Take a depth mike and measure the depth from the front of the action, to the inside ring. Check this
against the measurement of .062 that you turned on the thread shank. The thread shank should be .003
longer than the measurement from the face of the action to the ring.
When you tighten the barrel up on the action, you will see the compression marks on the face of the
barrel. When you have this, the barrel is completed except chambering.
CHAMBERING THE BARREL
The reamers are easily made. If you can make barrel reamers, you can make chambering reamers.
What you need now is a 308 Winchester chambering (finish), and head space gauges (go and no
go).
You will need a 7/16 drill bit, unless you are planning to use a roughing reamer to remove the extra
metal. You will need now to chuck the barrel on the shank in front of the threads. Using a dial indicator
be sure the barrel is running true on both ends.
