Forgot to mention, since you're brand-new here, Welcome to TreasureNet. : ) Also, I figured I should show you what a .59 Maynard complete cartridge looks like -- because it's rather different from most bullet-casings. It is actually made of two pieces of brass... a long cylinder, with a separate thin brass disc soldered onto the cylinder's base. The thin disc is much wider than the casing's cylindrical body, and there is a tiny pinhole in the disc's center. Quite often, the disc is found by itself, having come loose from the cylindrical portion of the casing. Most relic-diggers do not recognize that disc for what it actually is. So if you find one, don't throw it away.
And therefore, of course, you may also find the cylindrical portion of the casing, missing the disc. Don't throw that away either -- it is NOT a lipstick-tube. ;-)
