My experience has been with 124gr and 147gr 9's.
Titegroup and BE are both fairly hot powders. Clays in 124's can work "OK", but is erratic. (Totally a no-go for 147s...)
I'm going to stay the hell away from coated and titegroup - i don't give a shit if it is Bayou, Blue Bullets, SNS, etc... TG is just too hot and I hate cleaning things...
I've had good luck with HP-38 (aka Win231) and 147's. Soft, accurate, non-temp sensitive, meters god enough for USPSA/IPSC shooting. I'm liking my loading of 3.5gr and loaded to 1.125"
The 147 sized at .357" are here, under the 38/.357 bullets:

(it is the same 147 FP as for the 9's, just sized to .357")
My loading process:
I have enough bell to keep things from shaving.
I crimp to .375"-ish ... No issues with flaking/etc... (Lee Factory Crimp and "size" die - I love this thing)
Seems ok... There's a bit of smoke, but I can live with it. You'll see a little bit of leading at the crown, but not much.
It is fine to shoot .357" through a glock, mp, etc...
Good luck, man. Lemme know how it goes - I'll be checking back here.
