380 auto / WST

[ryan45kim]

Has anyone used WST to load 380 auto? I’m going to start loading 380 and have a good bit of WST and WSF I’m thinking that the WST will give better results. I’m just looking to duplicate a standard 95 grain FMJ load.

Winchester has never published data using WST for 9mm and smaller cartridges for some reason. I figured since it was such a fast burning powder and they didn't like the idea of using it in cases with such a small volume and since they have data for W231 they really didn't need another fast burning powder for load data.

I use WST for about all my lead reloads so when I wanted to use it for my 9mm with lead bullets I basically extrapolated data and worked up a load. I wasn't trying to push anything just find a nice load.

I have done a little work with WST in .380acp. It hits max fairly quick. I maxed out at 3 grains WST under Berry's PFNHB 100grain. It reached an ave. of 751 fps. Out of a KT P3AT. I did run 3.4 grain and got 879 ave fps, but depending on the brass I was getting guppies. Guppies were in R-P brass, others seemed fine.

btw: I do use Solo 1000 in the .380 with good results.

Happy shooting

Thanks for the responses, if WST will not work what would be you’re powder of choice?

I've used Titegroup, though several are listed.
