Has anyone read the Hopalong Cassidy books, by Clarence Mulford?
They were written back in the 1930s.
Part of the theme of these stories is how much better Hoppy and the Bar-20 cowboys can shoot than anyone else around them parts.
They shoot so well because they practice a whole lot more.
And they practice so much more because they reload all their own ammo.
The process they had to use is explained in the books and it was crude.
Melting lead around the campfire, pouring powder by kerosene lantern light in the bunkhouse, wrassling with knuckle busting reload tools.
Small wonder most folks back then didn't shoot enough to get very good.
Lock the doors, they're coming in the windows.
