I'm a newbie when it comes to guns so this may be a bit dumb. I recently purchased a rifle which says both "Springfield 30.06" and "Savage Super Sporter," which confuses me as I thought those were two separate companies. It also has "Hi-Pressure Steel Proof Tested" stamped into the barrel. The serial number is 10769. What is this? Am I safe to fire modern ammunition from it?

Also, I'm trying to buy spare magazines, the one it came with is a four-round.


Any help would be greatly appreciated.
