We've had a .375 round that feeds perfectly in the 98 Mauser without and modifications for a long, long time--the .375 Whelen. It's an excellent round, especially in the improved version, capable of easily 2700 fps with 250 grain bullets. Let's call the 375 Ruger exactly what it is--pure and simple a marketing ploy to sell people something "new" that they don't really need. Don't misunderstand me; there is absolutely nothing wrong with marketing something new as this is what keeps our economy strong. Just don't try to BS me into the idea that this new cartridge is the end-all-be-all that I've been waiting my entire life for.
