I'll stick with shooting over my LEFT shoulder with a mirror thank you. although one of these days I'm going to try splitting a playing card. I understand that splitting the bullet to hit 2 targets is best done with Black powder arms.
I've actually done that with a 45 acp at 7 yards several times (not lately). Next time I go to the range I'll try it again and try to get video or good pics.
I also cut a string that was stretched between two fence posts with a .223 (using, of all rifles, a Ruger Mini-14....imagine that).
That's about it for my extreme marksmanship skills.
I did hit a penny that I threw into the air at hunting camp once (with plenty of witnesses) with my old Buckmark .22........
but that was just blind damn luck. Did it on the first try and then put the gun up before they could ask me to do it again. I know a luck shot when I see it.
I want to try the trick Bill Oglesby did by trying to hit two different targets with a SA revolver in each hand at a wide angle apart.
