I just got my new limbs for my2005 bowtech allegiance put on yesterday. So today I decide to go out and practice, after 6 shots my upper limb cracks. Has anyone had this happen to them. The dealer couldn't believe it either. I am shooting Beman arrows 9.3 gpi29" longat 60lbs. My first set of limbs had a crack on the lower limb. Anysuggestions are welcome.
