That guy is amazing. That guy's revolver skills are pretty much the pinnacle of what's capable with a revolver. I really don't think it's possible for anyone to improve on that.
Here's another insane video, though from a different shooter:
I don't know who the guy is or what he's using, but it's not a modern revolver and definitely some sort of old 6 shooter (colt SAA or something?).
That was pretty good. This guy can reload a magazine pretty fast. I'd like to see him during a competition. What kills me about Youtube is the stupid comments people post.
