9.5-twist is pretty standard for most 7-mags. I've used the 175gr Nosler Partition in my 7mm magnums for years with great results, but these ultra long bullets nowadays are pretty crazy.
I was working on a 145gr LRX load with my last 7-mag, not quite the BC of the 175 ELD-X but still pretty good "modern" design, loaded to 3.340" oal. Last rifle I got them to 3150fps and the drop chart on that was looking pretty tasty.
