Thread: Tikka 55 twist

  1. #1

    Red face Tikka 55 twist

    Could someone provide me with twist rate of a Tikka M55 22-250? Thanks in advance.

    It's the standard 1 in 14".

    Tikka have always used the same barrels and twist rates in their sporters be they M55, M558, M590, M595, or T3 actions. The same goes for the long-action equivalents. The barrels have retained the same length, taper, and twist over the years ... but the blueing and finish has gone downhill!

    The barrels in the M55/M65 look shorter than those of their successors but that's an illusion because the earlier actions are more compact. I've checked the M65 .308 against a T3 .308, and they are the same tube.

    The only exception to this is the T3 series in .223/5.56mm. As these could have a target shooting use you can now choose a faster 1:8" twist, rather than the standard 1:12" twist which is still on offer.

    Thanks bud, I was hoping it was a 12 twist. Should be good for 50 to 60gr bullets.

    If you have got the rifle to hand, why don't you measure the actual twist? Rgds JCS

    2 full turns in a 22" barrel makes 1in 11/12 twist in my book thats what my Tikka 22-250 chucks out just checked its the continental without moderator (Standard Barrel)
    Done with a tight as a fishers ring piece patch on 22 jag on a rotating rod indexed with a tape flag

    Definitely not 1 in 14

    Thanks !
    I told `Sinistral` on a previous thread that my M55 Continental .22/250 was one-in-twelve but he still wont have it.
    It is like other bum-fodder often posted by those who have not had the practical experience to back it up.
    Over a long period I have had Tikkas in M55, M65, also a couple of T3s, all of which shot to a high degree of accuracy.
    No crow or deer has complained to me yet that the guided `missile` which perforated it came out of the plastic magazine of my T3 .

    I don't know if this is of any help but I keep a bit of a reference library made up of catalogues of various manufacturers. I thought that I might still have one for the M55/M65 range but I don't. I do however have catalogues for both 595/596 and T3 both of which show the twist rate as 1 in 14" for .22-250.

    That may be on the 595/596 but there had been complaints about excessive barrel wear on the 22-250 in m55 thats why they opted for the 1.14 at a later date. they was also susceptable to excessive throat wear as well if shooting cartridges at max velocity, as i am very careful in my loadings in keeping the pressures down a little from the max i have had 30years plus out of mine without any wear as indicated and still groups exceptionally well.

    Thanks for your contributions to this, MS and Hubert. This is odd, as it's not what the Tikkakoski stuff says but you have the real article to hand.

    I've just used the rod method to check out my Tikka .22-250, and got almost 1.5 turns in 20.25" of rifling from the mark so it's the standard 1 in 14 twist. My .223 checks out at about 1.7 turns so is the standard 1 in 12. Thank the Lord for giving us wet Sunday afternoons to resolve issues like these.

    Sounds like that at sometime in its life its been rebarrelled before being screw cut which is common practice with a shot out barrel and they would have used the 1.14 twist
