I been loading 38 spec with these they work great! Now the problem I have is switch to different cals 380 auto 9mm 40 s&w and 45 auto. I have 3 books lyman 47th and lyman pistol and revolver. Also the one that dillon sells for each caliber. In these cant find info to load these in any of them. Rainier says use lead loading recipes on the website. But the books have no weight matches for 40 S&W rob
