I’ll look in my load logs when I get off work, text you a pic or two if I find anything exciting. I do recall having great luck with IMR4831, found some data in an old manual and tried it for grins. Good accuracy with 300s and 2550 or so out of my 20” barrel.
My 20" AI loves IMR4831, essentially AA3100 for the 270grTTSX. A number of people have shot their best ever group with this rifle, which is usually the biggest they have ever shot...
