It sure sounds like Tikka's to a rifle looney are boring, they don't need much of anything.
One question are the barrels screwed into the action, just encase I would like a different caliber other than what is available in left hand guns ?
What gunsmiths would do the work ?
Thanks CW
Yes, the barrels are easily replaceable. However, most Tikkas shoot lights out. Hopefully, you can choose a cartridge you like from Tikka.
You have several good choices....
