SR 4759 in 45-70

[jgraham1]

Made a mistake on my last post, so here it goes again.

Does anyone have Speer jacketed bullet loading data for 350 and 400 grain bullets using SR4759. It is used for cast bullets, but what about jacketed ones?

Speer #13 shows its use with 400 grain bullet #2479 as a reduced load powder for modern lever-action strength rifles.
26.0 Start = 1,184 FPS.
30.0 MAX = 1,359 FPS.

Other then that?
It is too fast burning for normal pressure jacketed bullet loads with either bullet weight.
