As you may have guessed from the previous posts, fast powders and heavy bullets are a bad combination in the 40s&w. One other thing to watch is your OAL, keep it as long as possible while still feeding in your gun (I load all my 40s&w to 1.145"). Take a look at:

If you want to use those 180gr hard cast, try 4.3-4.8 grains of Universal for about 900-950 fps. Don't try for screamers, just get it to cycle reliably.
