I think mule deer is the best writer in the business. After all my reading and getting a little wiser with age I have concluded anything I am likely to ever shoot at again will be deer and elk. 270 with 130 ballistic tips will handle any deer and my 06 with 180 gr partitions for elk. If I ever find I need to take a 500 yard shot at an elk, I'll probably just pass and be content with going to a restaurant that night. Paraphrasing a bit here but it's so true, beware the guy with a well worn single rifle. I have owned them all but find little real difference in killing power if your honest about your personal limits and ability given the overwhelming majority of hunters have very little time to actually learn to handle all the whiz bang marketing guns available.
