Seeking 40 S&W / Lee 401-145 SWC Load data

[WheelgunConvert]

Apparently it’s an odd size (poor results?) on the light end of the spectrum. Hey, it was free to me. I have bullseye, 231, unique, BR-5, and titegroup on the shelf. It’s going to be used in a Beretta 96.

Thanks for your response,

My little Kahr likes it with 6.5 gr Power Pistol. I shoot it as it's easy to tell apart from the 175's as it gets sized .401 vs .402.

What would be wrong with using data for a 155 gr jacketed and being careful as you work up?

Exactly. None of those powders are going to give high performance, so just follow 155gr load data. If you want performance, use Longshot - THE 40sw powder.

I don’t know how I missed it but the Lyman cast book #4 has lots of information for that specific mould.

Thanks to all, now I have to hang my head in shame.

Please consider praying for the Ukrainian people.

231 @ 6.5 is stout, 6 is OK. 100 fps diff per GRT.
