I have a M11 Action that is originally a 300 WSM. I had thought to rebarrel to 7 WSM or even 7 RSAUM. I've given up on that idea (at least temporarily) to look at rebarelling this to a 6.5 Creedmoor.

I know that the bolt head needs to be replaced. What about the firing pin? Anything else that needs to be replaced? Magazine? It is currently a stagger fed and don't plan to add bottom metal till I move it to a chasis stock which is still a little ways down the road.

I'm looking to order parts within the next few weeks so want to nail down all of the miscellaneous stuff as soon as possible.
