Here's a curve, possibly Hodgdon Clays from
http://www.arizonaammunition.net/
Note the powder is FFg. FFFg is similar to Curtis & Harvey No. 2 with a curve much like dense smokeless. From Sporting Guns and Gunpowders: Comprising a Selection from Reports of Experiments, and Other Articles Published in the "Field" Newspaper, Relative to Firearms and Explosives, Volumes 1-2, 1897
The Ballistite curve would be similar to modern fast powders like Red Dot
The choice of 32 grains of Ballistite is confusing, as 24 grains is the published load for a 3 Dram equivalent; 26 grains for 3 1/4 Dram.
Alfred Nobel's 'Ballistite' was introduced in 1887, patented in 1888, then ‘Sporting Ballistite’ (for shotgun shells) was patented in 1889, but not released to the trade by Nobel’s Explosive Co. until 1895. The published summary of the Trial states ‘Ballistite’ rather than ‘Sporting Ballistite’.
For the non-deep thinkin' MU grads amongst us,
pressures are pretty low after 18" no matter what powder is used
