I expect you’ll be considerably better off to purchase a Ruger American, CZ 527, or Howa Mini action rifle in 6.5 Grendel and simply sell the 700 SPS.
Thought about selling the 223 also but it was in the safe maybe worth a try. in the long run may be cheaper but I was looking at a 26inch barrel in heavy contour might be hard to find one.
