Looking for 10MM 180-200Gr Lead bullet Load Data

[SoCal1911]

Looking for Lead bullet load data, using 180Gr Bearcreek Moly coated bullets. I have G20 with 6" KKM Barrel,fully supported chamber.
I have preferred using Accurate #9 powder for plated 180Gr bullets with good results around 1100-1150FPS. Open to other powders too. I have plenty of the BC in stock, wanting an inexpensive practice load. Wanting accurate loads and not Max loads, and avoid leading of the barrel. For range work, punching paper. Not much data out there for lead bullet data in reloading manuals. What is your favorite load?

I use Blue Dot;

Use oregon trail load data, it's the same bullet.

I'm waiting on my new barrel for my XDm 10mm but doing the same thing. Once I slug it I'll order some Montana 200gr hardcast bullets and have the Fab Four of 10mm powders, blue dot, 800x, longshot, and AA#9 waiting for some testing. I ran some loads through the XDM that I had used in my G20 but had a case failure so now waiting on the new barrel with a fully supported chamber before I shoot anymore.

[SoCal1911]

I have decided to use AA#9 powder with 180Gr Moly coated Bearcreek bullet in G20 with 6" KKM Barrel that has fully supported chamber in Starline brass.
11.0 Gr AA#9 estimated 1100FPS 1.245" OAL
11.5 Gr AA#9 estimated 1150FPS 1.245" OAL
*Do not use this load data, your results may vary, may not be safe in your firearm.*Do not use in an unsupported chamber, or Glock stock barrels*.

Since Bluedot is not available, I will try it once available. There is more bluedot data available.

Once I test these loads I will update this post.

Thanks to all that helped, I appreciate your input.

Updates:
Today I shot G20 with KKM 6" barrel,with fully supported chamber with conventional lands and grooves, with 180Gr Moly coated lead Bear Creek bullets:
11.0 Gr AA#9 estimated 1100FPS 1.245" OAL
11.5 Gr AA#9 estimated 1150FPS 1.245" OAL

Zero Leading of the barrel, excellent accuracy, with a tiny bit of unburnt powder, primers a little flat but not excessive.

**Do not use this load data in factory Glock Barrels**
These are my results in my G20, may not be safe in your pistol, use at your own risk. Be smart, work up loads starting low and look for signs of high pressure.

I've got a 6" 10MM kkm in my G21 and use >13.0 of 800x to launch 135 Noslers and ludicrous speed. Very fun. And under max of the old books.
