A quick glance through my reloading manuals (that list the twist of the barrel used to develop the 7-08 load data therein)
Nosler 5th 1:9 (Wiseman custom)
Speer 13th 1:9.25 (Remington 700V)
Hornady 5th 1:9 (TC Encore)
Sierra 50th Anniversary ed. 1:9 (Remington 700)
My Ruger has a 1:9.5
The only definitive answer from Google I could get on a Thompson Center (makers of the OP's Optima) 7-08 was on a "Scout", and it had a 1:10.....
....so it appears that the Savage is (or was) an oddball......
As the .244 Remington proved, one of the surest ways to kill a new caliber is to offer it in a twist that won't stabilize heavy-for-caliber bullets.....
