300WSM Tikka/Finnlite freebore problem or safety feature?
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
I will need to rebarrel these rifles at my own expense, sending them
a long drawn out frustrating affair, I\'m very disappointed!
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?
