If its still original tikka barrel it should be written on the side, with calibre aswell .

A quick way to find out the twist of any rifle is;

• Get a cleaning rod.
• Put on a mop or other cleaning head. Something that engages the lands/grooves.
• Draw a line with a marker along the top of the rod for about 13 inches.
• Mark 12, 1 inch markers along this line. Crossways so you have a "ladder" effect.
• Place the rod into the bore of the rifle and push it about 3-4 inches down the bore while keeping the 13" line pointed as stright upwards as possible.
• Now slowly push the rod down the rifle until the rod does a full revolution and the line returns to an upward facing position.
• Make a note of the number of inches the rid has gone down the barrel. If its 8, 9 12 then your rifle is an 1:8, 1:9, 1:12.
• All of this is measured from the back of the reciever. Where the bolt would "touch" when closed.
• Do this 2- 4 times to be sure.
