Tikka ARC conversion

[General RE LEE]

Just get a Howa Mini barreled action from Brownells. See how it shoots. Bell and Carlson makes hunting stocks for the Mini that are around $350.

I wouldn’t go down the Tikka rabbit hole with a 6 ARC due to the bolt face.

And if there is any case sticking during primary extraction, what happens now? You're the first proponent I've ever heard of this, and it's ridiculous.

Go ahead and run it if you so desire. To the rest of anyone else on here with common sense, DON'T use the incorrect bolt face for the case head.

Benchrest shooters have been using standard bolt face, sako style ejectors on 6 ppc for decades.

I saw the inquiry as a "how would it work" or "what would happen" inquiry rather than any indication that standard bolt face was going to be the defacto best way forward.

Sako style I could see it grabbing the rim as they're a very large extractor, Remington or m16, way less grip.

Benchrest guys also shoot single shot for the majority, from squeaky clean covered shooting benches, have their cleaning kits and tools right there if needed. It's unwise to risk this from a field gun that'll get dirty and be ran in all weather conditions.

If you chose to do so, proceed at your own risk. Doing so would be running a huge risk, primary extraction is something that has to happens, every time you open the bolt, no matter what. This is just cutting a corner that'll eventually cost you.

I just tried extracting spent brass with my ARC bolt and it didn’t work

Silly question, but was that from an arc chamber?

If anyone has opened up a Tikka 223 to an ARC, would be possible for you to try and see if it will still extract a 223.
I would expect it to still work as a switch barrel, but you never know until you try it.
TIA

Just put my t3 arc (.445) bolt in my t3 223rem and fed a few rounds, it doesn't work. It will pull cases an inch or so out of the chamber and pulls off of them. I think once the case is pulled far enough out of the chamber to move horizontally in the bolt face the ejector pressure pushes out and away from the extractor side of the bolt face.

Thank you both for the feedback, much appreciated
