Good points. “Quigley Down Under” comes to mind.
Crossfire Trail is also good. The bad guy actor actually restores Winchesters as a hobby.
Some of the long shots in Quigley were at the limits, but a buffalo hunter at the siege of Adobe Walls made an 1800 yard shot with a similar rifle. Someone calculated the “bucket shot” is equivalent of hitting a shotglass at 65 yards with a pellet gun.
