a machinist can build an accurate barrelled action if he knows the dimensions even thought he is not a gunsmith. given good components, drop a custom trigger in it and a good fitting(or bedded)stock and you will have a shooter.the machine work in blue printing actions,threading,chambering and headspacing is(to quote a talented machinist)not rocket science. Very basic skill involved .We rifle builders like to keep it as magical as we can.Good for jog security.

"We are building a dictatorship of relativism which recoqnizes nothing as definitive and whose ultimate goal consists solely of ones own self ego and desires."Cardinal Rathzinger
