One interesting thing about the .300 Savage is that it gives most of the velocity of the .308 with *much* less pressure. Internal ballistics can be really weird sometimes.
I'd thought of the .35 Remington as being a junky old levergun cartridge that should have been forgotten years ago. Runs at 35,000 PSI, uses a chunky pistol bullet, etc. Then I found out that both Izhmash and Molot made domestic and Euro market AK-47s in .35 Remington up until a couple of years ago. I kept trying to figure out why, of all the cartridges in the world, they would pick an ancient American cartridge like the .35 Remington. I finally figured it was because the rifles were being sold to people who were using them to hunt for meat, as opposed to trophies. No, a .35 Remington is a bad choice for bear or moose, but there's a lot of smaller game out there to be had. The .35 is accurate enough, kind to guns and brass, easy to reload, and won't turn small game into a dense fog when you shoot it. It makes good sense, in a roundabout Russian sort of way.
A cartridge that's pretty much forgotten in the USA and Europe is the 8x56R Mannlicher. However, it's one of the most common rifle cartridges in India and fairly popular in Pakistan. During the days of the Raj the British prohibited civilians from owning sporting arms chambered in military calibers like .303 British, so the arsenals chambered their civilian offerings in the similar 8x56R Mannlicher.
