6ARC Tikka

[HighUintas]

Has anyone actually tested a 308 Tikka bolt face to see if it feeds and extracts reliably with the arc case?

Or would it require a reamed 223 Tikka bolt?

The latter. IMHO the 6 ARC is the best argument for an aftermarket scaled "T2x" receiver with a native Russian bolt face. Use the like button to indicate interest at the $1k price point and I'll go make some machine shop inquiries.

The .308 case head is .473 and the 6 ARC is .441, so a difference of .032. I know you just said feeding and extracting, but I wouldn't be eager to light one off with an unsupported case head like that.

You can have a bushing put in to take a .473 bolt face to fit the arc case.

I wish more folks would just make factory ammo for 6 br.. That is more attractive to me.

I was just going to suggest this one. No need to switch bolt faces, and achieves the same result

I'm confused. How does the bolt face support the case head? I'm not sure why firing a 441 case on a 473 bolt face would be an issue at all.

I'm definitely not talking about firing a 6aec round in a 308 rifle. Only using the 308/473 bolt.

This is why the gay tiger was invented. Problem solved.

Except for the whole factory ammo in most sporting good stores, just like the 6BR. Woulda/coulda/shoulda- the ARC is what we’ve got for a viable factory option.


Getting a Tikka 308 bolt bushed to use the grendal/ARC case isn’t hard, you are already getting a barrel spun on. There will be a couple for S2H rental rifles.
