Karl,
I like to shoot my 357Mag lightweight J frames, as well as K frames, and others, but don't enjoy the beating that the J frames do to my hand/wrist/elbow. Below is the load that I have settled upon that works well for me, and my handguns:
Bullet= Xtreme 158gr PSWC (you could substitute a 158gr lead RN or SWC here)
Powder= 4.4gr Trail Boss powder( a fast powder with a high loft)
OAL= light roll crimp to the cannalure on the bullet
Primer= Federal SPP(some of my revolvers are "tuned" and these primers are the easiest to ignite)
These loads are easy on your brass, and a dream to re-size......plus fun to shoot !!
