I'd be more worried about it exploding being more than 10lbs over the limb capacity. No wonder it's loud.
No joke, just because the bow will crank past the 65 lb mark doesnt mean its ok to. A friend of mine had a Indian bow that was rated to 65 lbs he torque the limbs asfar as it would go and on the scale it showed 77lbs after firing it like that a few times the top limb exploded into several shards of fiber glass and sent the cam through the ceiling, My friend had a nice laceration across his right cheek my guess one of the cables whipped back and hit him.
