Personally, I used to use that bullet for heavy 38 Special loads, but there are well known problems (and solutions) for when used in .357 Magnum ammo. So, now I stick with 158/160 grain bullets in both cases and am happy.

The data I have here doesn't suggest using the Keith 173gr swc in 357 cases due to the long nose of the bullet protruding in the cylinder.
The only decent 38 special recipe I have is:
5.5gr.-6.0gr Longshot
173gr. Cast SWC
COL 1.522"
Est. 914-995fps
