Load for 45colt Cimmaron

[wls749]

Hey There,

I'm looking for a load to use in my Cimmaron and a Smith&Wesson 25-13.  I will be using 255LSWC and one of the followling powders:   
2400, W231, HP38, Unique, or XMP5744.  The primers I have available are Winchester LP, CCI300, CCI350, and CCI550. I'd like to achieve at least 850fps velocity. I've found any where from 8-9g of Unique, 7.5-8g of w231, 8-9g of HP38 depending on the magazine writer or reloading manual.  I haven't found any suggestions using xmp5744 or 2400.

Also, does anyone here load Berry or Rainier plated 357 bullets in 357 cases?  Not looking for any barn burners.
Thanks for your help,
wls749

ps. If you have a load let me know all the specifics including COAL.
