Adapting a .308 bolt face to a .223 face?

[FN in MT]

Is it possible to fit a bushing to allow a .308 size bolt face so one can use of a .223
Rem ctg on that bolt? Pro's/ Cons?

I'm aware PTG has replacement bolts but really don't want to wait 6-12 weeks.

No problem if you can extract the case

I do that and the opposite all the time; 308 to 223, 223 to 308, etc.

Where does one buy the bushings? I have a great smith who works quickly and cheaply. When we do a project I like to have the required parts on hand, so it's as painless as possible for him.

Appreciate the replies.

Bushing and a Sako extractor would be easy enough work, but does anyone know if it'll eject reliably with the ejector moved so far outward? I'm positive it would work as a single shot, non-eject model. Another option that will work and eject is a Savage bolt head conversion.--Mike

You have to make your own bushings. It will extract. Be careful, if your smith has not done one of these before.

But will it eject?

I don't mean to blurt in on the OP's post but I was bout to ask a question that might help him out also.
I have a 308 Savage target action that I changed the bolt head to a PTG 223 head with smaller firing pin. I can't seem to run the same speeds as others with a straight 223 action without getting pressure. I have to run the node below them or I blow primers. My firing pin seems to drop very hard, my ejector throws the cases 2 feet, and I get slightly cratered primers on all loads. I'm assuming since this was a 308 Bolt originally the spring on the ejector and firing pin are more stout. Could this be the reason I see pressure signs quicker than others?

Nah, any number of reasons may be the cause of pressure, but a contributing factor to cratered and pierced primers with a Savage is the bolt face isn't flat. They're often somewhat concave around the fp hole.
Usually, truing the bolt face cures what I think you're describing. This is on a Savage. Remmy's have different issues that cause similar problems. If the only pressure sign you're seeing is cratered primers, you may well not be having pressure problems at all.

jsthtn247,

Send your bolt to Gre-Tan Rifles to get the firing pin hole bushed, and the pin turned to fit. It will become a 'set', and you won't want to swap the parts around any more, but it will cure the problem (big hole / little firing pin).

The placement of the ejector pin on all of the Remington 700's is in the same place except for the Fireball. The answer is yes.

Thank you. I didn't realize that they were in the same location.
