For light target loads I reload Mid-range wadcutter equivalants (146 grain Double end wadcutters over light charges of Bullseye). Extremely low recoil and quite accurate. My Mark III loves them.
For a bit more bark I load 158 grain SWC's over modest charges of hodgdon Clays.
I've been using 4.0 grains of Bullseye under Rainier Ballistics 125 gr. bullets (lightly crimped) with CCI small pistol primers. I use the same load in .38 and .357 cases. Very mild recoil in the heavy framed Troopers and Pythons.
That sounds like a good recipie to me too.
I really like the ranier bullets for light loads especially with Clays powder. I find a lot less soot and ash. Basically they shoot VERY clean in my revolvers.
