I finally go my hands on some Jim Shockey Gold powder - got a pound of ffg and a pound of fffg. Went to the APP website - they only show data for the ffg. And show load 100 gr. and 120 loads for 240 sabot bullets. Is this stuff like T7, where the upper limit is 120 grains; or is it more like Pyrodex RS? Can I load a 250 Shockwave to 2,000 fps in an Omega? It looks like it going to take maybe 135 grains of ffg to get there. Don't have a clue how much "faster" the fffg burns . . .
