Cowboys TV Show

I was watching a show on the Outdoor Channel, Cowboys. It's about the Cowboy Single Action Shooters Assn and that kind of shooting. This show they were at a guys ranch in N. Dakota that raises buffalo. The show goes on to show a lot of different types of "buffalo guns" and highlight one that the host had made up for him. It was a mini Sharps rifle chambered in .454 Cassul. Then the host and the ranch owner are riding horses on a buffalo hunt. The hunt climaxes where there are 6 or seven buffaloes, the host slides off his horse in his frilley leather period clothing, sets up some shooting sticks and shoots a bison killing it in one shot. Gots no problem there, but what did strike me as kind of hokey was you could see 3 of the fences of the pen they were in, litterally the pen was maybe 100ft square. The great white hunter shot the bison at maybe 15-20 yards and the buffalo were standing and eating where a round bale of hay had been. The others didn'nt even flinch when the shot went off. To me a real hunt would be oh I don't know at least somewhere other than a feed lot and with something other than a pistol caliber at a realistic range of at least out of bow range. There are some truly free range hunts, like Sasakwa went on, that would have been better to showcase the guns and tactics used back in the day, that would not feed right into the anti-hunters arsonal.
