Drew, I don't have access to a scanner where I'm at right bow. Here's a cell phone pic of that DuPont's Brandywine Lab data cited by Askins. See the 12-gauge/3-1/2 dram/1-1/4 ounce loads of its Bulk smokeless I referred to earlier.

Thanks Frank and I can't reconcile those numbers with Coxe's pressure curves or the 1927 SuperX flyer; 1000 fps at 40 yards, with a breech pressure of 3 3/4 tons or about 11,480 psi by Burrard’s conversion.
Coxe was the Ballistic Engineer at Brandywine
