Quality , Speed , or Inexpensive
You only get to choose two of the three . These pieces are labors of love . I waited 6 months for Obermeyer to complete the barrel , then another 4 months at the gunsmith . Was worth every minute of the wait and you will be happy that you didn't shortcut the build in the end .
Plus it will give you some time to save for the optic , don't shortcut that either . They hold value , just as a firearm does . And if your dead set on 7 mag , your gonna want a good brake as shooting 50 plus rounds in a session would be rather brutal , I know I would pick up a flinch after 20 or so
