I'm going to begin acquiring the parts to do a 6.5 Creedmoor build very soon. Actually, I already bought the dies and case length gage. Was getting dies for a .357, so I ordered the Creedmoors too. I have a bit of confusion in my mind concerning bolts. Let's say I find a good deal on a used .308 or .243 or 7 .08 - will that bolt work for the Creedmoor or do I have to buy another bolt? I know the aforementioned calibers are all .308 cases. I'm just confused about how a different size case would work with that bolt face. Can someone lay that out for me, please?
