My very favorite load of all of them is a 200 grain swc in the 45 ACP over 4.0 Red Dot. About 800 fps or so, not a barn burner, but it will put them in the same hole if I'm having a good day. Seat with a taper crimp, just a thumbnail of the bullet shoulder showing.

This load has fed and fired in every 45 I own.

Good luck!
