Most mfgs dry fire thier bows quite often before they are even shipped to dealers. this tests the duarbility of the lims, cams, strings, etc. Check the limbs and cams before attempting to shoot, i recomend taking the bow to a pro-shop to have this done.

I think I read on another post that bow tech dry fires all there bows to test the durability, I dont know for sure though.
