I used a .300 for everything for a few years when I couldn't afford a selection of firearms. The .300 with 150gr - 168gr bullets is generally going to ruin a lot of your meat. Almost all of these bullets were designed to expand properly with .308 and .30-06 velocities and the .300 just expands them too fast. Use a tougher (less expansive bullet) if you want something left to eat. I used 180gr bullets suitable for heavier game after the first couple bad experiences on deer. Found same 180gr Nosler partitions used for elk loads worked well.
