Any other votes for the .300 as caliber of choice?



Trust me, you want what is called "Professionals Magnum":

"Grandpas Magnum"......

Key questions would be type of muzzle break it has and barrel twist rate. Ideally you want to stabilize heavier bullets otherwise there is no point of having hole larger than .30 caliber. I would leave guns like .338Mag and .375Mags to them young whippersnappers!
