ShortRifleFan: The Sturm Ruger Company offers a 6.5 Creedmoor Rifle (heavy barrel, stainless) with a 28" (twenty eight inch!) barrel.
You should easily and safely attain that speed with that factory Rifle and that weight bullet.
One of my close friends has one of these "28 inchers" "on order", right now and should take possession within a month.
Good luck in safely attaining your arbitrary goal.
Hold into the wind
