What to do with a lost M39 M. Nagant ??

[Clark]

Over the last 15 years, I have rebarreled the Nagant action to 45/70 single shot, 223 single shot, 30-30 single shot, 7.62x54R repeater, 7mmRemMag repeater, and 300 WinMag repeater.

Over the last 52 years, I have sporterized Mausers.

None of this work is cost effective. You have to want to do it for hobby sake.

I got my 1915 Westinghouse / Sako M39 for $90 in 2004. It is just some old military gun, and means nothing as a collector to me.

Right now I am working on a Colt 1849 made in 1859. I am trying to keep it as stock as I can.

plenty of collectors do not care about bore condition. id not mess with the gun.

Plug the chamber,put a piece of plastic tubing around the muzzle for protection against spillage and fill the bore with Evaporust.Let it set for a couple of days.Drain and clean bore.It may shoot OK.

will that harm the blueing, if some leaked out?

what about same idea with vinegar?

I would shoot the rifle first. A lot of folks can't get their head around the fact that rifle with dark bores can be accurate. The M39 is also unique in that the bore diameter is designed for the .308 diameter bullet but the .311 diameter can be used in a pinch if need be. If the pitting is not too deep a little polishing may not be bad if you are shooting .311 diameter Russian Ammunition from your rifle. Just a thought.

The Evaporust will remove the finish.That is the reason foe the tubing over the end of the barrel.The same method as was done in the Army when removing metal fouling with 28% ammonia solution.If the bore doesn't have an extreme rust build up you can just shoot it as suggested.It may still be accurate.

Post #17 suggests it shoots good. Post #1 says it's ruined. Did you put it up dirty after firing corrosive ammo? Like millions of people do every day? I'd say follow the above cleaning advice and see what you've got. I had a 1927 Finn/Sako that shot great- but it was still a clunky Mosin so down the road it went. Your gun will probably be fine after cleaning the crud out. I've had ugly bores that shot fine like others have mentioned.
Clark- the belted mag conversions sound interesting! Start a thread, maybe?

[bob208]

as stated most of the finn. m39s were rebuilds anyway. I would rebarrel it with a good military barrel.

sad thing is most of the military rifles with rusted bores. got that way from people firing cheap surplus ammo and not cleaning them. not from military use.

[largom]

I would clean the bore good, then shoot 10-12 fire-lap boolits , then see how it shoots on target.

The rebarrel threads and extractor relief are straightforward. The feed lips mod is a little harder, but there is info on line.

My trick is the 3.34" OAL will not eject unfired. The ejection port is a cam surface front and rear and cannot be opened.
So I put an ejector override button that is spring loaded with the ejector acting as the spring.

Here is a mosin repeater in 300 Win mag Krieger barrel with 125 gr NBT taking a 3x3 buck.

Very neat, Clark! Obviously the Mosin is a strong action- for a farm implement lol.
Just kidding Mosin devotees!!

this would be the most i would do. if you chose to rebarrel, your out the price of the barrel, the gunsmith work, and you've turned a $350-400 rifle into a $200 rifle tops.

The Actual Value of the rifle only matters if you intend on selling it.

^^^this! If it won't shoot, sell it to the collector who doesn't care!

Contact John Taylor/Taylor Machine for a reline of the bore. You will still have a 7.62x54 rifle with a mint bore and perfect chamber. Cost way less than rebarrel and leaves the markings intact.

I would doubt if it is much less. But if I wanted this rifle restored as a shooter, I think lining to 7.62x54R would be most satisfying, and do less harm to value than anything else. Track of the Wolf sell a liner made by TJ's, meant for the .30 Luger, which should have an excellent groove diameter and twist for this rifle or the .303.

That liner is ½" diameter, which I think wouldn't allow chambering in the liner itself, without a risk of swelling the chamber. The usual procedure is to silver solder a piece of larger diameter tube to the rear end of the liner. A technique I will try when I find the necessary round tuit is to pull the cutter through the bore, which I believe can produce accurate enough alignment with the existing chamber, the join being covered by brass. Yes, I will try that when I get a round tuit...

Rotabroach cutters are worth looking at. One of those, amputated where it is still fluted, will give perfect clearance for the chips, and can be piloted on the pull rod or a bushing.

You'll probably find that pits that look a mile deep are actually only a few tenths of a thousandth deep.
It takes a great many years of neglect for a bore to become deeply pitted. A couple of years uncleaned in a closet won't do irreparable damage.

Ordinary neglect, such as a rifle left unfouled and with bore unoiled, yes. But I think that is a lot less likely with neglect after firing corrosive ammunition.

[charles1990]

Step 1. Clean it very well.
Step 2. Buy a fire lapping kit and do it.
Step 3. Shoot it with good ammo.

If a guy with young eyes can put 5 in 3" @100 you're good to go.

If not, you have to decide what to do.

Many good suggestions but ----- it is your gun.

I had a pristeen (outside) 1903 Springfield in 30-03 made in 1904 that I bought at a VFW post closing auction. The bore was a black hole, beyond anything to salvage it. (Corrosive blanks)

A collector snapped it up for $2000 ---- that was 10 years ago. Good luck finding one today !

Clean it as best as you can. Shoot it and see what kind of acceptable (to you) accuracy you can squeeze out of it with the present bore condition.
If you can live with that degree of accuracy,,and not wince at the condition of the less than perfect bore everytime you look down it,,then keep the rifle.

If you are like a lot of folks that just can't stand anything less than a perfect mirror bore,,then sell the rifle as-is,,take the $$ and buy a better conditioned piece.
You will be farther ahead in both money, time and frustration.


If you keep it ,,some fix'it options,,
Re-bbl??,,McGowen currently makes a 'pre-fit' for the M/N. It still needs the extractor groove cut and you'll need to final fit the bbl itself to the action. Not a kitchen table project, $300 to start,,,maybe you need a different contour? that's extra. Plus the labor out of pocket expenses to get the bbl fit up, old bbl off, ect..
http://mcgowenbarrel.com/mosin-nagant/

Another re-bbl possibility is to contact 'dpcd' over on the Accurate Reloading Forum.
Usually can be found in the Gunsmithing Section but posts in most any of the sub-forums.
http://forums.accuratereloading.com/.../frm/f/9411043
He does a lot of re=bbl'g work, makes and sells pre-fit bbls of specific contours for classic rifles and is a great all around gunsmith.
He's made up and sold several M/N sporters on that forum in various calibers
Contact him and see if he may have a bbl available to suit your needs or if he can make you something.

Rebore/Rerifle..that'll run $250+ at the current cheapest rates around and you won't have a 7.62 anymore but will have the orig tube.
I also heard JES doesn't like to cut MilSurp bbls anymore, but call him and ask.

Re-Line,,it's going to be tough to find someone to do a re-line on a high pressure rifle cartridge. One way was the 'slug' method as described already but w/o using a separate liner and extra large dia tube at the breech. A one piece liner with that characteristic was turned from a bbl. The old bbl reamed to fit and the whole assembly put together. Even then the practice was questioned depending on who you talked with. The cartridge involved makes a lot of difference too. Won't be cheap either with the work involved no matter which way it's done. A chamber reamer rental or buy is involved.
A guy like John Taylor would be someone to ask about such a reline project possibility,

Just some thoughts..

The M39 is a nice rifle,,wish I had held on to the two I had.

[Ballistics in Scotland]

I don't think it is that hard to find someone who will install a liner tube in a fairly high pressure centrefire rifle. The tooling for that deep drilling and reaming job is expensive. For someone specialist enough to have it, it isn't too difficult a job. But for the general gunsmith it isn't worth buying it for what might be the only lining job of that diameter they will ever see.

[2152hq]

It isn't about having the tooling, or not,, or the abilitys,,it's usually the idea itself and wether it's safe to do with some cartridges and their high(er) working pressures.
