I came over a little rise, saw a deer leg on the ground. I thought, "Huh, somebody got one, but they wasted some meat on the leg." Walked a little further and saw the deer laying there. Stopped in my tracks, and thought, "Oh crap." I then saw the lion about 5-6 yards from the deer, about 15 yards from me. I reached for my pistol, then thought, "SH@#! I left my pack in the truck." I grabbed an arrow and began slowly backing out. I backed over the little rise out of sight, and did a sprint back to the truck. I decided that was enough hunting for one day.
One .357 pistol that easily reaches the qualifications is the Contender. It will push 2000fps with a 125gr bullet with about 1K ft lbs of energy at the muzzle if I remember right. That is a hand load.
