I was given a hawmins 50 cal for x-mas It will not fire. I can pull the triger 35+ #. The set take up triger works but the set triger just goes click. no nrop to the nipple. any sugestions? It is a long time till ml season but i want it to work darn it. I love my inlaws but I should have gotten a tag with it with adisclaimer about some assembly required or repairs needed.(-:
