Default 200gr JHP in 10mm

I recently acquired 1k of 200gr JHP. All I have shot in my 10mm is 135gr Frangible FN and 165gr JFP/JRN. I have 500 Starline cases that should be arriving sometime this next week. I am wanting to push these at least 1100fps. Except for conflicting data I am leaning HS-6, CFEp, or Blue Dot mostly because I have those in stock and they should be able to make the numbers. Any suggestions on a 200gr JHP load?

My Lyman 48th on 200 gr JHP
800X start 5.9gr 963fps max 7.6gr 1119fps
HS-6 start 7.5gr 987fps max 8.6gr 1126fps ^
AA#7 start 9gr 987fps max 10.6gr 1145fps
Blue Dot start 8gr 1015fps max 9.6gr 1148fps *

My Hornady 4th on 200 gr JHP
800X max 8gr 1150fps
HS-6 max 8.2gr 1050fps ^
AA#7 max 9.5gr 1150fps
Blue Dot max 8.9gr 1150fps *

My Speer manual is too old for 10mm.

Hodgdon Web page on 200gr HDY FMJ
HS-6 max 8.6 @ 1089fps ^
CFEp max 7.1 @ 1123fps
Universal max 5.9 @ 1015fps
HP-38 max 5.6 @ 1011fps

Vihtavuori web has N105 for 200gr bullet 8.2 @ 1111 gr.
