MP 147gr HP.... Unique charge?

[emt1581]

I am using MP Mold's 147gr HP cast bullet. I'll be powder coating them. I have a bunch of Unique I'd like to use. From reading around, it looks like somewhere between 3.8gr and 4.3gr is what people use. Has anyone had experience using these bullets with Unique? How much powder did you use to keep them subsonic?

I'm using a CGS Mod 9 can if that matters.

Thanks!

I don't know how long the barrel is on your gun, but I would have a pretty hard time driving mine supersonic. 3.8 Grains Unique only gives ~940 fps from my Sig 225 with a 3.9" BBL. I use Power Pistol more commonly.
