Does a .338 win mag offer a whole lot over a .300 magnum shooting 200-220 grain bullets for game elk size and up?
It offers a slightly larger hole, which some people care about. I am one of them. Other than that it comes down to personal preference, both will be more than up to the task of what you have planned.
Me too.
But the size of the hole has a lot to do with the projectile chosen and velocity rather than caliber, within reason. A Superperformance 150 gr. SST through my '06 tends to leave a larger hole through caribou, than a 250 gr. Game King through my .338 on moose with similar shot placement and range. Different constructions, and over 500 fps difference in MV.
