I have lots of .38 Cal molds, everything seems to work in .357Mag, I do favor bullets from 140grs to 180grs.
I can't seem to really pick a Favorite. Maybe the Lyman #358156 (158gr) over max charge of 2400, or the Saeco #354 (180gr) over max 2400. Both Gas Check designs.
For a heavy target load, I like the Lyman #358429 over A stout charge of Unique. I also use the same bullet in .38-44 loads.
For light plinking/target load I like the Lyman #358477 over Bullseye. Or Maybe the Lee #358-158-RF, I loaded it for My Kids Cowboy Guns in light .38Spl loads and heavier loads for unspecified use in CALIFORNIA.
And finally the old "Original". 357Mag #358446, never really used it. If I wanted a hot load I went with the #358156GC. Just following in My Dad's Footsteps.
Of course N.O.E. ,Accurate and Arsenal make GREAT Molds. Many more good choices.
RCBS Too.
Do you want a clean hole in paper or a hard-hitting FP to put down an animal ?
Sorry, but I can't give you a single solid choice.
I can't decide myself, always had too many choices.
And for just plain plinking, the Lyman #358311 Round Nose. It just looks old fashioned and the rounds just drop into the chambers so smoothly.
Sorry
