I'm working one up right now, though I'm burning up some IMR 4350 before moving to SUPRFORMANCE. I also have a ton of H4831, which is also pretty solid in 6.5 CM. In a rifle I built for my dad, I got HDY 143 ELD-X bullets up to 2950 with no pressure signs on SUPRFORMANCE, but I'm seeing minor cratering on my current loads at 2750 on Berger 153 Hybrids. I am using Rem #7.5 primers in Lapua SR brass right now, so will look into using some of my LR brass for a different result. Remington primers are notoriously soft, so they can be hard to interpret for pressure signs. I realize that's not an answer for your exact question, but I'm more than happy to run numbers in Quickload for you if you like. Just remember that Quickload projections are just that....projections, and the real-world results can vary a lot. This makes it doubly important to start 10% below the projected max and check every fired shell before moving up.
One last random point: the best advice that I've ever gotten on reloading was from one of the staff at GA Precision, who spoke to me for AN HOUR at random dispensing free knowledge. He pointed out that any time you work up a load, you should calculate out how much extra distance/how much less holdover the extra velocity gets you before chasing it with more powder. His point was that TANSTAAFL applies to reloading, and that more pressure will wear your throat faster, which in turn means replacing the barrel sooner. If 2650 FPS gets you what you need, think carefully before trading barrel life for 2750 FPS.
