Reply With QuoteDo you have a CRF bolt head?
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.

It's better to shoot for the moon and hit the fencepost than to shoot for the fencepost and hit the ground!
Don't all WSM actions have CRF bolt heads?Originally Posted by BobT
If it is a stagger feed is should be CRF. If it is, you'll have to take out the standing ejector.
Yes, you'll need a new firing pin assembly along with your new bolt head.
A new magazine will be a good idea too just give the best odds of feeding correctly.

No, the center feed WSM's are push feed.

With the info above, would I better off looking for a 308 based action and use that as a starting point? I have a line on one and may just pick it up and have a better starting point. I'll save this action for a 7 RSAUM build later this year or early next.
The assembly is just a few dollars more than the bare pin. It's worth it to me just to be able to swap out assemblies. Especially since you need to take out the assembly to swap heads.
The only problem with the push feed WSM bolt head is finding them. Nobody lists them online.

If you do that the swap becomes a barrel and just possibly a magazine. The 6.5 Creedmoor might feed from a .308 magazine but the lips might need to be tweaked a bit or the follower swapped out.
I just committed to buying that 308 based action. I want something easy and I can always use the WSM action for a WSM round or just sell it. I'm pretty sure I can get what I have into it and it'll be a wash.If you do that the swap becomes a barrel and just possibly a magazine.

Not all of them!No, the center feed WSM's are push feed.

No tweaking required ! Use a short action standard cartridge ( .308 / .243 ) magazine. That's what Savage did on my 12 LRP.If you do that the swap becomes a barrel and just possibly a magazine.

True, but they are not very common are they?

I really don't know but the WSM action I have is a large shank, CRF, center feed.True, but they are not very common are they?
I am really not up to speed on the center feed actions or the CRF actions either one.

Im starting a build turning my M11 300wsm into a 6.5/284 The barrel is already ordered and I had talked with jim at nss, I knew I had to change out the bolt head and already found the part at midway. I was under the impression my wsm was a CRF now im a little confused, how do you tell the difference between push feed and CRF? thanks Jay.
Here you go Jay,
The one on the left is a push feed, the right is a CRF, note the slot for the standing ejector.

thank you so much Bob, so I know my 116 is push feed and I will have to wait a week to check my wsm as its being blueprinted right now. but if I can remember correctly I believe it is a push feed also, But not 100% sure. I really do thank you for taking the time to help out. Thats why I love this site! Jay
No problem Jay, I'm glad I could help. Actually it was a little tricky trying to hold 2 bolts in one hand and take the picture with the other one ;D
