Having settled on the light WST loads for the 200 grain RNFP bullets I have in 45ACP and 44M, I calculated that I will have over 1000 grains of WST left after I'm done loading them. I don't plan to repurchase either those bullets or that powder after they are gone, so I decided to work up some light 9mm 125 grain Zero JHPC loads over WST, if only to save my other pistol powders for other cartridges.

There's scant published 9mm data for WST available (just a little bit, such as in the 4th edition Hornady loading manual), but people have played with it, and some people use it. I was planning on using the same COAL as Hornady uses with its HAP bullets, just so I'm certain the rounds will work in all my 9mm guns. That turns out to be shorter than what most people seem to be using, so I couldn't just steal somebody else's load and work up to that.

WST is about 14% bulkier than Bullseye. In 9mm the theory with WST is that you can fill the case, and as long as you don't compress the load, it should at least be safe, more or less. That worked out to about 4.0 grains at the 1.069" OAL that I was using with these bullets. So I loaded up some at 3.4 grains, 3.6, 3.8, and 4.0 grains yesterday and shot them today. The LC9s was up in the rotation, so that's what I shot them in. They were very light feeling. I didn't chrono them, but I'm guessing they weren't going very fast for 9mm. Primers were all rounded. Cases weren't sooty. There were no malfunctions. I need to look at them under magnification tonight to be sure, but my quick impression was that the primer strikes were showing variable depth in the 4.0 grain set. The powder does have a reputation for being spikey at the upper end in 9mm. I only loaded 1 round at 3.4 grains, but I loaded 7 at 3.6 grains, and I didn't get any malfunctions in my LC9s with any of those, so I'm thinking 3.6 grains will be fine. I guess I'll load up another 25 at 3.6 grains and run them to be sure. Then after I've run out of 200 grain bullets for my 44M and 45C loads, I'll just load 9mm until the WST is gone for good.
