From the QuickLoad specifications:

................................WW296.........H110
Heat of Explosion / Potential ..4300..........4110...... kJ/kg
Ratio of Specific Heats.........1.235.........1.2200
Burning Rate Factor, Ba.........0.6300........0.7941.... l/s
Progressivity Factor, a0........9.0970........5.2172
Progressive Burning Limit, z1...0.285.........0.275..... x 100%
Factor, b.......................2.2416........1.8392
Propellant Solid Density........1.620.........1.620..... g/cm³


If these come out of the same plant to the same specification, this is sloppy replication of effort, given that the density is the only matching element. Both powders are in the same class and tend to produce similar ballistics, but are not a true match. Adjust your loads accordingly.
