Bowtech blunder?

[in da woods]

At the unofficial GTG, 3 of us we're shooting 3 different Bowtech bows. Guardian, Ally, &Trib. Ea bow was rated as a 70# bow. We used a scale to check our poundage. all were @ 62-63#. All of us cranked them down till they stopped, to see if we could increase our fps readings. We scaled them again, & all 3 were @ 64-65#. I scaled mine last month & had the same reading as this portable scale.
My question is; is it possible that the bows were stickered wrong, & those limbs R actually 60# limbs? I've heard that bows can go over their ratings by a few #'s.
A friend of mine said it could be string stretch. Just seems kinda funny that all 3 bows would have that problem.
What R your thoughts?

String and cable stretch can certainly reduce the poundage of the bow.

The fact that all of the bows are bottoming out at about 65# is not terribly surprising. Many bows direct from the factory don't make full rated poundage due to some initial string and cable stretch. The cables need to be twisted up a bit to get the poundage back in spec.

I have yet to see too many shop scales agree, nevermind everyones personal ones. I bet ya its the scale.

I'd bet it was the scale.

check yoru scale.....buy some 25 or 50lb weights and lift.....my personcal scale is dead on...


Ibet its the cable stretch....I think new strings can exceed max #, but after a while max will be less.

thanks much everyone, I'm going to take my bow to the shop & put some more twists in it. See how that goes.

I agree indawoods that that scale was probably off. Bloodcreeks Guardian was throwing arrows way to fast to be at only 60 lbs.

Well I went to my archery shop, & had him weigh it. It pulled 67.8 # on a digital scale. the shop put a couple of twists in & got it up to 69.9#. So I'd say that the scale we used @ the GTG may have been off. Acutally I like the 70# setting. The arrows are flying much flatter at 40-50 yds. BCrik, I'm getting ready 4 U next yr!

Definetly seemed like it was the scale when everyones bows came up the same. I wish that I would have pulled my bow when we were there. I know that mine is at 68.9. Would have been interested to see what that scale would have shown.
