Ultimate Predator Challenge: Who Will Win?

Derrick and Trouper face off in what we are calling the Ultimate Predator Challenge. What we did was take a batch of rifles and found the rifle that had the closest groupings and furthest groupings. Now, Derrick and Trouper have those rifles and do not know which is which. They will both try their hand at shooting at multiple targets and see if they can figure out which rifle is best in this real-life simultion.
