I've got a Savage 340 in .30-30 myself, and it's such a joy to shoot. There's something about the feel of those rifles that just can't be beat.
A while back, I was in the same boat looking for a specific caliber and stumbled upon a site called
BulkMunitions. It ended up being a great find because they had a solid selection and the prices were decent. Maybe give it a look for ammo once you find your rifle.
