Add me to the .22 Creed list. It can do everything the .243 can do if you twist and throat it right and feed it a steady diet of 88 grain ELDMs.

If you are going to build a "duplicate" then my answer is build a 7-08AI. Twist it fast and throat it to shoot the 160 class bullets. Mine will push the 162 grain ELD-X bullets to 2800 out of a 20" barrel.
