Joe, this is a .577 Turkish Snider cartridge (14.7x43R). These crude reloads, and many other variations, are attributed to Bulgaria, who captured thousands of these rifles during the Russo-Turkish War.

This one came out of Montenegro, but of course that means nothing, just mentioning. Thanks much Fede. Now I can move on to the next item.
