A friend of mine gave me 1K of .40 cal. 155 gr. LSWC bullets and I am looking for a starting load. Most data I have found does not list this particular bullet. Powder on hand includes W-231, WSF, HS-6, and AutoComp. I would appreciate any suggestions.

Roadforeman Here is some data http://www.precisionbullets.com/PDF/maashl40sw.pdf This data while listed for 155 is all jacketed data may not help http://stevespages.com/400p_2_155.html Hope this is of some help. Their is a lack of good lead bullet data for 40 S&W,especially the light to mid weight bullets. Good Luck SJ 40

The new Lyman Cast Bullet Handbook has data for cast 155's in 40SW.

Oops! I lied. It's a 150 grain TC. It's a book worht owning though, lots of good data for cast bullets and enough info on casting to turn you into a caster.
