I had three factory 7-08s with 24" barrels, one was a Winchester "Super Shadow", one was a Remington SPS, and one was a factory takeoff barrel off of a Rem 700 Ti Alaskan. Still have the 24" fluted barrel of the Alaskan, it's been reamed to 7-08AI and is now in the SPS action and a Bansner HiTech stock. Wife took a nice 7x8 bull in NM in 2015 with that combo at 405 yds using 120 gr TTSX. You can add about 40-50 fps to what you're seeing with a 22" barrel.
And PS, you don't have to hot rod the AI to get 2900 fps+ easily with 140 grainers. I'm not looking for max velocity, just a good decent velocity and best accuracy.
God bless and good hunting.
