Agree completely Bob.
I witnessed the aforementioned Orthopedic Surgeon kill a big (and tough!) Sage Grouse stone dead at 50 yds near Pinedale, Wyoming. I cleaned the bird and found NO pellets - clearly killed with a single golden BB to the head, or in light of it's apparent age, a heart attack from the excitement. Unfortunately, the fella then came to believe he could kill ANY bird at 50 yds. He is a VERY good field shot, but not that good frown

I have been surprised at the number of c. 1900 12g doubles found to be choked about .005 right and .040 left.
