Lyman's Cast Bullet Handbook lists loads using a 10:1 alloy with gas checks and they publish velocities up to a little more than 2,000 fps at pressures just over 40K.

The 10:1 alloy is a little softer than the Missouri bullet is.

They do not list IMR 4895 or H4895 as a usable powder.

I would normally use IMR 4198 or RL 7.

I think what you have would be doable within limits. I think the 27.0 gr load using H4895 might be a good place to start and end. You could drop the charge weight a couple of grains and have a workable load to start and then check for problems.
