he Savage Model 10 BAS-K Police/Tactical is dramatic and impressive-looking with its “assault rifle” look, adjustable stock, separate pistol grip, muzzlebrake and forearm complete with accessory rails. Its purpose, though, is not to deliver firepower but to deliver extreme accuracy, and that it does. It’s funny sometimes how things work out. An objective of the Savage design was economical manufacture. Earlier Mauser receivers had been made on forgings, with many tedious milling operations requiring skilled machine work. The Savage receivers are made from sections of steel tubing. The only milling operations required were for bolt operation, and openings for the loading port, magazine and trigger mechanism. Round actions like the Savage 110, made of heavy gauge steel, are inherently rigid. They are relatively easy to manufacture so the entire receiver/barrel unit is straight, square and concentric. It adds up to consistency, and consistency leads to accuracy. The bolt is an assembly of several components. The main body of the bolt is a section of steel tubing. The 110 locking lugs are integral with a piece of steel which is inserted in the front of the bolt body and secured by a heavy cross pin. Due to the tolerances involved there is a bit of play; not much, but enough to be perceptible. I wonder sometimes if this may not be another factor in the Savage’s accuracy. Incidentally what appears to be a second set of lugs behind the locking lugs is actually a baffle, which blocks off the lug raceways in the receiver when the bolt is closed. Its purpose is to reduce the volume of gas rushing back into the receiver in the event of a cartridge case failure. Savage’s method of setting headspace, designed to be a labor and cost saver, also has the potential to improve accuracy. The old way was to screw the barrel tightly into the receiver, cut the chamber with a chambering reamer, then insert a headspace gauge and close the bolt. If the bolt wouldn’t close the worker would cut the chamber a little deeper and try again. With patience and time this cut-andtry process would eventually result in a minimum tolerance chamber. Since time costs money the temptation is to cut the chamber deep enough with the first or second pass; not so far as to cause excess headspace, but enough so accuracy potential is reduced. With the Savage 110 system the chamber can be cut first, then the barrel can be spun into the receiver with a headspace gauge in place.

The Savage rifle functioned reliably, bolt operation was smooth and dependable. Dave would like to see a stronger spring on the magazine catch assembly (below), as he bumped it a couple of times while handling the rifle and unintentionally dropped the 10-shot mag.
