So this is the second time it has happened to me.

I load my Mosin up, fire some rounds no problem.

Maybe 40 rounds down range I pull the bolt open, next round goes in, and just when the bolt closes all the way, BAM!

I am far from being an experienced GS so I have no idea what could be causing the issue. I do know however that my trigger is STUPID light. I mean, I could practically blow on it and it will shoot. I have a feeling that because of this, when I close the bolt, the jerk causes it to fire.

First time this happened I changed the "back" part of the bolt with a spare I had and it seemed to work for about 100 rounds. I have a bent bolt but I don't think that's causing the issue.

Anyone have similar experience or any input?

Hmm? Is your firing pin adjusted correctly?

When a bolt action rifle does this you don't have enough "sear engagement". First make sure that everything is clean and then make sure that the trigger spring has enough "oomph" to fully engage the sear.

This is common on a lot of rifles where people have stoned off the sear to reduce creep and cut springs to decrease pull weight.

Hmm.. I've never played with the trigger... It could really be anyone of these issues... Anyway to determine if my firing pin is too long or if my trigger is messed?

Ruso,
When I bought my first M44 the trigger was a lot like how you are describing. I took it apart and it was a simple screw loose. (In the trigger spring, not in me.)

I tightened up that single screw and voila, back to my long heavy trigger pull that I am accustomed to in my Mosins.

My trigger actually flopped a bit, so if yours is not loose, probably not the same thing.

Also, if you don't have the Mosin tool as shown in the video I can bring one up to Centralia, Olympia, Lacey area on Saturday.

I bought the sets from Big5 so I think I have one laying around somewhere. Hmm goo to know I will have to take that son of a bitch apart and take a look. I guess I may as well seeing as how I plan on transplanting him into the ArchAngel stock.

Just as a side note, this is a great example of why all of us should keep a rifle pointed down range when closing the action ... even if it's "just" a bolt-action rifle.

Yes, at Renton when activing the bolt or slide the rifle needs to be pointed on target (berm) downrange.

Good reminder...

I never let my muzzle cross anything I'm not willing to destroy, so when I found out this issue exists the rifle was down range without any potential of harm

Good to hear. Sorry, I wasn't directly my comment at you; I was just using your rifle as a reminder to the rest of us.

Most folks recognize that semi-auto rifles can slam-fire and are conscious of muzzle direction when chambering a round . . . but often we think of bolt-action rifles as 'safe' when chambering a round. Obviously that's not always true.

Update.

Took the rifle out of it's current Monte Carlo. Stripped it down completely.

The screw that holds the sear with the trigger was NOT loose.
Checked the firing pin depth and it was where it needs to be.

Put it back together, same issue. As soon as I close the bolt, *click*.

Took EVERYTHING apart again.

Noticed that on the trigger (not the spring with the sear) there is a lot of scuffing on it. Not sure if this is causing the issue or not though.

I think I am going to just purchase a brand new trigger replacement. "new" trigger, sear, screw etc. Hopefully replacing that will be all it takes.

I ordered a Finnish sear spring/bolt stop. Did a lot of reading and these have excellent reviews. Along with that ordered up a slack spring.

$25 shipped should hopefully be the solution I need.

For now, my mosin is just a pile of neatly organized parts. I'm going to clean the hell out of everything, lube it up in the right places.

Once it's operating properly, off to TA for a nice CeraKote finish and into the ArchAngel

*ahem* Some of us like firearm porn.
A neatly organized pile is better than nothing.
Updates with photos get more points for redemption later.

Only fair.

Here is the parts that make up my mosin.


Here is the sear/trigger spring that I think is the cause of my problems.



Here is the actual trigger that may potentially be an issue. Any gentlemen want to chime in?
