In any of the shooting sports, with the possible exception of air guns, they're some who want the absolute biggest bang! So when it comes to cap & ball revolvers the Colt Walker replicas offer the biggest and most everything else you can get. The Colt Company itself admitted that prior to the arrival of the .357 Magnum its was the most powerful revolver they had ever made, bar none. So if the biggest bang floats your boat it is probably the answer. But it should be remembered it was intended to be carried by a horse, and not a human - certain fictional movies not withstanding. And it will certainly lower one's powder supply faster in big gulps. That said, the idea is to have fun, which is defined differently by different people. Unquestionably it has an interesting history, and it's quite probable if Sam Walker hadn't come along only a few historians would remember who Sam Colt was. No one was more aware of this then the inventor himself.
