• Savage Bolt Race Dimensions


    The bolt race dimensions on an SA Savage action.

    Major Diameter: 1.005-1.015"
    Raceway Width: .445-.450"
    Bore Diameter: .700-.703"

    Minimum amount of clearance between the bolt body and bolt race bore diameter.
    Most custom actions have .0015" clearance.

    Most Savage bolt bodies measure .695-.697 and are pretty consistent, but I can't say that about the receiver bores. Even though the print calls for .700-.703" bore diameter, I've found many larger than that. The largest I measured was .712".

    You have to remember that the receivers warp some during heat treat and close tolerances aren't applicable. Custom actions have the bore and raceway wire EDM'd and are within .0002" of being perfectly straight and true, whereas Savage actions have the bore drilled and the raceway is cut by drawing a series of broaches through the action's bore.
