I'm about to get flamed.
I don't buy into any of the elmer keith hooplah.
If the shots he made were so often that he made them, why isn't anybody else doing it? Why is it all "accounts and writings?"
With peoples interest in the sport, and the amount of practice and technology that gets used in current time, I don't believe that he was that much better, if all, than today's professional shooters.
Every time a handgun capabilites discussion comes up, that same stupid name ends up in the thread. Quit telling other peoples stories. Honestly, if it is possible, SHOW ME. Don't tell me what somebody told you to read that some guy wrote about some guys buddy who hung out with the friend of the shooter who by the eighth person telling the story was amazing.
So yes, he shot a lot and was good, that is a general consensus, but really, shooting that much, you are gonna hit something far away if you keep trying.
When I was ten years old, I hit a flying seagull in the head with a rock from a slingshot at 75 yards. Am I the greatest wrist rocket pioneer ever now? Never did it again. A friend of mine shot a glass bottle at 300 yards with a 4" barrel .22 pistol - it took him about 90 shots.
So really, saying "this guy did it in a book" is not a justification for an argueable point. GO SHOOT, tell me what happens. You hit anything at 650 yards with a 44 mag, hell, you hit an elephant at 650 yards with a .44 mag, I'll be impressed.
