If i rebarrel from a .223

[Central Desert]

If i rebarrel from a .223 (Remington 700 SA action) to 6BRA will i need to replace the bolt with a .473 bolt face (308) ?

Yes

Or, you could just have the bolt face opened up and a new M16 style extractor installed.

Rem 700's are pretty easy to have the bolt face opened up on and I've had multiple standard bolt face Rem 700's opened up to mag bolt face so I don't know why you couldn't have a 223 bolt face opened up to the .473 size, but like I said, you'll need a new extractor and the pinned M16 type, IMO, are the best to use.

Or you can cut the rims on the 6br . Not hard and allows you to go back .
Or my favorite, the 6 TCU !

Central Dessert, sounds like you need a 6 TCU or a 6/204 Ruger.

The 6mm-204 Improved is an excellent cartridge and very capable of winning any match the the other small 6mm's can.
