I am trying to pick between a 6.5-300, 27 nosler, and a 28 nosler. Looking for a flat round that can take just about any game in North America. What are the advantages and disadvantages? Mostly will be white tail which is a bit over kill but also want a Elk gun, bear or whatever else I may get a chance to hunt. Currently I can shoot out to about 400 yards, I'm no ballistics expert so that is why I chose a flat high SD round. Hopefully will learn to reload in the coming weeks so I can make my own. Also, not wanting to go crazy on the rifle spend maybe $2,000 plus the optic. Any help is appreciated.
