also keep in mind, you didn;t mention what weight your bow is set at, as SOME mechanical
s require a certain amount of LBS to use them so they work right
they sell one's for lower poundage bows as well, as higher(like for X bows)
hitting bone with any broad head is never a GOOD thing, IMO
heart ,. lungs, are where you want things and there rather soft tissue make up, so any GOOD SHARP broadhead will work, get off target some and anything can go bad!
