I (and others) have only tried 1:10 twists and have been completely satisfied. From a 20 inch barrel 85 gn Nosler BT should be able to be pushed to 2850-2900.
Step up to a 24 inch barrel and you can get about 2900-3000 fps. This is really close to 250-3000 Savage. The Speer 87 gn HotCor has a little more optimum form factor.
I will look into the possibility of making barrels that will fit a Savage action.
