There is a very good base of experience for a 255gr 45 RNFP or SWC at 925 fps or a bit beyond. It's called the 45 Colt and it kills way better than its paper ballistics would indicate. I like both the 10mm cartridges but they're hard pressed to put meat on the ground faster than a proper 250 grain 45 will.
