I run a fast twist 22.250.. with a one in 7 twist..

75 to 80 grain bullets can run at 3350 fps in a 24 inch barrel..

a buddy who has the AI version really isn't getting any more velocity out of his... but then again, he still thinks max velocity in that cartridge lies with 4350 and slower burn rates..
