They came out in Australia in a package deal, 243 and 30/06 with Weaver mounts and a cheap 4x Weaver scope. Had one in 30/06 and it was fine for a bush rifle. Had one gunsmith complain that they were a bit difficult a time to line a scope on because of the accuracy of the holes for mount bases on the action. Have seen one split a stock in two pieces when separated. Still they were good value and you should be able to rechamber to any of the 30/06 family.
