Suppose you were given an opportunity (and the means) to bring to fruition the wildcat handgun or rifle cartridge of your dreams. What would the parent case be (if not an original design)? Describe the case. Here are some things to consider: is it for a short-action or long-action rifle; belted or non-belted; rimmed or rimless; a shallow or steep shoulder angle; and minimal or significant taper. Consider how well it'll cycle, too. What caliber? What velocity would you hope to achieve, and what would be its purpose? Does it offer any real advantage over existing cartridges? Lastly, what would you name it (please keep it clean)? Here’s your chance to create your own cartridge and present it to like-minded friends. Be creative and have fun.
