Gentlemen,
I'd have to say one of the baddest of the gunfighters would have been Charlie Askins! Now, of course he didn't live in the old west, but he lived in the new west and started his gun throwing profession back in the late 20s or early 30s. I'm not sure how much of what he said was gospel, but in his book, "Unrepentent Sinner," he highlights some very violent accounts of a very violent time, in which he's throwing lead and people are dying. If he told the truth...or even half the truth...he could have knotched his gun butt till there wasn't any wood left!
