I use Lil'Gun, in my 458 SOCOM, and started playing with it in 44 Mag. pistol rounds. Clean consistent powder, that unleashes the capabilities of the 458 SOCOM.
I also load 28 ga. shotgun shells, but have not tried Lil'Gun in shotgun ammo. I have too many good powders for 28 ga. now, and am not looking for a new one there. Although my understanding is Lil'Gun would be a good candidate, if I were searching for a new 28 ga. magnum type powder.
Hodgdon load data does show some nice velocities for heavy bullets in the 357 Mag, for Lil'Gun. Given my experience with it in other cartridges, I would certainly give it a shot in the 357 Mag, if I had one.
