You need to take a look at Spencer Hoglund aka "Lead Dispenser" on youtube if you're interested in the "cowboy shoot".

Consider how much has gone on in the time that it has taken while you are watching the footage.

To appreciate what the top notch cowboy shooters can do with a lever action rifle (10 shots), two single action pistols (5 shots each) and a side by side shotgun (usually 4 shots +, no ejectors) you should give it a go.

Very addictive. Best thing I've shot since IPSC.
