Lots of good info here for you.
pay no heed to the pizzing matches that always seem to find their ways into these threads
The time tested and proven 6.5x55...30-30, 243 and the 7-08 are all great choices. Lots of factory ammo out there for all those calibers, and if you're so inclined to look for a good used one, you won't have to break the bank to find one.
