I believe you are correct, right now the production is .308 Win. and then .30 TC. No info yet on when the smaller calibers will be rolling. They are ramping-up production, have some excellent improvements to the original design. I have not seen the production piece yet but they have come-up with a new detachable magazine and trigger guard assembly. Plus they took some weight off the action so the rifles are a bit lighter. Big news is accuracy, they are shooting very well. There are some interesting new developments, will share info when the time is appropriate.
I had the good fortune to have the opportunity to write a barrel break-in and maintenance instruction sheet that will go with each rifle.
