My Alliant handbook only shows Rem, Win, and Fed hulls. The Fed being straight walled like Cheddite hulls I would think the same data would work seeing how all the loads are 7000 to 7600psi. They're using from 21.5 to 22.5 grains of GD, different wads and just Fed primers. All loads were at 1290fps. You probably go up .5 grs using the weaker primer if your barrel got a little dirty. Good luck.
