My first choice would be AA#9 because it is a really slow burning powder for this appication meaning a 180 gr. bullet. Next in line to AA#9 would be 2400 which is nearly as slow burning, and also works well with heavier bullets for the 10mm. And though Blue Dot will get you into some higher end performce, it isn't as slow burning as 2400 or AA#9 which makes it less desireable to use with the heavier 180 gr. bullets. If you were using the 165 gr. or lighter bullets, Blue Dot or AA#7 would be exceptional choices for both velocity and load density.
Here is some load data that might be helpful for the 10mm using a 180 gr. XTP-HP:
Recomended OAL 1.260"
Primer - Win. WLP
AA#9 - 11.5 grs. - 14.9 grs.
Estimated velocity - 950 fps - 1250 fps
AA#7 - 9.3 grs. - 12.0 grs.
Est. Velocity - 950 fps - 1200 fps
Blue Dot - 7.5 grs. - 10.7 grs.
Est. Velocity- 950 fps - 1250 fps
I didn't find any data in my books using 2400 with a Hornady bullet, but I'm guessing it has nothing to do with it being an unacceptable component match. Below is some data for 2400 with a 180 gr. Speer Gold Dot or Speer TMJ.
OAL - 1.250" is recomended for both, Gold Dot & TMJ
2400 - 11.5 grs. - 12.8 grs.
Est. Velocity - 1051 fps - 1214 fps.
CCI-350 primer is recomended in this application and with several other primer's, according to Speer. However, Alliant data indicates a CCI-300 with the 180 gr. Gold Dot with 2400. Go figure, when do we ever find two different data sources that match grain for grain, primer for primer, and OAL.
I don't load for a 10mm so I'm not well informed regarding primer's that perform best with the powder's listed above. I did however find that Speer's data confilcts with other data such as Hornady and Sierra regarding primer's. Good luck and work up safely by loading a few in increments and using magnum and standard primers with each powder charge increment so you can determine which is best suited.
