Raimey:
The 1896 Winchester Catalog for Ammunition and Reloading reads as follows:
"The smokeless cartridge in point of excellence differs from the black powder cartridge only in smokelessness and cleanliness. Velocity and penetration remain the same. In the other class of cartridges may be numbered the .236 Navy, 25-35 Winchester, .30 U.S. Army, and .30 Winchester Smokeless. These are purly smokeless cartridges. The velocities obtained cannot be gotten with black powder, nor have we been successfully able to use lead or alloys without metal patches. These are cartridges belonging entirely to the smokeless powder class and cannot be used with black powder. Their excellence is in high velocity and consequent flat trajectory. "
In reading other data in the reloading section it states that Winchester at that time (1896) was loading with the following smokeless powders:
1. "E.C."
2. "Schultze"
3. "S.S."
4. "DuPont"
5. "Hazard"
I think the granular size and the case size dictated the load at first...not the "scoop"..obviously they experimented with fast and slow burning smokeless from the manufacturer's ...but even back then, they knew that whichever powder "most completely filled" the case, results were best...
Hope this helps....
