Dunning-Kruger - " a man has to know his limitations " Dirty Harry. I have killed elk with the 30-06 and 7mm mag. one with buddies 378 weatherby that was handier when we saw them. they all worked fine. my personal statistical sample is only 8. but I have helped and guided to 40 +. With that number I have experienced what works well. It is hard to get drawn in Arizona but we have some good sized ones.
