i gotta disagree there. I've done it, once on a bad shot too far forward.

Also shot a deer quartering too much and sent one at a sharp angle behind the shoulder and out through the hard "knuckle" of the hip.

100 grain Muzzy 4 blade and expedition hunter carbon arows..

it can happen.

PS-- both shots were less than 20 yards, on smallish deer, 100- 115 lbs
