I have used both Blue Dot & H110 quite a bit... i like the way 110 flows from a measure, and drops more consistently than flake powders like blue dot.
I have also had pretty good luck with Accurate #9...in the contender, i seem to have better luck with 110/AA9, and in my 8" Smith it seems to prefer Blue dot.
As for bullets, i usually shoot the Sierra 170 JHC when hunting, it seems to shoot well in all my .357's. The contenders like the hornady 180 XTP, as do my contenders in .357 Maximum & .357 Bain & Davis. The Smith does not like the 180 XTP at all.
I will check load data this evening to see what powder charge weight i am using in the contenders.
Redhawk, i would imagine Lil Gun with its slower burn rate should make a pretty good fireball in low light doesnt it? i have never tried it in a .357 but think i will, i had some signs of high-pressure spikes using it in small cases like the .256 Win Mag & the .221 fireball so i sort of set it aside for a while...should be dandy in the .357 for heavier bullets/longer barrels..
