New Bolt Gun Build - First time not buying every part myself - What bolt face diameter?

[peaceatwar]

I'm in the process of building a new bolt gun in 6.5 CM.

I have started the wait on a sentinel chassis (Lefty) and I'm putting the finishing touches on a Deviant Action build from Defiance.

My only question is I don't know what bolt face I need?

What are some go to bolt face diameters in custom actions? I apologize if this is a noob question but I am totally clueless. Any help is appreciated.

The default on my PO is .480

Short actions with a bolt face .Dia of .470 +/-.... .473

The bolt for my creedmoor is a .484 from pt&g.

Standard 308 win boltface is what you need for the 6.5 CM
