I purchsed a Mexican large ring intermediate length action made by FN. I think it's referred to as a Mexican FN24.

I disassembled the bolt and measured the bolt length from the rear of the bolt to the end of the protrusion at the bolt face (with the ejector slot). The length measured is 6.08".

In the Reference Material link it says the length for the Mex FN24 should be 6.165" and 6.08" for the small ring Mexican 98 mausers.

The bolt locks up fine in the receiver.

Why would it if it's supposedly too short?

Is the distance from the rear of the bolt to the rear of the locking lugs the same (on the FN24 and the small ring Mexicans) and the difference in length is "forward" of the locking lugs?

Do I need to find a new bolt?

Any help is appreciated.

Thanks,

David

I would put some Di-Chem on the lugs and work the action to see that the lugs are getting supported.

If the bolt fits, wear it.

Why don't you try measuring the distance from the receiver face to the bolt face then measure the distance from receiver face to the inner torque shoulder and subtract the latter from the former. If this distance is much more than about .110" then you may have a Mexican 1910 or 36 bolt and not a standard intermediate bolt. The result of using the wrong bolt will be too much unsupported case head. Not a good thing. There are work arounds but you'd be best served by just finding an intermediate bolt.

Thanks for the replys.

I found this link:

http://www.hoosiergunworks.com/catalog/mauser_reference.html

According to the measurements listed (which I assume are not super precise) I also have an intermediate length firing pin, and extractor for standard and intermediate length bolts.

I'm even more confused, but upon reassembly I saw that the firing pin stuck out of the bolt face more than I remember seeing on other Mausers. It must be a small ring Mexican 98 bolt.

Will a Turk 1903 bolt work (same length as the Mex M24)? I read some where else that because of something with the bolt handle, they may not work.

David

A Turk 1903 bolt will work. Unlike the yugo intermediates it doesn't have the safety breech features.

DKim, I have a 24 Mexican action with a matching bolt. I'll take measurements tomorrow for you. IIRC it takes the same bolt an the 1910 and 36.

No, it doesn't.

The distance from rear of bolt to rear of locking lugs is the same. But from there forward the 1910 & 1936 is shorter.

OK, I measaured several bolts out of actions that all serial nos. match and I can find no discernable difference between the Mex 24 and 1910 as far as the bolt bodies go (they both measure .525 from the back of the locking lugs to the bolt face).

My Yugos and 03 Turks both measured .625 from the back of the locking lugs to the bolt face.

Both of the Mexicans measured 6.080 for the total length.

All 4 bolts measured the same from the back of the locking lugs to the back of the bolt, so, theoretically they should interchange. The barrel would have to be installed to whatever bolt you were using.

Rojelio

PS: I think that 6.165 is the measurement for a standard FN24. That's also what my 03 Turk measures.

As some have reminded me, Jim Wisener himself pointed out to me that one has to "do things" to make a turk bolt work.

Essentally you make it a safety breach.

Some may say differently, but, after Mike and Jim directed me to try, and I did, there is NO WAY a turk bolt will fit into a BARRELED mexican action. you would shear off the bolt handle and STILL not have it in, if the rifle was barreled for a mexican bolt

Sure, it can be fixed, but it is not a standard.

live and learn.. I certain took the information from those that know more than me.

Yes Jeffe, I agree.

as I said in my post the barrel would have to be machined to work with whatever bolt you are using. They are not interchangable unless you are rebarrelling or setting up your existing barrel to work with the bolt.

Rojelio

Thank you everyone. Thanks Rojelio for taking measurements. Pretty interesting the Mexican 98's (both small and large ring intermediate length) have the same bolt body length.

I'll take some pictures. In particular the view looking in from the receiver ring at the bolt face.

David

DKim,

Have you measured the distance to the bolt face from the receiver ring yet?

In the end, this is all that matters. Do the guides on either side of the the ejector slot protrude beyond the torque shoulder?

Well the pictures wern't well focused but I did take measurements. From the bolt face to the outside (side facing the barrel if installed) of the inner shoulder I measured .21 inches. There is also a visible gap between the inside of the shoulder and the bolt face.

The firing pin sticks out .11 inches from the bolt face.

I'm pretty sure I need a new bolt.

Thanks for the help. Any more input would be appreciated.

David

Jeffosso,

When you say a 1903 Turk bolt won't work in a Mex barreled action do you mean a small ring (1910 or 1936)? It seems from the dimensions on the reference chart that it should work for a Mex large ring. The bolt lengths listed are the same.

Thanks,
David

DKim,

I'm having trouble visualizing where this gap is that you're talking about.

If the front of the extractor and the front of the split ejector guide protrusions extend to within a few thous. of the front surface of the torque shoulder, then you have the correct bolt.

If they go beyond the front surface of the torque shoulder, then you have the wrong bolt. It's that simple.

Rojelio

What Jeffe means is that with a Turk bolt, the bolt face will be flush with the front edge of the torque shoulder. Everything forward of the bolt face will be protruding beyond the torque shoulder, Which will not allow the barrel to be screwed up tight against the torque shoulder.

Rojelio,

There is definitely more than a few thousands from the front of the extractor and split ejector guide protrusion to the front of the torque shoulder (I'm assuming front means the side facing the barrel). It's about .10 inch.

I think this makes sense. If the correct bolt is supposed to be 6.165" and mine is 6.08" then this difference (.085"). If this is subtrtacted from the .10" above, that would bring the split ejector guide protrusion very close to the front of the torque shoulder.

If I understand you correctly, I see why the Turk bolt will not work in a Mex small ring 98, but it seems like it would theortically fit in a Mex large ring (since the bolt lengths listed in the refernce are the same).

Does this make sense?

Thanks again for the help?

I am trying to put together a 7x57, and I wnated to do so so on a military action with intermeiate length.

David

This goes back to a 1903 Turk bolt being the best candidate. They are relatively cheap still, heck, in fact, the whole rifle will set you back less than what an FN intermediate will cost you. Much easier to find also.

Are you sure your action is an actual 24 Mexican? Does it have the Mexican crest on the receiver ring (an eagle sitting on a cactus with a snake in it's grasp)?

If your measurements are correct, then an 03 Turk bolt might work in your action.

Rojelio

Yes it does have the Mexican crest. It has the typical FN text on the side also.

Thanks again for the help. I'll pick up a 1903 Turk bolt and see how it works.
