Bill, I was using a trusty old Bear Green Stripe takedown that is 50@28. (I draw 29") Gold Tip 55/75 with a 100 gain brass insert pushing one of the new Grizzly Instinct 3 blades. The bear was laying down at the shot and I think the arrow stopped where it did when it hit dirt on the way out.
I found the back part of the arrow where it snapped off about 30 yards into his death run but I searched and searched and never did locate the broadhead end. All I can figure is that it got flung far into the brush when it snapped.
