Bolt takes out row of teeth

I'll try to get more details, next time I see Tommy, but I remember him saying the handle was down, but it tore out of the action anyway.

I assume the handle was still on the bolt, as that is what messed up his face so badly.

I do not know what sort of rough treatment the rifle had seen, but I did ask about reloads, and he said no, and it was new this season. I could only guess the pin had a defect, or was broken during installation, who knows on a $259 dollar rifle.

The Savage bolt head has a keyway in the tenon and a little lug inside the bolt body which engages the key slot. The bolt head can only go one one way and as you said, both the pin and the little lug would have to fail in order to close the bolt without the lugs locking. I think the bolt handle would break first (they break a little too easily). Are the Savage bolts not still made this way?

The bolthead shafts and bolt bodies were keyed at one time to prevent the bolt heads being installed upside down, during assembly, but was dropped. When that change was made I can' tell you.

Another change was the firing pin shank and retaining pin hole diameter. Originally the pins were .145", but for rifles in mag calibers it was reduced to .095" for additional strength. As of 2001, all are .095".

LEFT-handed shooter, RIGHT-handed rifle........ I can't see the confusion. I shoot this way.

That "hammer in the teeth" analogy seems pretty accurate.

Exactly WHY I only shoot LH action firearms. I'm even a bit squirrely using autoloaders such as anything military or 10/22.
Man, hope that guy is ok

bolt

Browning Bolt heads are held to the body by a pin.

Remington had a lawsuit over the 721model? as the bolt head was soldered to the bolt body and the solder let go ,the bolt handle went down as if locked up but the locking lugs did not turn and engage,the gun fired with out being in battery and killed a fellow.

You can't see it most of the time but Remington 700 bolts are soldered in also and use a cross pin. As many times as I've seen people using hammers on bolt handles they must be pretty strong. There's a 1/2" of contact area in the soldered area. The handle is the weak link and will come off first.

Is this really true or an internet story...?

I ask this because I am not aware of any recall of 721 rifles to have the bolts replaced... and I am sure Remington would have recalled to cover their butts...

Thanks for that info. I always assumed that the bolt head was welded to the bolt body. Learn something every day........jackie

I recalled this from gunsmith school at Colorado school of trades in the 80's.It was told by DOC. KRECHO (I don't remember the spelling of his name).It was apparently part of the reason for pinning and soldering on the 700 bolts.

We were given instructions to pin the bolt if we worked on them.It may not have been the 721 series but of that era.I would have to go find my old notes to find the exact model.

bolt failure

I would assume that the pin did not break or come out. It would seem to me that the bolt head probably broke where the pin goes through. That would allow bolt body of the mossberg or the savage or any other bolt of that design to rotate while not moving the bolt head. As Dave said the bolt handle on a remington still would have caught, however I don't think the savage bolt handle drops into a slot and I have no idea about the Mossberg.

I can't remember the exact construction of the Mossberg bolt, but for the bolt head to break on the Savage or for the pin that holds the bolt head to the body to break would require some pretty abusive treatment IMHO. I also sort of doubt that the silver soldered bolt handle on a Remington would stop the bolt from coming out the back in the event of a major failure up front. It's not quite a safety lug like a one piece bolt handle/body would be.
 
The Savage has a full slot for the bolted on handle and the handle is a square .445" at that location. The Mossberg has almost nothing behind the soldered on handle.

You couldn't break the Savage bolt head if you tried to. If the Mossberg head did, it would undoubtedly be at the crosspin hole. If so, when the handle rotated the bolt body, the bolt body would be forced back because of the 1/2 hole shape against the pin and therefore firing pin would never reach the primer. If you cut the head apart on a Savage and tried this, it wouldn't turn because the slot for the handle won't allow the bolt body to move back.


On a different rifle, this happened last night.

Mauser 96 cock on close, nice M70 stock on it with a hinged floor plate. It was built buy one of the guys here I shoot with and it worked well enough out to the 600 we have. I had the bolt apart checking things before and was considering a cock on opening kit, never did bother. Didn't notice anything wrong functionally.

I give it to a young lad so he can shoot something with us. Then I asked him to hand it back for one more check. I absolutely kid you not, it released as I started to turn the handle down. :eek:

Installed the COO sleeve and new spring, needed to remove a tremendous amount of material off the trigger housing in order to add engagement. The trigger was a Timney. I placed a piece of tape over a flat bladed screwdriver tip to use as a pry. Lifting up the sleeve even a hair would release the firing pin previously.

All is well now.

I may weld a profiled "washer" onto the shroud so it will deflect gas away from the shooters face if something let go. The M98 has a much larger shroud face than the M96 for this reason. If I do that, then I won't worry about it.

Cheers
 
Update

Can the original thread starter update us on what really happened. Maybe photos of the gun? The situation described doesn't seem able to happen.
 
I wonder myself

I've never seen a Mossberg bolt head/cocking piece/bolt handle arrangements, but as I've said before I've some doubts about the bolt head pin to sheare and to come out "completely clear" for the two parts to rotate separately.

However, I could see a much clear picture of the firing pin/cocking piece (pin?) to fail and let the firing pin to fall independently to the rest of the bolt head/bolt body cocking cam/bolt handle to ignite the primer.

However, this is just my speculation and without pictures I don't have anything to justify it.

Shoot better
