    comments : Hello! Why all the Free Bore in the Sako Finnlite and Tikka
    300WSM? My brand new Sako 300WSM and also my sons Tikka 300WSM have poor
    accuracy most likely due to this so why do this? To get reasonable
    accuracy
    I will need to rebarrel these rifles at my own expense, sending them
    back is
    a long drawn out frustrating affair, I\'m very disappointed!


    From Sako
    ALL RIFLES BY ALL MANUFACTURERS ARE BUILT WITH CHAMBER AND BORE
    DIMENSIONS THAT ARE STANDARDIZED WITHIN THE INDUSTRY. THIS IS TO ENSURE
    THAT ALL RIFLES (FROM ANY MANUFACTURER) WILL SAFELY CHAMBER AND FIRE
    AMMO FROM ANY MANUFACTURER. THE EUROPEAN C.I.P. STANDARD IS (OR CAN BE)
    SLIGHTLY DIFFERENT THAN THE AMERICAN S.A.A.M.I. STANDARD BUT, IF THERE
    IS A DIFFERENCE, IT IS ONLY A VERY FEW TEN THOUSANDTHS OF AN INCH. FOR
    ALL INTENTS AND PURPOSES, THESE DIMENSIONS ARE IDENTICAL. GENERALLY, IN
    THE CASE OF A MODERN HIGH INTENSITY CARTRIDGE, THE AMMO IS LOADED TO
    NEAR MAXIMUM PRESSURE SO THE THROAT LENGTH WILL BE LONG ENOUGH TO ENSURE
    PRESSURE CANNOT GO BEYOND SAFE LIMITS.

    Is this fact or nonsense? Anybody having any problems with pressure when loading close to the lands? If I had known you had to have freebore like this to use the 300WSM case I would never have bought these rifles. What about other manufacturers? are they cutting extra freebore into there chambers? /ubbthreads/images/graemlins/confused.gif
