Sgt Preston here...

I'm also a big Win 231 fan...

I load 4.0 grain of Win 231...

I use Berry's 158 grain flat point swaged / copper plated bullets...

They seem to fly fine & print the target right where I expect them to...

I shoot them out of an S&W 686 x 4" SSR...

I have probably loaded & shot 5000 with this load...

Hope this is helpful..!
