I'D be tempted to look around for a Winchester M1894 clone, and have it re-chambered to .30-30 Ackley Improved. Still a light, fast-handling, durable carbine, with ballistic capabilities almost in the .308 range, but can still shoot .30-30 WCF if no .30-30 AI is available. I think the same could be done with a Marlin M336, whose stronger action design might enable a more complete exploitation of the .30-30 AI's ballistic potential.
I'm not in the market for one, but a Browning BLR, Savage M99, or Winchester M88 in .308 would be tough to beat as an "all-rounder".
