Before we get started, I am not talking about the 50BMG. I am talking about 50 caliber or 510 caliber hunting cartridges that fit actions like the Remington 700 and the CZ 550. Example: 510 Battleship, based on 416 Rigby cut off at shoulder. 50 WSM, WSM case cut off at shoulder. 500 Belted Magnum, BIG Weatherby 460 case cut off to 2.5 inches. I like big bore 500-510 caliber hunting cartridges so show off what you got.
