These are the heaviest loads I have found in the loading books I have.
From the Lyman 45th Edition, and the Lyman Cast Bullet Handbook from @1973.

With a 150gr plain base, or a 158gr gas checked Cast bullet they start with
4 grains of Unique for velocities @690fps.

MAX is 8gr of Unique for velocities of 1280fps for the 150gr and 1250fps for the 158gr.
These are from a 5" S&W Mod 27.

They also show 15gr of 2400 [this would be the Old 2400] as MAX with similar velocities.

Hope this helps.
