140 gr cast 40 S&W loads

[Bushrat]

My son in law bought 2000 cast boollits for his Glock 40 upon arrival they were 140 gr.
Having trouble finding light to moderate load data. Would like to use unique but not married to it. Any help?

I was able to find some 150 grain data, so you could use that as a starting point:

I shoot a 155 gr SWC using 4.4 gr of WW231 out of my G22 with an avg velo of 846 ft/sec

Use 150 gr. data from your reloading manual(s).

I had excellent results with Auto Comp using 180 gr cast in my Glock 22. Hodgdon Reloading lists an Auto Comp load for 140 gr but its for the Barnes solids. They have a lot of other loads for weights in between.

Lyman's Cast 4th ed. lists a Lee 401-145-SWC with Unique between 5.0 - 5.6 gr. (p.262). The manual also lists a glaring warning against Glocks in particular. I'm using a gen 4 with no problems if that helps.
