I study firearm design and have for decades and the OP made some valid points. The older machinery, no matter how good couldnt hold the tolerences of the new CNC machines. This one point isnt the end of the story. The barrel nut system used on the Savage and now Marlin bolt action is interesting and has proven itself in the accuracy department. However what the OP didnt mention was the fact that this was designed to be the cheapest way to manyfacture a barreled action. When Savage came up with this idea their major concern was, how to build a rifle so cheap as to have a maket advantage. Thus they built the model 110. The rifle got its model number by the price they charged for the gun $110. This system requires very little skilled labor, thus lower wages. I saw a program on Rugers 10/22 factory. Not a skilled person was observed. A total assembly line process. The steel quality of barrels is superb in newer guns, and accuracy from closer tollerences is breaking records daily. Again however, this doesnt not end the story of modern manufacture versus past manufacture. From what I can assern, the entire machining of quite a number of modern guns consist of fewer that 35 operations. I derived this fiqure myself from observations of construction design, it is not set in stone but is close. The machining operations required to build the rear sight alone on a 1898 Krag was 44 operations. Far more quality machining in older guns, mostly milled from billets of steel. Newer guns are cast, stamped tin, MIM, and plastic. As for the bolt on the Savage, while functional and an aid to increased accuracy, it was built and designed to be the cheapest possible. It works quite well I am told but this multi piece bolt is a far cry from the old machined bolts of the past. No bolt handle cant fall off the old model 70's as the were machined intergrally. No front sight to fall off as these were machined into the barrel as well. I would far prefer an older all machined steel gun that is only capable of 1 1/2" groups to a modern gun capable of 1/2" groups if hunting or survival was the purpose of the gun.
