The video "Masters of the Barebow, Volume III". Rod Jenkins is one of the main players and he's an accomplished hunter and tournament archer. Regardless if the target is fur or foam, the goal is to hit the spot. The target doesn't determine what's a good shot and what isn't, you do. Col. Jimmy Blackmon is a heck of a shot, hunter, and has made his mark in tournaments...he's trained under Rod. Few people on earth have hunted and taken as many different animals in as many different places and terrain as Denny Sturgis Jr., and he's talked about how much his accuracy improved after Rod worked with him. Consistency is the key. To be consistently accurate you must have a consistent shot. Good form is about making it easier to make the exact same shot every time.
