Once again kicking a rifle idea around. I have gone thru all the threads regarding the 223, 6.5, 6mm/243, 7mm-08 and think I have decided to go 6mm Creedmoor. For my needs it seems like it work perfectly. Only issue is not many factory offerings. I'm kicking around the idea of buying a stainless tikka in a non-magnum short action caliber and having unknown munititions do the work. If you were putting together a 6mm Creedmoor which barrel length and twist rate would you go with
