Q2 shooters ?
I'm shooting a 70lb Q2 at 62lbs 29in draw and only getting 230fps with 2213 476gr total wieght arrows. Is this common being turned down this low or should I be concerned if so what should I check?

bo539 I just left you another message on the other thread .If the draw that Mathews uses to get their IBO speed is using their 30" draw that would actually be 31" for the amo draw and that might explain the difference that I was coming up with.I would say that is what is happening.

tfox is right on the $ I was reading were they tested the sq2 the same way mathews test them & they were 5 fps. slower then mathews.But hey it's still the best bow you can buy so don't sweet it ..

That sounds about right. Your shooting a really heavy arrow with a shorter drawlenth. I shoot the q2 with a 30 draw 65 lbs and 420 grain arrow and it's at 265fps. A little slower than I thought it would be but you know when you can hit a soda can at 40yards doesn't matter to much how fast it is. lol..

RE: Q2 shooters ?
The reason it's "slow" is because you have the bow set-up for it's worst efficiency.
By turning down a 70 Lb peak bow to the low 60's you are putting the cam out of time drastically (And SL type cams are VERY sensitive to any timing changes), you are increasing the brace height, and not putting enough pre-load(or stress)in the limbs. All 3 factors combined add up to a poor performing bow.
By getting a pair of 60 Lb limbs (or "heavy" 60's, are available form Mathews if you want a few more pounds), you will get a quieter, faster bow that has a better feeling wall and nicer force draw curve.
My 28" cam Q2 at 76 Lbs ("heavy" 70 limbs) shoots a 435 grain Easton A/CC 3-60 arrow at 274 FPS w/ a fletcher tru-peep, Loop, and 2 Sims String Leeches. It will do 245 FPS w/ a 520 grain 2315.
