Im not sure what all of that node business meant. But my standard Tikka 1:8 (22" barrel) pushes 77 Sierra TMK @ 2930 fps using 2206H. And my Savage Lightweight with 20" barrel 69 grn Sierra TMK and 69 grn Targex @ 3K using 2206H too. No pressure signs in either load. Norma and Gecco brass. I find brass brands make a load difference in the .223.
