Odd, maybe experimental, .50 cal shell

After doing some on line research I found that the shell in question is called a .60/.50. A war time experiment to develop a hyper velocity cartridge by necking down the .60 caliber shell and loading it with a .50 caliber bullet. The project failed by the way.

Here's a different .60 head stamp just for fun.

OK, maybe the .60 and the necked down 60/50 "failed" but the basic cartridge--necked up to the 20mm gave rise to the 20mm Vulcan (20 X 102) or originally the "M50-series" of 20mm which is still heavily used around the world today.

There is also a whole chapter devoted to the .60 caliber round in Volume 2 of "The History of Modern U.S. Military Small Arms Ammunition". An interesting read.

Two more out of my collection. Got these 35 years ago from a WW2 vet whos father was working at Frankford Arsenal on the .60 cal project. They had been sitting on the fireplace for decades and he had no idea that they were both cigarette lighters until I pointed it out. He got a good laugh out of it.
