No...never bent a furrel on a Muzzy....but never hit off shoulder with one either.
Once you peg the off shoulder deep, and the other shoulder comes back, the arrow, adapter post, furrel and bhead tip can be in jeopardy of damage....all the components of an arrow are not bomb proof. I've got a bent ribbtec and grizzly here at the house that are bent as well.
One good thing about pegging the off shoulder is even if you do damage your equipment, you always end up with meat.
Mark...haven't had time yet to get to C'ville....will call when you do....save me a couple.
