None yet. Tikka (or Beretta actually) is kinda conservative when it comes to cartridges. They are presumably not going to chamber a rifle in this cartridge until it becomes tried and true for a while. With the exception of the .300WSM and the .270WSM, which already have a following of sorts, virtually all other rifles sold in the US are chambered in tried and true cartridges, like .243, .25-06, 7mm-08, .270, .308, .30-06, .7mm Rem Mag, .300 WM, .338 WM, etc.
