From the Ramshot burn rate chart
I personally would like to find some 571...
Looks like from your selections:
22. Winchester 231
31. Winchester 473AA
33. Winchester WSL
40. Winchester WAP
42. Winchester 540
44. Winchester WSF
48. IMR 800X
56. Alliant Blue Dot
57. Winchester 571
WSF is the 'slowest' you list, but it is still faster than 800X. I find that the powders between 800X and AA#9 are the best 'horsepower' powders for 10mm.
The great thing is YOU can try them all!!!
