Swiend,
this powder will work, however I will go with IMR4064, IMO better choice.
7.62x54R
Cart. Length = 3.040
Charge Max = 58grain (52,000psi, max you can go is 56,500psi, so still bit room to go up, however I would not recommend to pass this for safety reasons)
Bullet crimped
At 58 gr, it will fill the case up to 94%
This powder will not burn fully in 1890/35 barrel
Velocity with 150gr Speer SP #2217 should run around 3000fps
Good Luck
Peter
