Hi and thanks for indulging a Savage newbie... My recent birthday present from me to me is an older Savage 99. I'd been looking for one in .308 and found it unexpectedly just in time for BDay.

I think it is a 1956 99RS, but I am a total novice at Savage identification.

Serial is 910XXX and here is a close up of the cartouche (?) on the frame by the lever.

Any input appreciated!

(after dialing in the old Lyman 4X that was on the rifle, with 110 gr UltraMax ammo, it got 1" groups at 100 yards)
