Malamute:
We had a Savage 99 in 300 Savage in my family. We reloaded for it and as I recall, the round was very accurate and easy to load for. While I have often thought about finding a 99 in 308, realistically I think the 300 Savage would do everything you need without too much difficulty. We loaded the gun down with Speer 130 hollow points and it was a great varmint round. We killed a number of white tails with it without any drama. The gun was easy to carry, had a decent cartridge capacity, was easy to scope and accurate. If you could lay hands upon a gently used Savage 99 in 300 Savage, I think you would be well served and probably have a true all-around rifle. Even as a grizzly gun, I think you could load either 180 grain rounds or go with a 150 grain Barnes X bullet and do just fine. Since you are a skilled reloader, I don't think the lack of widespread 300 Savage ammo would be too big of a deal. Buy 200 cases, treat them carefully and you'd be set for the rest of your days.
Let me know what other questions you have about them and I'll be happy to respond.
