Idaho Shooter, I don't know just what the proper caliber and bullet weight would be for a real trophy Chupacabra, but when we were Mearns quail huntng, using #8s in my Rem. 1100, I ALWAYS had three 12 Ga. Breneke Rifled Slugs easily at hand.
When we were panning for gold, my old Marlin 336 .30-30 was always leaning close to my position, and my S&W 57 .41 Magnum with my stout handloads was ever on my hip. Even so, we kept one person as a lookout at all times, and yet, I felt somewhat undergunned!!
Those Chupacabras look mighty malevloent and fierce, and have teeth the size and color of over ripe bananas!
