Thanks fellas.
If I can't reach about 1150-1200 fps using either W231 or Universal, I'll look around at some of these other suggestions. I'm not looking for top velocity, but I don't want just a 950-1000 fps load either. I want accuracy too, of course. I plan to shoot tomorrow morning. I have three additional Ed Brown magazines, too, and I want to make sure all five of my mags work so each one will get a little workout.
Very nice 1911. I agree with those who recommend slower propellants than you're using. The old standby 2400 should be a good bet along with AA#9.
The 10mm is a magnum pressure chambering and needs the slower propellants to reach it's potential without going over pressure.
