Destroyer 340 peak draw weight
 

I have a D340 that I cannot get to the 70lb peak draw weight. I have contacted bowtech to get the factory specs.

I have the cams timed equally between the timing dots and the ATA is dead on at 32 3/8 and the draw weight on my scale is only showing 65. I have added significant twists to each cable which decreases ata and increases poundage and tried removing twists from the string which I thinks should increase poundage but correct the over rotation from adding twists. And increase ata.

I can't get over 67lbs and it really throws off the ata and timing.

Any suggestions? I can't see removing or adding more than 2 or 3 twists.

The birth certificate said it had been tested to 71 lbs

Any help would be appreciated.

Thanks In advance

What's your draw length? I just did a search and came across Bowtech's manual for the Diamond Razor. Says they test the bow for speed rating using a 29 inch draw, they probably use a standard draw to generate their statistics for their bows. If you are shooting a shorter draw, you could be giving up a little energy over test conditions. (Just a thought)

My draw is 30" but I think I should still be able to get 70lbs

Well, that would pretty much shoot my theory. I doubt they test any longer than that, and you'd have to get shorter to lose energy. It was just a guess, good luck.

Is putting twists in the string how you adjust the draw weight? Or can you tighten or loosen the limb bolts to adjust weight?

In this case I have the limb bolts tightened all the way down. Adding or removing twists can increase or decrease the draw weight.

maybe you need a new string or your tension gauge is off...
