This is word for word out of AA 2001 Reloaders Guide:
ZMP-5744 (AA5744) This short cut, extruded, double base rifle and pistol propellant is designed for use primarily in the Sharps Rifle Cartridges. It also works well in large capacity handgun cartridges of both conventional and IHMSA design. Shooters of cast bullets and reduced loads will find it useful in just about everything from 22 Hornet to the 50/140 Sharps.
NG* % 20.0%
Avg. Length .048
Avg. Grain Diameter. .033
Bulk Density ** .880 (Very low. ease of ignition and consistent velocity, regardless of powder position in the case.)
Comparative powders "Beyond Comparison"
* NG- Nitroglycerin (glyceryl trinitrate)
** glcc
It needs a heavy crimp or high SD of the bullets used.
Also, a high NG content reduces the effect of humidity and temperatures variances.
