Fifty Caliber Kill

John Ryker was no ordinary gunfighter. He was the best. Ace gunsmith, deadly bounty hunter and ice-cool killer all in one, his lethal gun-skill made him the most feared death-dealer in the violent West.
When a rich Californian businessman offered Ryker big money for a few weeks’ work, chances were he was going to have to earn it the hard way. The only way he knew. Which meant that lead was going to fly and corpses pile up. And Ryker’s most powerful rifle, the fifty-caliber Sharps—which could kill with accuracy from a mile’s distance—was going to see a lot of action.
