In my 300WM I use both RL26 and 2217 but with the 200 gr ELDX both loads achieve similar velocity. 2217 at 77.5 grs gives an average of 2834.1 fps and RL 26 at 74 grs gives 2820.7 fps. 22 inch barrel.
So I guess your case using 212 gr bullets you should be able to get close to RL 26 velocity using 2217.
