Accurate #7 is also great for the 180s in a 10mm. I don't think I'd use any of the powders you listed, they are pretty fast for a 10mm. Even #7 is pretty fast, but recoil isn't too bad with them. I never tried #9 with my old Colt, but #7 is similar in burning rate to Blue Dot, and Blue Dot could very well be a good choice, too. Back then, (30 years ago), HS-7 was also a good choice (same as Winchester 571).

Try some #7 if you can find it. It's good stuff.


You can roll a turd in peanuts, dip it in chocolate, and it still ain't no damn Baby Ruth.
