No chart can take into account the angle of the shot. From taking nearly a thousand geese I can say with absolute certainty my least favorite shot is the classic Texas brain shot on geese. It is just so hard to get good penetration, to get a pellet into a vital area, for a kill which occurs quickly. A head on or side to shot is much more dependable in my experience. More geese die from wing injuries it seems, from the Texas brain shot, than from vitals being injured. And my last retriever came to hate retrieving cripple geese, with a broken wing. Seems the geese are a bit grumpy which make for a nasty retrieve. I hate when the dog gives me that shoot better look or fetch them yourself attitude.
