I guess I'm the only one, but I didn't get good results with the APP powder. I didn't try the JSG, but the APP was very inconsistent in my Omega. I normally get sub one inch groups at 50 yards using Pyrodex pellets and 295 grain Powerbelts. The Powerbelts were flying all over the paper, and the sound it made was just 'not right'. People who were there said that big pieces of burning powder were visible going downrange. I was using the pellets, which were all different sizes. I never tried the loose APP. Never did figure out why I got such poor resluts when everything I've read about the stuff was good. Oh well, I'll stick with Pyrodex and spend a few extra minutes cleaning.
