I have owned both and shot game with both. Ruger pigeon holed themselves with hornady and there ammo and brass. And In my opinion the h and h has been and always will be the king of the 375 bore diameter. Is the ruger a better more modern case design absolutely but it does nothing in the field any better than the ol tavern wench. Now the 378 weatherby and 375 Rum that’s another ball of wax.
