The attraction to me was the fact that Pioneer is ascorbic acid based.  Got a good source for vitamin C powder, in case of a SHTF scenario, all I'd need is a nitrate source, and some time to experiment to get the ratio right.  The patent for the stuff is online, but isn't very specific.  Works great in my 50cal muzzleloader under a TC Shockwave 40 caliber, 200gr sabot.  Shot three into a 1.25" group at 100yds.   With 110gr pushing it, velocity, trajectory, and energy would be about the same as a 35 Remington.
