You need to get reloading manuals,

I am waiting on the toolhead / conversion and will be loading on a D650. The PMC Bronze 165 gr shoots very well out of my SC. I have not run any .40s over the chrono so not sure what velocity i am after but that load will be the first to get duplicated. I currently have some 155gr plated FP and 155gr LSWC. Not so sure if the LSWC will work well but I picked them up in a barter deal. My .45TAC doesn't like the SWC profile at all. Any load data and results would be great.
seriously. The more data you have at your finger tips, the easier reloading is. Two good manuals is a must IMO. The Speer #14 & Lyman #49 are the best for handgun reloaders IMO. The internet is a great source, but there is a lot of hearsay & unvetted info. Reloading manuals print tested data. Loading w/o them is shortcutting your way into a KB IMO.
Ok, w/ that out of the way, Unique & other med burners, like WSF, Universal, PowerPistol, HS6, all work very well in the 40 for midrange to full power loads. Unique & WSF are my fav choices for any bullet wt or type in my 40s. The Speer #14 shows 7.2gr-8gr for the 155grTMJ. W231 works fine for light loads to midrange
loads in the high pressure 40. Speer says 5.8gr-6.5gr. Keep in mind that the max pressure charge of W231 is producing the starting vel
