Mosin Kaboom

[NaughtyMonkey]

Ok thanks Datamancer. One of my mosins is having that Stick Bolt Syndrome so I want to clean the inside of the bolt and hopefully that will help it out.

This.

Could be a weak sear, too. I've got an M44 with a very weak sear that I don't won't shoot. If you slam the bolt forward it will release the striker every time. If you are gentle with the bolt, it'll hold ... most of the time. Haven't gotten around to replacing the sear yet.

^^^I had a mosin like this. HOWEVER, it was because I was a dumb kid (my dad bought the rifle for me) and my original bolt was VERY hard to operate, so I went back to big 5 and swapped the bolt with another Mosin from another country IIRC.

The trigger pull was much lighter and the bolt operated quite smoothly but it fricken "let go" as I was closing the bolt and it fired. Good thing my dad returned the rifle!

...and here i was berating myself for not holding out to get a hex mosin. meanwhile, my 91/30 has endured hundreds of rounds without trouble. nah, just kidding, i'm glad to hear everybody with these tales lived to tell. this is why i don't care about special models/years/markings/etc....because i may not have the most elite or pretty rifles, but they all work and none has blown up on me so far. keep in mind i have shot my own handloads in a good portion of these rifles as well. whenever i add a new one to the paddock, i tie it to a tire and pull the trigger with a string for the first 5-10 rds. this is a good way not to frag yourself with an unknown, explosive rifle. just my $.02

A while back at a gun show I saw a beautiful M91 "Westinghouse" for only $180. It took me about a minute to find a crack going down the right side of the chamber. Very sad but it can and dose happen.

Saw a picture awhile back of a Swedish 1896 mauser with a failed receiver. It can happen with any surplus rifle considering how many were made and the service they have seen over the decades.

Newbie looking for a Mosin/nagant

Glad to hear no one was hurt bad.

I am currently looking for a mosin/nagant.
I was wondering if the hex receiver is the strongest.
I am looking for the same rifle, but now I am nervous.
I was going to buy 2, one for me and one for my 14 year old, to have competitions.
Any reply would be helpful.

WOW cracked in half! I would never think of that happening!

There's no real difference in receiver strength of round vs. hex. Out of the millions of mosins built, I've seen a grand total of two failed receivers, and on one the guy was intentionally trying to blow it up. The chances of a receiver failure are very, very small. I would't worry about it as long as there are no cracks.

It is, more meat than a round receiver, and they were not made in a hurry during war years.
That one had other issues, it was one out of millions made, and even though it broke completely in half, it still didn't grenade......that tells you something.

[SoCal Bob]

Tsopka, there are millions of Mosins out there and only a handful of problems reported. From what I have read there is no significant difference between a hex and round receiver. What you want to do is make sure the serial number stamped into the bolt matches the receiver. Headspace should not be an issue if they match.

You do want to do LOTS of research on the Mosin to see how to clean off the cosmoline and how to disassemble the bolt to remove cosmoline and then to make sure the firing pin height is adjusted correctly. Youtube is your friend.

I also recommend picking up a recoil pad. Walmart sells a Winchester limbsaver (size small) for about $20, money well spent.

Good luck and enjoy, they are addictive fun, I have 3 - 91/30's an M38, 3 - M44's and should be picking up 2 - M39's this week.

Newbie looking for a Mosin/nagant

I appreciate the input, I have decided to continue looking.
I am going to continue looking for a hex receiver ex sniper, 2 of them.
The recoil pad is a great idea, did not think of it.
Thanks again you guys are great!

[G-Man WC]

Wow, Now we all understand why eye protection is mandatory on the firing line.
Glad things turned out with everyone safe. -g

I am scratching my head on this.

I went to the guys blog and checked out the pictures. I will admit at first I didn't recognize the differences from the old crack and new crack until someone mentioned there was an old crack plus how you could see the new crack.

The way the receiver cracked, was there no way, to find a crack like that visually? I know that the crack had bluing in it, but shouldn't that in itself made some sort of deformed marking on the receiver?

I am not a metallurgist or a machine shop person sorry for the newb questions on metallurgy.

Take a look at the last photo. There's a substantial crack in the stock right below the broken piece. That barrel may have been flexing in there for some time.

Yeah the bright, shiny part of the crack is the new damage. The rest of the crack shows dark surface tarnish which has obviously been there a while.

There's a very good chance that the crack was visible from the outside, especially because the outer edges of the crack would have started to pit like the rest of the dark portion of the crack. The owner probably just didn't inspect it very well.

I chalk this one up to Operator Error.
