Well, the .300 Savage is ballistically superior, being closer to a .308 than to a .30/30, and you have the advantage of being able to load pointy bullets in a 99. The question is, can you find one? There seems to be many more 94s and 336s for sale than 99s.
If you find a 99 chambered in 250 Savage don't turn your nose up at it either, while it doesn't really meet my definition of a general purpose cartridge, the 250's illustrious history doesn't have much respect for what I think. The .303 Savage is more like a .30/30, but what the .30/30 does with a 170 the .303 does with a 180. Does that matter? Probably not.
If in the end you do choose a traditional .30/30 lever gun, you can load it with pointy bullets if you're so inclined, provided that you use it as a 2 shooter, one round in the chamber and one in the magazine. Each time you cycle the action after firing the round in the chamber, you can add another to the magazine. Something like a 125 Sierra can sneak up close to 2600 fps which produces a reasonably flat trajectory, about a foot low at 300 with a 200 yard zero.
