Heavy bolt lift!!
Im getting, what i feel is heavier than normal bolt lift. The thing is, im shooting factory ammo in my 270wsm. Do the tikkas t3s have a little heavier lift than other rifle manufacturers? Its just heavier than what im use to in my Remingtons. Any thoughts? Anyone else have this issue?

bolt lift after firing should not be much more if at all heavier than opening & cocking the bolt on an empty chamber. I would scrub the chamber… and then do it again. Then closely inspect your brass for pressure signs.

Well i feel kind of foolish. I dry fired my rifle and cycled the bolt, i had no idea that the Tikka took so much effort to cock the firing pin. I had been thinking that i had a heavy bolt lift from pressure. The bolt lift is much heavier than my other rifles, maybe the firing pin springs are wearing out on my older rifles. Anyways………… 😛

I just changed my bolt shroud and I had the same effect as you're describing…
Mine was easily fixed by sanding the inside of the shroud in order not to rub against the metal on the bolt.The bolts on Tikkas can be hard to open sometimes and the recipee is normally a good clean on the surface that tensions the spring and putting a bit of grease on this surface afterwards.
This makes it somewhat easier and stops the action from grinding metal. -

You have a PM

Could've written my tip here… ;D
I sanded the inside of my shroud in order to make sure it wasn't rubbing against the metal on the bolt and then placed a small dab of grease on the surface of the piece that actually compresses the spring.
You really don't want dry metal grinding metal here since it can both wear down the metal and cause a heavy bolt lift.
This did it for me anyway!

Bumping this because I'm having the same problem. It's quite extreme though, requiring that I get up over the rifle and use two hands to forcefully lift the bolt. There's no way I can cycle the bolt from a shooting position, it's too stiff to lift, cocking the firing pin back.
Once the firing pin is cocked, there's no more resistance. Cycling in a new cartridge or fired brass is fine, no excess resistance doing that, but once the trigger is pulled or the rifle decocked, lifting the bolt to recock is extremely difficult.
Is there anything I can do to resolve this myself, or do I have to go in on warranty?

Sounds to me like you have an overpressure problem using a cartridge with a too higher charge

The problem persists whether there's a round in the chamber or not, fired or not, it's something directly related to the mechanical cocking action.
The rifle has seen less than 100 rounds of factory ammo since I got it, mostly hornady or nosler match, and I haven't noticed any pierced primers or cratering or anything.
I disassembled the bolt and cleaned it out. There doesn't seem to be any problems with the cocking piece or the ramp on the bolt, but pressing them together and simulating cocking the firing pin by hand, it definitely feels gritty despite the surfaces being smooth and undamaged. Lube and light sanding didn't seem to have any effect.

Bluh, so the problem was just lubrication… I was using a heavy oil since it was all I had on hand while cleaning and it was wholly inadequate. A nice grease with anti-seize smoothed and lightened it out to the point where the cocking lift is almost as light as closing the bolt on a round.
I feel so stupid right now, but at least it's a relieved stupid.
-
Glad you got it sorted , everybody does something stupid now and again

Doesn't hurt anything…and helps a bunch, to keep the bolt mechanism lubricated with a good bolt grease.
A stiff bolt lift is normal. Remember, the cartridge has been fired, and there is case expansion to deal with.
