Someone makes a black powder machine gun? Is it a muzzleloader? That I GOTTA see, if only to see a human move that fast!
Some years ago I read that the first cartridges fired in the prototype Browning .50-caliber machine gun were assembled with black powder. The story goes that the cartridge, first made by Winchester, was something of an unknown when it came to using smokeless powder in it.
John Browning told Winchester, "You make the cartidges and I'll make the gun, and we'll do some shooting." (Source: John M. Browning: American Gunmaker by John Browning and Curt Gentry, copyright 1964).
I recall reading that the machine gun functioned fine with black powder, a testament to its excellent design and reliability.
Now, I read the above years ago. It may be true. It may be an utter fabrication. I checked the above cited book and found no mention of .50 BMG cartridges with black powder.
It's probably deep within my collection of 900-plus American Rifleman magazines, an unbroken set dating from this month's issue back to 1929. Or in my incomplete set of Handloader and Rifle magazines.
When I meet my maker I'll ask Him, Her, It or Them if it's true. On second thought, I'll just ask John Browning. It's a short question, and I should be in Paradise long enough to get his answer before they tell me I'm trespassing and need to move along to someplace less
comfortable.
