Out of my purpose-built race gun, I use HS-6 in 9 Major loads to go way, way past that. If you've got the barrel length, 1100 fps should be no sweat for any of the powders people typically use for 9 Major.
ETA: Along with HS-6, some of the common 9 Major powder choices include AA#7, Silhouette, VV N350, 3n37, and 3n38, and AutoComp. Some people have also used CFE. I have experience with just under half of those, but I can confidently say that nobody bothers developing a gamer load with anything that doesn't meter well. The volumes required are way, way too high to even consider something that won't reliably drop on a progressive.
