Has anybody ever gone this light? Got the little woman a S&W 642 and want some nice light loads for plinking. She's a bit recoil sensitive but I really just want to tame the beast that can be an Airweight. I know I could load 125gr or wadcutters but my local gun shop has 93gr lead for cowboy action. Thoughts on this bullet/powder combo?

I guess nobody has ever loaded a 38 with this load.

try W231 with 3.5 grs which gives 689 fps with a90gr lrn! Its the lowess chamber pressure in my reloading book.

According to Lee's Modern Reloading current version with a 90g Lead bullet and trailboss is 3.0 gr at 740fps to 5.0 gr at 904fps 8100 PSI OAL 1.325.
For the 125 gr with Trailboss it would be as follows:
3.0 gr at 753fps to 5.3 gr at 952fps 13400 PSI OAL 1.445
Hope that helps but both should be a very low recoil load with ever bullet you use.

I carried an Airweight for years as a backup. Best thing I ever did was to replace those tiny grips with Hogues. Making shooting the little gun with even service rounds bearable to borderline enjoyable.

joecil, if u can please look up the loads for trailboss with a 150 gr lswc for 38 sp ? My book doesent show it... thanks....

It doesn't show a 150 gr lswc but does show a 148gr Wad Cutter with trailboss.
2.0 gr 625 fps to 2.3 gr 675 fps 15700 PSI OAL 1.160
Oh and guys Lee is the only book I have that actually lists Trailboss powder. I've not seen it in my Lyman, Speer or Hornady books at all. Oh and all my books are the latest editions.
A rule of thumb is 70% of case capacity with no compression. That is listed in a PDF file by IMR as well as some load data listed there in a couple of PDF files.
Here is the data listed in the PDF for handgun loads:
