My shooting buddy used that combo a couple summers ago to scoot 75 Amax's at 3550 fps. We took it out to 1200 yards and it was impressive. I believe his barrel was 26" or so, maybe even more, and a 9" twist. Bullets were stable at 5,000 and 7,700 feet ASL.
He toasted the throat running so many of those suckers, and sometimes very rapidly, and is currently shopping for a new tube for this summer to run the same setup.(except with ELD's, of course...)
