Hi folks,

a friend of my son brought his grandfather's gun - a sporterized M10. It's been sitting in a cupboard for many years. There's an issue with it, and I'm a bit (or a lot) clueless with Rosses. This kid got his PAL and he hopes to be able to try this rifle - especially after I've explained Ross' place in our Canadian history.

From what I understand, the bolt head, somehow, has rotated 90 degrees and thus, I can't either push the bolt in all the way, nor remove it from the action. Anyone ever encountered this issue, or has any idea how to resolve this issue? Thanks in advance for any insight,

Lou

Hi Lou,
I am sure you have seen the sticky about Ross bolt dis-assembly in this forum. I don't know if it will help much.
Another source of info might be on the Ross Rife Forum. There are some very knowledgeable folks there and a few CGN members as well..
If I recall, Smellie knows a bunch about Ross rifles as well. Maybe a PM in his direction would help you out.
 
Strangely enough I think that my son's first Ross arrived somewhat like this. Sadly I disremember what it took to get it rectified...other than holding your tongue just right
In hindsight it wasn't hard...maybe...?
Good luck
 
Lou

Is the bolt in the two rails at the top rear of receiver?

Try removing front action screw of floor plate and push magazine away from bolt, if possible.
I take it that there is no access to tang screw?
Pull Trigger as you pull bolt back with the bolt lock open as you have in the picture.
Will likely have to jiggle the bolt as bolt head goes tube part of rear receiver.

I took a look at one of my Ross MkIII (M10) actions.
It looks like the rifle you are working on has had the charger bridge removed and then the bolt inserted incorrectly. The pictures in the Ross bolt disassembly sticky are great and they will give you some idea of what things should look like if properly assembled. Those locking lugs should be parallel to the rails that the bolt slides on and they should be above the rails. The bolt head should be extended about an inch out from the main bolt body.With the bolt in its current position with the lugs perpendicular to the rails, there is no way I can see to turn them into the proper position.


Good luck

Looked again and Diopters post above may hold some promise.
I would remove the stock. The rear action screw actually holds the rear of the floor plate to the assembly anyway. So, 2 screws to undo, then once the floor plate is off the action can be removed from the stock. Pull the magazine off and then have a closer look at the trigger assembly. There is just one pin holding it in place. With the mag and the trigger assembly out of the way you may have room to wiggle the bolt out.
Somewhere I have a pdf of Ross MKIII manual with complete disassembly instructions. PM me if you would like a copy.

There seems to be a bit larger portion in the rails closer to the receiver ring, my recommendation would be to try and turn the bolt head at that larger portion. It will likely be a pain, and will likely take a significant amount of effort and swearing to get done.
 
Do not pull the trigger as it has a lever that comes up to lock the bolt when pulled.

You may be able to partially disassemble from the back as said above. But I don`t think you will be able to separate the bolt head from the body with out turning it.
It may pull apart a bit though.

I would try driving it back with pressure from the front on the bolt head.
Either angled with a dowel or though the barrel some how.

Be careful of the firing pin and I do not think beating too hard on the bolt handle is a good idea.

I've disassembled one like that. Took some jiggering and a bit of force, but unfortunately I forget exactly how I did it.
The stock cannot be removed, because the bolt covers the rear tang screw.
As diopter suggested, remove the front screw, see if you can loosen the magazine. The mag. has a rear flange that the bottom locking lugs will contact. If I remember correctly, that might block the bolt, and will get bent.
If you need to use force, just place a block of wood against the bolt handle, and tap that with the hammer.
The bolt got pushed into the receiver with the lugs like that, so there has to be a way to get it out.
 
I've seen this problem successfully addressed in an earlier thread. It was probably within the last year and was most likely on the Ross website or the Milsurps website. MKIIIs can be a pain when installing the bolt. The bolthead has a tendency to snap into the closed or battery position before the rails engage. That may be what has happened here and it just might be the key to disassembly. You might be able to move and rotate the bolthead forward while moving the bolt body to the rear. If you can gain enough space to clear the rails, you may be home free - especially since the bridge has been removed. I don't think you will be able to move or remove the magazine without completely removing the trigger guard.

I will try to find the thread.
 
I've had this happen - in the field no less. There is a catch under the bolt that needs to be released with a small screw driver, should be able to pull the bolt rearward then.

The pawl in the front of the trigger mechanism? I can see that snagging the lugs.
Get the bolt open as far as possible, and then use a small screwdriver or probe?
 
Be careful whatever you do Lou. A member here parted out an otherwise perfect MkIII recently because the former owner dealt with this exact problem with too much force. You will get it back out, it will just take patience. When you do get it back, fiddle with that bolt and see if the bolt head will go into the unsafe condition assembled and if you can return it to proper orientation while still assembled. I have an M-10 (280 sporter) here that will do that. If this one will the young owner needs to know how to properly deal with it as it can be deadly if not rectified.
 
Just experimented with a spare receiver and a bolt. The lugs are probably catching on the ejector. Just use a probe to press the ejector away from the lugs to release them.
The sear and roller will also be putting pressure on the bolt, but it should pull out past these.
 
Victory!

Thanks everyone for your very helpful comments. It was a bit complicated but in the end, the bolt came out.

Now that I can observe the two parts seperately, the first thing that I notice is the rear of the magazine well. I will wildly let myself to propose that this part shouldn't look all buggered up like this?

Got the mag well out. And, going even more onto slipery ice, I'll suggest that the magazine box, once removed, allows me to see some damage which will require some repair?

Anyone can send me a picture of what this should look like if it was in good shape? I probably will have to weld and shape some sheet metal...
