I'm kinda in the same boat. Had a real nice accurate load with the 300 grain Speer Gold Dot all ready test on some unsuspecting critter . . . . until I tried the 200 gr. Shockwave. MyOmega shot it very well with 110 grains of JSG fffg. Chronograph is broken, so no idea of speed. Some other folks on this board (Cayugad?) have reportedgoodaccuracy using 110 grains of ffg T7 behind 200 grain Shockwaves, so I would suspect that going up to95 to 100 grains of fffg would be no problem.

The 40 caliber 180 grain Speer Gold Dot was the duty load for the law enforcement agency I recently retired from.Designedto perform perfectlyat about 950 fps. I don't think it would penetrate well at over 2,000 fps; although I would be surprised if it came completely apart.
