Some can say that " my .243 will do this "... or.. " my .500 super duper wiz bang tank smasher can do that ",...but it all boils down to one cartridge and every single one of us, deep down inside knows, that the most versatile, useful, well rounded cartridge is the grand old 30.06 Springfield,...we all know it, but lots will not admit it. From 110gr to 220gr bullets, varmits to moose, it's a real killer, just as accurate as any other hunting round, cheap ammo found anywhere, manufactured in all rifle platforms, by all manufactures, reloading components are cheap and readily available, recoil is no more noticeable than the rest of the standard calibers,..so whats not to like,....30.06 is the answer.
