James,
I am pretty sure every French proof powder prior to the year 1900 was a semi smokeless powder. The first truly smokeless powder was powder T, which became the default proof powder in 1900. People could and did specify powder S or J after 1900. It took the proofhouse a few years to get proof with the new powder completely sorted, and powder S was a higher pressure proof at the turn of the century.
Powder T is used to this day. French proof is, by law, the highest in Europe.
I really dont know anything about Ideals. At least not anything that matters.
Best,
Ted
French proof dates well back beyond the "Invention" of smokeless powder. Obviously former proof was done with BLACK. Plese define Semi-Smokeless.

As I understand it semi- was a powder that was the same volume as black but was cleaner. An old Sears catalog I have refers to it as White powder. Anyone that has any extra Ideals they want to move let me know please, Mark

Kings semi-smokeless & Lesmoke were both true semi-smokeless powders in that they combined black & smokeless. All the Bulk powders I am aware of were straight smokeless. This includes such powders as Schultz, EC, Dupont Bulk & others. These should be simply classified as Bulk powders, not semi-smokeless.

Powder production, at that time, in France was a monopoly of the French government. Arms were proofed with black powder, until semi smokeless and true smokeless powder loads were developed. Powder J, including J1 and J2 and powder S, were in use beginning in 1896. Powders M, R, and S were in use in 1898, and powder T in 1900. Only powder T is a true smokeless powder, and an early problem was getting the new powders to actually develop the 12,000 psi minimum that was set by the Brussels convention.
If you are asking me to define the ratio of black to smokeless powder in early French produced powder and proof loads, I dont have that information. You appear to have a clear understanding of what semi smokeless powder is, however.
The early semi smokeless powders used at the proofhouse, prior to powder T, werent in use very long.
Ive never seen a French proofed barrel with 5 crossed palms, either. I know what four represent, triple proof with black powder, to 27,000psi. Try that with your sleever.
I have no idea what five crossed palms represent. But, I wouldnt worry about what I shot out of it either.
Best,
Ted
