTargt2 Shaft selector program
 

The optimal spine is .3019!![&:]

RE: OnTargt2 Shaft selector program
 

I think you are doing something wrong , I put in for specs 64# 30% letoff, I believe this would be closer, 46 ATA brace height 9.75. I clicked off the release aid button because the way I took it you are shooting this bow with fingers. For the cams I put in there 2 cam soft. then the point weight and insert. Arrow length 30.5 , I wasnt sure what your draw length actually is so I put in there 30 inches . Anyway the 340's showed slightly heavy. Here is a snapshot of what OT2 showed.

Acher 2 that is sweet how you got that on here! the only thing i can see that is different than mine is the target box is clicked instead of the hunting box. i get the same thing when i click target but if you click the hunting box the 340 drops right doxn into the acceptable spine range.
