My string was cut last week. I had to replace it with a new Zebra twist setup. My limb bolts are tightened to its fullest position (70Ib,s)...The bow pulls right now at 65 Ib,s. What happened? The guy at the Pro shop told me it was because the string is new, shoot it some more and it should tighten up? Huh? If the string stretches how wll that increase my poundage? The bow is only 2 years old and prabaly doesnt have more than 500 arrows shot through it so I would hate to think that my limbs have already lost some ummmph

What gives here guys?
