My stepson used up all his .450 Marlin ammo on the first day of PA deer season some years ago by shooting at deer running across a field. He missed them so we drove an hour that night to get him more ammo. A few years later he used up all his .257 Weatherby mag ammo on a SD pronghorn hunt. I couldn't find any of that. We scared up two rounds in his gear and the next day he shot a running antelope in the leg and missed it while it flopped around. He had to finish it with his belt knife. He doesn't hunt anymore.
