7x57 & 300H&H, Ray, may I call that nostalgia or purism?

I agree the 375HH could be overkilling (but when You are owning a 375HH what's the use of her out of Africa?) but the tiny 7x57 is sort of a disabled compared to the splendid all-terrains 270. I cannot squeeze out of my mind that the 7x57 is an extra asset on a (ancient) drilling.
Kind regards.
