Having issue opening mosin bolt

[Stormtrooperthunder]

When I first got the mosin it had no issues at all. Functioned fine and everything.

Now I have issues opening the bolt when I have been dry firing. I used the decocking feature a few times and it seems like after that I need to pull back on the cocking piece to open the bolt. I seems like it does not want to open most of the time.

I have not been firing lacquer cased ammo, I was using WWII reworked ammo from SGAMMO. I did take the bolt apart, so maybe I put it together incorrectly.

Is there something I can do to remedy the problem?

I will try to make a video or something later

The bolt chamber would very likely be the issue. Go to you tube and you will find out how to resolve it. Its very easy.

The Mosin bolt is generally pretty tough to cycle. The handle is short so you don't get much leverage. Make sure it is clear of all cosmoline which should help.

Maybe you did put it back incorrectly. It doesn't hurt to double-check.

About hard turning bolt:

A little tune up of the bolt body and cocking piece is all it needs.

If you look on the top of the cocking ramp/cocking piece you'll see a little ridge, if you look on the bolt body you will see a corresponding V groove in the bolt body that the cocking piece sits in in the cocked/open position.

If you stone down the top of the V in the cocking piece and touch up smooth the edge's of the V groove in the Bolt body you will have a much smoother break/closure during the initial turning down of the bolt.

Another area to look at is for Chamber burrs in the 2:00 o’clock to 5:00 o'clock from the extractor rubbing against the chamber end (closing bolt on empty chamber) and rolling a burr into the chamber, check for scrapes in that area from extraction, if you have them you will need to deburr and or polish chamber edges.

You do not need to cut any coils off of the firing pin spring to get a smoother less effort bolt lift to load the Moison 91 rifle.
The Moison 91/30 and all its variants already have a very slow lock-time due too the heavy mass of metal/parts (cocking piece) attached to the firing pin and spring, removing firing pin coils only slows down the lock time more and may cause misfires (light striker hits) in cold weather.

If it also closes hard, try to loosen the trigger guard screws a little. I had a Mosin that needed the trigger guard shimmed down from the receiver. It would close very hard, not sure about opening.
I could see this being the case if the loaded magazine pushes the trigger guard down but your 5th round would be difficult to chamber.

just an idea.
