I went with my Son on his first elk hunt in Arizona and he was successful with this spike. We hunted for 5 days covering many miles on foot ( I'm still recovering) and only saw cows until he spotted this guy about 200 yards away. He shot him in the front shoulder with his 7mm RM and factory Federal 175 gr TBBC. Complete pass through and the bull only when a short distance. We had a great time, as it is always enjoyable to hunt with your child.
