It’s very simple to pop a jaw bone out on a deer getting caped. Slide the bar down the outside of the both knocking tissue away. Reach back in with loppers and cut bone. Slide bar in back of mouth over the cut bone and it slide right out. Rocky Willamson thought me that way in Dallas county back in the early 90’s. We did it for clients all the time cause we figured once they left we’d never see the jawbone again
