My friend had good accuracy with the RCBS  200 FP bullet
over 680 powder.  I guess now 1680 in his 10" barrel
Wichita International Pistol.
A couple days ago 
"mdeland"(Mike DeLand), over on the Shiloh Forum has
mentioned he has Very good accuracy with the RCBS 35- 200FP
in his 357 Mag and in his 357 Maxi Martini Cadets.
You could ask him what his load is. 
I have been shooting the Lyman 358318 , 200grRN last gas check bullet in my own 357Mag Cadet rifle. It shoots very well, too. I am about to load up some of the RCBS 200FP for it soon. 
For full power loads, I think the list of powders you have
mentioned are the ones to give you the performance you want, including the heavier bullets. Check the loading manuals.
If you want to load to Lower velocities you might try 
slower rifle powders like maybe 4198. I would just load with Unique.

This guy seems to like Lil' Gun (and H110 if you go down to the additional loads.) (You need to Login or Register to view media files and links)

I don't have the data anymore but with 250 grain cast bullets in a 1 in 14 twist gun I had very good results with Reloader 7.

Try Enforcer / 4100

Having used 300MP exclusively since it first came out. AA4100 / Ramshot has been by far the better choice for small capacity cases. This based on the experiences of those in our group who have spent allot of time and effort working with them both. I might add I don't shoot any of the small capacity cases and possibly why the 300MP has worked out so well for me. It seems to like the cases with allot of air space.
