Had a Savage 840 for awhile, one of the newer versions of the 340 made, it was drilled and tapped on the side of the reciever. Very accurate with the Hornady Leverevolution ammo. Bought it used and one of the first things I did was replace the ejector and band type extractor. Also polished chamber because it had some extraction issues. Also need to be careful with magazines as they have a couple springs that hook into the magazine when it is inserted and the springs can get out of whack. A lot of fun to shoot when they're working.
Look for a very lightly used one, they were a budget rifle and not made to take the number of rounds a Savage 110 will. The other option would be to find a Remington 788 in 30-30, probably pretty tough to find, but a very accurate rifle as well.
