I have a mosin nagant I recently took to the range and I had trouble chambering a number of rounds. I was able to shoot 5 or 6 than I had a number of issues chambering a round. I was able to drop the round out and than attempt to chamber it. This worked sometimes and sometimes it did not. What seemed to be happening is the round would be forward of the extractor and for some reason it would not be able to completely close the bolt. I at first thought maybe my resizing die was not set correctly, but I had some Unfired Prvi shells that I experienced the same issues with. Anyone have any idea what could be causing my issue?

Mosins are supposed to work that way - it's a push feed bolt design. The extractor snaps on the rim only when the bolt is forced in the forward position. Check your extractor for free movement and for burs, especially look for burrs on the extractor face.

I checked the extractor and it did have some minor buildup but I didn't see any burs. I cleaned it really well and I am going to use 600 grit sand paper to polish it really well. I will let you know if it helps. Anyone else have any other ideas as to the cause, just in case it is not the extractor?

Your COAL set right? You sure you resized properly? etc.
COL should be fine.
The privi shells are 3.008 inches long - these shells are the ones that have the worst issue Chambering
My handloads are 2.846 inches long
And Horandy manual list max length at 3.048 inches.
Could the gun have a shorter throat/chamber to cause the issue?
Any other ideas?

Even if the round can not be fully chambered, the extractor will grip the rim.

If the serial numbers don't completely match or you have a force match (last 3 numbers match) quite often the bolt makes to much contact with the receiver. I don't know all names of the parts - so bear with me. The piece of the bolt where the serial numbers is located is to long. It looks like it's helping to extract but the gun doesn't need help until the last inch or less. I have seen a lot of Mosin-Nagants with that problem. The only other problem I see in almost all mosins is they shoot high. thats another thread....

Make sure you have clearance between the stock and the interruptor/ejector on the left side of the receiver, or you can get all sorts of rimlock and bolt binding taking place.

Make sure you have all the cosmoline out of the gun, out of the chamber, out of the bolt and out of the trigger. Boil the bolt and use a brush in a drill with mineral spirits on the chamber.

sounds to me like it could be the "sticky bolt" issue... i had this issue when i first got my mosin.. after shooting a few rounds for the life of me i couldnt get anything to chamber anymore... so... i took the bolt out of the rifle, disassembled the bolt completely, washed every nook and cranny with dish soap and hot water, then dried, re-oiled, and reassembled and never had a problem since
since the unfired shells did it to, it would lead me to believe this could be the issue... years of being soaked in cosmoline do this

dont use a brush on a drill for anything.... ask me how I know
Use a mop, with a very light polishing compound if you want to be aggressive.
I use non-chlorine brake cleaner and then oil well....

all i used was plain ol dish soap.. cleaned off the springs with it too... to clean out the inside where the firing pin goes... i think i took a piece of paper towel and rolled it up into a long cord and ran it through a few times... got all cosmoline off the bolt
another thing you can do, is simply boil it with some dish soap and thatll clean out every bit of cosmoline, just remember to get it completely dry, and apply new lubrication so it wont rust
since then, not once have i had anything get stuck, its been smooth and clean ever since (for about 3 years now)

Thanks for all the input guys - I am in the middle of a move so I will most likely not be able to
1. Disassemble and clean te bolt thoroughly.
2. Make sure the action fits the stock.
Anyone know of a good substance to put on the action so I can see where it is making contact with the stock, so I know where to sand?
Thanks again everyone!

I've used lipstick before for stuff like that. Shows up easily and cleans up quickly. Just don't let your SO catch you using their favorite color.

Morcey2 - lipstick worked great! I took some more material out of the stock and disassembled and cleaned the bolt. I also put some kroil oil on it and worked it a few times with some dummy inert rounds I made up. It is smoother and the chambering problem seems to be gone. I will play with it a little more before I get to take it to the range just to make sure it will be reliable.

i still have the military stock on mine.. mosin nagants arent all that accurate for bolt actions, id consider 2MOA to be accurate for them with military barrels so i didnt see a reason to scrap my stock
