Need a load for .40 S&W ... I just recently got into reloading. I know that .40 is not the best caliber to start with but I carry a XD-40. I am using Ranier 180gr. bullets. I noticed a lot of people use W231 but have read this is a fast burning powder. Any suggestions?
Many will recommend Unique or slower burning powders for 40S&W high-to-near max "full-power loads" and I would agree as I used Universal/HS-6/WSF/AutoComp for full-power loads. However, if you are looking to load lighter target loads, most slower burning powders won't produce optimal powder burn and resulting accuracy unless you are using high-to-max load data.

231/hp-38 works fine for my XD40. Start about 4.5 and work up.
For me, I would tend to use 4.5 gr as high range limit for 180 gr plated/lead bullets. Here's why.
With Rainier 180 gr plated bullet and relatively fast burning W231/HP-38, I found W231/HP-38 more suitable than slower burning powders to produce very accurate target loads using mid-to-high range load data that burn fairly clean too. I have pushed Rainier plated bullets hard using jacketed load data and found my accuracy deteriorate. With 180 gr TCFP Rainier bullet, I got better accuracy using
lead load data or start-to-mid range jacketed load data. YMMV

I introduce new shooters to 40S&W using 180 gr Berry's/Rainier/X-Treme TCFP plated bullets loaded with 3.8-4.3 gr of W231/HP-38 at 1.125" OAL. Produces lighter than full-power 9mm recoil yet very accurate loads and I work them up to 4.5 gr.
Current published Hodgdon jacketed load data -

180 gr Hornady XTP W231/HP-38 OAL 1.125" Start 4.1 gr (797 fps) 23,800 PSI - Max 5.0 gr (947 fps) 32,900 PSI
Here's
1999 Winchester load data for the lighter 170 gr lead bullet ... my take is that max powder charge for the heavier 180 gr lead bullet should be lower.
This is what Rainier Ballistics recommends for their plated bullets -
http://www.rainierballistics.com/loaddata.php
Rainier Ballistics, recommend using lead bullet load data when loading our bullets. There is no need for adjustment when using lead bullet load data. Our bullets are jacketed using an electroplating process and are softer than traditionally jacketed bullets; hence the recommendation to use lead bullet load data.
I usually don't recommend max load data to be used for higher pressure 40S&W with mixed range brass and unknown reload history/condition of brass as cases that have been reloaded several times with hot powder charges and "fixed" with undersize dies (U-dies or FCD/G-Rx) and brightly polished will often look "OK" like any other polished case.
In addition, if you are fairly new to reloading, depending on the powder you use (like Titegroup) with narrow start/max charge range, you could be over max charge and not know it if your scale is off by a few tenths of a grain (Some lower priced digital scales are off by .2+ gr and I highly recommend the use of
check weights). Yes, the smallest check weight only goes down to .5 gr.
Lee Precision Safety Scale pdf suggests the use of a small cut piece of paper to approximate .1 gr and my Ohaus 10-10/RCBS 5-0-5 beam scales will register that small piece of paper but many digital scales won't register .1 gr. Go ahead and try it on your scale. If your scale won't register .1 gr weight, now you may have a scale accurate to .2 gr.
