The old Speer manual had 250-260gr data but not any of the newer powders today. Several gamers I know shoot 250-2555gr bullets @ sedate 650-675fps for just making power factor. I have tried such loads but do not find them much softer shooting, cost more though. I have loaded 250grLSWCH @ 800fps for my m625 with good results & ran some in my 1911 just because, all good.
