The last load data I see for the 6mm Lee Navy is by Phil Sharpe, ca 1937.
Except for light loads with Unique and 2400 the only powder still available that he shows loads for is 4064.
The heavier of Sharpe's two loads with 4064 gets 2540 fps. He shows some a little faster but at higher pressure with powders of the day.

FWIW, the pressure given for the original 6mm Lee Navy is 43,000 psi, giving a MV of 2550 fps with a 112 grain bullet.
