Guess after I get it all out gonna have to get a replacement bolt and check headspace?
The locking lugs on the bolt head could be seriously set back into the locking shoulders in the receiver.
Is the bolt serial mismatched? It might just be a poorly-hardened bolt installed by the importer. Matching numbered surplus Mosins are generally pretty well-used and should have failed before now however, so in that case I'd want to rule out any ammo-related issue.
A quick internet search shows the apparent number of documented Mosin destructive failures can be counted on one hand.
Any missing fingers on that hand!?!?
sorry - any good opportunity to be a wise-ass is an opportunity I just can't pass up
Your bolt is still locked. Without the bolt handle bar camming the bolts lug that rides there, nothing is rotating it out of lock.
To fail in that place had no pressure, it must have been cracked already. Hopefully your lugs are not set back.
I would pop off the busted piece and work the bolt out, if possible.
Have a good hard look at the case, the base of it, and the primer. Thats where you can see if you have excessive pressures.
Its a rimmed cartridge, the headspace is set on the Rim. You can change bolt or just the bolt head and be just fine.
Get 'er out and post picts!!!
You ever tried removing a barrel from an old Mosin?? Royal pain in the arse!!
I've seen a few twisted recievers from that..
It isn’t more than scrap iron right now, regardless of how difficult it is, you still might have to unscrew the barrel. There are ways to heat actions without ruining them. It’s a problem, no doubt about it. Wasn’t easy getting the barrel off my 1898 Springfield either but I did get it off.
The connecting bar is still engauge and pull the bolt head back once rotated.
Your not going to have to worry about ruining anything except some finish.
Also, dont forget that the extractor is still holding the case, and you will be having to apply some gentle but firm force.
Once the bolt head is rotated up, if it wont pull back out with the bolt, you can always drive out the case and bolt with a rod and a couple smacks.
If your bolt head was set back into the lug areas, you will see other pressure related cracks, folds/stress on the collar, and the lug that would have transferred back to the bolt handle.
The crack seems to be in a way that indicates it was forced up against a stuck case, either over pressured or a dirty "Sticky" chamber. The crack is at a thin point and the lug on the bolt head in the camway could have been what was forced against that piece during bolt lift and unlocking.
Or bolt handle body base was flawed and failed when it did.....
I did also with another one of my Mosin, I/m leaning toward stress caused it to break not ammo. I wasn't the one shooting it at the time my friend was so I don't know what happened, it was getting a bit of sticky bolt after 20 rounds or so which was shot fairly rapidly through it but I have had sticky bolt happen with other Mosin in the past and it wasn't that dirty when we started shooting it that day. Fact is I have put only maybe 150 rounds through it since I bought it 10 years ago and had cleaned it, and it was one of my more smoother running Mosin bolts
The bolt head is the only part of the bolt that contains any pressure aside of a critical failure which would bring the bolt body into gas venting and locking.
The forward part of the bolt root has a number of kinda rectangular cuts. A crack probably originated in there somewhere.
Ive never heard of one....yet.
Would be interesting, for sure. maybe Hatcher blew a couple up in his research?
