This one time at band camp....!
Do your homework-know your bow-have confidence shooting it. Keep it close, keep it personal, keep it tight, hit em under the spine and through the ribs. Do this and any broadhead shot from a well tuned bow with sufficient KE will get the job done.
And for the record, my mechs suit me just fine. I could not have killed those animals taken with my bow any better!
