Many thanks 'private fraser' for the link to measure, I will try it. Mine is not printed on the barrel as you suggest, Triffid. The barrel is marked thus :- CAL 223 REM. MADE IN FINLAND. insignia of left facing 'lion' then 3/4" gap, BNP , what looks like crossed hammers with digits 0, 1, 7 left to right then BNP. On the receiver it's marked TIKKA T3 433519 with the small lion figure again. There is no 12 or 8 after the .223 REM. Is my one an odd or have they changed the markings ? Hope I am not s*dd*ng up the thread.
Have measured twist as per link, thanks 'private fraser', and it turns out it's 1:12, barrel definitely not marked with rate, perhaps mine's an early one and they didn't bother then. Would explain why it shoots 55's ok.
My T3 didn't have twist rate stamped on barrel either and yes it turned out to be an earlier one.
There is an email address to check when your rifle left the dealer. Let me know if you want it and I will check back.
Send me pm if you do.
1-10 works well for me
I have a 20" 1:12" barrel which shoots 60gn Vmax bullets well, but my bullets of choice are the 40gn BT and 53gn Vmax. I'm interested in the 1:8" for some long range target shooting, but would be very disappointed if I couldn't shoot varmint weight bullets at decent velocities.
