RE: 375 RUM OR 375 H & H?
My only experience is with the 375 H&H.
The 375 RUM clearly trumpsboth the Rugerand the HHperformance wise; however, on the other hand:
It does NOT dominate the 375 H&H in the same fashion that:
- the 300 RUM dominates the 300WinMag or 300WSM, or
- the 338 RUM dominates the 338WinMag,
more, but not all THAT much more.
If I was wanting more power than the 375 H&H I wouldstep up to the 378 Weatherby. That said, the 375 H&H is a capable yet easy going thumperthat has a huge following world wide.
375 Ruger? For something brand new, I am thoroughly underwhelmed.... I'll stay with the 95 year old stuff.... Rifles like a 375 tend to travel far, far from home and the ammo isn't guaranteed to always come off the airline with the rifle, especially these days, thus commonality and universality become a virtue.
