Mid-range .357 data for Speer 200gr FMJ

[cherryriver]

I have some Speer 200gr .357 FMJs to use up and would like to make up a load that produces about 850-900fps in .357 Magnum cases.
I'd prefer to use Unique, since I stock it, although VV340 would be good, too. I could use a recommendation for a charge weight, since I can't seem to find any on the 'net.

You could use about 5-6 gr of Unique and be safe in a quality firearm. I used 200gr lead with that load and it shot fine. Chief aka Maxx Load
