Yes, cock on opening like most modern bolt action rifles. If it is really tight, you may want to redo the bolt internal lubrication. I prefer a molebdenum filed grease like Molyslip.I’m hoping any of yall can maybe help me answer a question about my Tikka T3. When I’m just cycling the bolt, it performs as smoothly as ever. When I dry fire, after pulling the trigger, my bolt becomes very stiff and hard to lift. On guy suggested that it’s because Tikka’s are cock on open actions. Is this the reason?
