I've this last week bought a 2nd hand tikka t3 which came screwcut.
One of the reasons I went for it was that it was cut 1/2 inch unf, which is the same as my m595 and my intention for the forseeable was to swap my T12 between the two.
I've taken the rear bush off the T12 and tried it on the T3. It screws on reasonably well, but the barrel is pushed up against the side of the mod. I've tried the m595 without the bush to compare and it is central.
Any input as to what has gone wrong? Has the screw cutting been done at an angle to the bore and would recrowning resolve this?
