    Head scratching time

    Evening all,just picked up a new tikka t3 lite in 308.Made up a dummy round to sammi spec and tried to chamber the round but the bolt would not close so set the seating die in a turn and tried again,still no closing the bolt,carried on adjusting depth but no joy.Pulled the bullet 150sp and full length resized the case.Tried just the case this time and no joy again.
    Case length is fine and looked in the chamber but can't see an obvious obstruction.
    Anyone had this before or can offer any ideas as to what's going on?
    Thanks all
    rather confused dave
    Just closed the bolt with some effort and as you can see in the photo it has polished an area where it is printed 308win,there is also brass colour left on the face of the bolt?
    something is wrong.

    This problem with Tikka's has come up before. The chambers do seem to be tight compared to other makes.

    With USA dies all the once-fired cases I use for mine need resizing right down, with the FLRSZ die hard up against the shellholder. There's no footling about with quarter turns to get a nip fit. It seems to be all or nothing, but this does make life easier in a way.
    If I'm going to be accused of it then it's just as well I did it.

    You never had this problem with Parker Hales

    How does factory fit?
    Knowledge is knowing that a tomato is a fruit. Wisdom is not using it in a fruit salad.

    Amateurs practice until they get it right. Professionals practice until they never get it wrong.

    I have a motto, New gun new brass, fired brass from one chamber seldom chambers in another, even after F/L sizing.
    This is becuse the portion of brass called the web just infront of the extractor groove is never sized due to the thickness of the top of the shell holder and the radius on the die mouth.
    The only way to overcome this is to use small base dies.

    BINGO,sat the die tight to the ram and resized but still nothing,gave it a extra little nip and bingo chambered sweet as a whistle

    Brass was only once fired so assumed it hadn't stretched too much.Problem solved now.

    I use all sorts of once-fired, and have never needed to resort to special dies. Small-base dies are good for AR15 actions which don't have the camming power or extraction force of a bolt-action.

    Sometimes switching to another make of shellholder in the press does the trick. There are minor differences between them, and dies are designed to match up with shellholders of the same brand. This is the cheapest solution to try first.
    If I'm going to be accused of it then it's just as well I did it.

    It would appear as mentioned in another thread that the difference between SAMMI and CIP in the cartridge specifications ARE THE problem.
