If you're looking for any kind of accuracy (and I'm assuming you are), forget about the FMJ bullets altogether. Go with a hollowpoint or other hunting type bullet and you'll be far more satisfied with the results.
Definately need to pick up some new powder, too. The advice you've already been offered here is all good. H380, 4064 or a host of others will all do well. The powders you listed are all totally unsuited to this cartridge.
