.40 s&w
I am looking for the cleanest burning powder for a .40sw load along with some data to make a 165 power factor. Any suggestions?

I use 4.9 gr. of WSF under a Berry's plated 200 gr. RS. I shoot a Para Ordnance 16-40. If you decide on Berry's plated bullets, see if they'll sell you double struck bullets. They will be offering them in every size soon, but some don't show up on their website.
