I agree, that the 375 Ruger is an excellent cartridge. I also think the 416 Ruger is an excellent one.
I have both, no regrets, and thoroughly enjoy using both.
Don't agree... the .375 Ruger is an excellent cartridge of modern design principles. I have a Ruger M77 African rifle in .375 Ruger and a M77 Mark II Stainless rifle in .358/375 Ruger... I carry the latter a lot while guiding, loaded with 225 Accubond, it is a flat shooting, heavy hitter.
