Around here pistol powder is as hard to find as 22lr. So one of the shops had quite a bit of Hodgdon Tightwad so I got a pound to test in my Gold Cup. 3.5gr behind a Saeco 200gr SWC grouped about the same as the w231 I had been using. I can find data for the 45acp and 9mm (haven't tried it in my 9mm yet). I was wondering if anyone had any info for a 38spcl loading. From my experience most powders run similar charges between the 9mm and the 38spcl. Pressure for same charge weight should be less in the 38 due to the extra case volume?? If I can't find any data I am considering working my own load up with a start charge in the 3gr range and go from there. I have never deviated from a load manual and am wondering if my logic is sound before I proceed.
