OT2 tuning thread

[MTSabo]

A while back there was a thread for running setups through the OT2 software. Id like to start it back up. If anyone wants theirs ran I'll hook you up here.

I need Bow make, draw length, draw weight, arrow make, insert weight, point weight, arrow length, fletching, and nock.

2014 CST 344, IBO with #2 cam, 27.5” draw. Arrow is a TKO RIP 250, 75gr Brass Insert, 25gr IW collar, 8gr X nock, 8gr wrap with 4 3.9gr AAE PM 2.0 vanes.

I used Victory’s calculator curious to see if I’m close.

Whats your point weight, arrow length and draw weight?

 

[nphunter]

Whats your arrow length and draw weight?

Sorry. 77lbs and 28”

 

[MTSabo]

Yes 100gr. Thanks, that’s almost exactly what victory came up with.

Pretty cool man! Could you check mine please?
Elite energy 35 73lb @ 30"
Victory rip 300 @ 29.25" w/75 gr hit insert 100 gr tip 3 fletch blazer with reflective bohning wrap and factory nock. Total weight is right at 480 gr. Shot this same arrow last year at 64 lb so I figure it'll be a little weak.

I guessed on the wrap weight to make it 480

This should be interesting. I was shooting GT Kinetic XT 200's but they wouldn't keep their specs worth a darn and now they all wobble and shoot poorly. I was going to order up some Axis Match Grade 260's but decided to try my old arrows first.........and they're shooting like a dream out to 80 yards......very consistent.

So.....PSE Freak, 32 1/2" draw, 75lbs, Trophy Ridge Crush 300's, 16gr HIT inserts, 125's, 30" carbon to carbon, 2" QS Speed Hunters (20gr), Bohning A-nocks.

 

[Tonto]

How about mine? I am afraid I may be a bit underspined...

Easton Hexx 330 spine
27.75" carbon to carbon
3 fletch blazers, 6gr each
9 gr nock
5 grain wrap
50 grain brass insert
125 gr heads

Prime alloy, ~335 IBO rating
29" draw
70 lbs

Thanks for being so generous!

Would you be willing to try it one more time with 100 gr heads and see if that gets me in the green?

Thanks!

youd have to go to 100 gr heads and the stock 9 gr inserts

Here is what 100 gr tip with 9gr 4 fletch looks like

Why is it showing the dynamic spine getting weaker with less weight up front on his setup? That's backwards.

Here's another one for you. This one actually BS tuned perfectly at 20 yards. Same setup for everything except 75gr HIT's and 200gr points. It's obviously going to be weak, but wondering what that dynamic spine shows now.

Im not sure why it does, right or wrong...
