Mosin Rebarrel

[jdh47]

Once upon a time Alvin Linden stocked a Mosin for somebody. The picture of it looked pretty nice. I imagine Emil Koshollek did the metalwork.

Getting ready for this years Long Range Match. 6.5x54R Built on a Remington Mosin Nagant. Broughton 5C HV barrel. Got a Silver Medal Last Year with it.

I am always in awe of the ability of the guys on this forum! I have 2 91/30 Mosins with shot out barrels I wish I could rebarrel as well as you guys! Fortunately, I have an M44 with a pristine barrel that shoots the 100s of surplus Russky ammo fantastically. Some day when funds permit I will rebarrel one of the 91/30s with a .308 barrel to make a tribute sniper rifle. Thanks for all the great pictures!

QUITE WEARING OUT THE BBL ON THE 44. buy some lapua brass and try and find some 312/310 match bullets around 150.

Love it. Did you use Manson's print/reamer? Richard's stock?

Just sent this one back to another 07/SOT (he doesn't do riflesmithing).
I get a lot of inquiries to do Obrez conversions- all until now have never come to fruition when I tell them it's an NFA item and get their paperwork straight before sending it to me. Turned off the rear sight dovetail and welded up the pin holes to make it purty. Fitted with one of Nathan's Beast brakes.

I wanted to test fire into my bullet trap just to see the flamethrower but he hadn't sent in his bolt assembly and I didn't have time to headspace one of mine to it. Stock is the one I have for test-firing all rebarrels (no worries about the barrel channel lol), pretty similar to what would have been used for the Obrez but the butt would be whittled down to more like a sawed-off shotty. Didn't ask him, but I'm guessing this is his version of the TC Contender to be fitted with an optic.

That is very cool, Please post more pics when it's done! Is that "Platinum Gray" ?

The reamer was from PTG back when they gave a rat's a@@

The stock is a Richard's Microfit, I don't know why some on here don't like them, I find them to be excellent, They are a lot of work, Which I'm sure you know that. I did the Cerakote in "Cobalt Kinetics Slate Gray"

I true the bolt heads and bush them and turn down the firing pin to match. This is something that has to be done on the 6.5 calibers for sure or they will blow the primers. Here is a pic of the reamer print.

Edit to add: I just realized you also used the new Lo-Profile Rock Solid mount. I wish they had them in canted bases. I am going to put a Spuhr mount on mine so I can get the extra elevation.

Did you read the metallurgical testing and write up that I had performed for @tobnpr

Yes I did, I believe I made 2 or 3 comments on that thread. Very interesting results, Not what I had expected.

The rifle I posted above is the Remington that I bushed the bolt head on and said that bolt was "Harder Than Woodpecker Lips"

The Receiver was also the same and I had to buy a Carbide drill and tap, The HSS stuff would not even make a dimple, I tried to spot anneal it and had no luck. I have spot annealed in the past on Mausers, Springfields etc and had no problems.

I really prefer the WW2 and later actions, Although the old Hex actions are Cooler looking and the workmanship is supreme.

I would like to build a custom on a Mosin action, probably on a chassis.

I think the Peterson brass necked down to 7mm and Ackley Improved would be a great chambering.

Would you foresee any feeding problems from the magazine with the straighter wall case and 40 degree shoulder?

Some have a two piece interrupter , the piece that allows the cartridge ti rise up and feed . The only thing I had to do ( 7.62 x 54 ackley 40* ) was to play with the timing on the interrupter . If I remember correctly, I also had to slightly increase the front mag well .
Take a 308 win and compare the case to the 7.62x54 r . Line up the neck shoulder of each cartridge , some interesting wildcats can be made by using the 7.62x54r reamer and any of the 243.308 class of reamers . It may require some unique machining but after looking at your work I’m sure you can do it .
Pm me in needing some reamers . I may have some old mosin receivers but Ive got many hundred mkore mausers . Much easier and safer

Yes, I have also been wanting to do the 7mm version, If you Ackley or 40 degree it, The mag box will have to be altered as there is a rib at the parent cases's shoulder junction. I had quite a bit of work involved in getting my 30-40 Krag Ackley improved to feed in another Mosin I built. But after lots of work I finally got it. Any cartridge with the shoulder longer than the 7.62x54R will have to have mag and or action mods.

There was a Company in Ukraine that was making some pretty nice Chassis for the Mosin. When the war ramped up they ceased production and export.

On my 7x65R I had to extend the whole mag box 0.550

I would not use Peterson Brass as availability is very spotty, I have been checking for the last year on and off and its always unavailable. I built my .30x54R Improved based on Peterson Brass and I would just stick with Lapua from here on out, It is usually available from one of the normal vendors.

If I was to design a reamer I would base everything from the shoulder forward on what the winners using .284 are using for reamer specs. Please share a print if you decide to do it, Thanks

To Gmac:

The Mosin is plenty strong and can handle many later cartridges as Jackie's Metallurgy tests have confirmed. The Finns built Target and Military sniper rifles in 300 Winchester Magnum using the Mosin as the action.

 

[Sniperhandle]

And to add, I would not worry too much about people whining about you chopping up a Mosin, I chopped a Westinghouse and a Remington, And then sold the remaining parts to the "Relic Worshippers" for a pretty penny. The main reason I did it was because one guy rode me really hard about the first one I did in 2011 so I chopped those 2 up just to get him really going. I would do it again in a heartbeat.

 

[Ggmac]

strength is not onltthe metal used , it is design also . I have no faults with the strength ( within its limits ) just the ease of getting a good rifle . I would much rather have a soft receiver and bolt than one as hard as woodpecker teeth , soft would deform , hard shatters . I’ve was shooting next to a guy shooting a spanish mauser ( hard ) it went boom , he was airlifted out with a bolt in his neck . Mauser is hands down more easily turnedinto a good rifle . Rebarrelling , stocking , selection of triggers , mounting a rigid scope , speedlocking , light firing pin , gas venting etc . I have done a few mosins and have many myself , including 2 bench guns . One in 30-40 krag and one in 30x54r .
The only mosins I would use / build would be the ones with the inner collar like a mauser .
Life gets too short ... too short to test each mosin , the mausers have already been tested . Stay away from spanish , chinese , and some small ring .

 

[Sniperhandle]

I get what you are saying, But to me, Remington 700's
are very boring and I have lost interest in Mauser's, I have done a boatload of them. The Mosin takes a lot of work and attention to detail, I don't mind that it's not easy. I have had some Swedish Mauser's that were just as hard of material, But what a fine action those are.

And to add: Mausers bolts are every bit as hard as that Remington mosin bolt head was, The first Mauser bolt I ever trued up, I tried high speed steel tooling and it laughed at it, Carbide is all that would cut it. I now use a special tool made of carbide to true bolt faces.

That is a pic of the first bolt I ever trued up. I have refined my process now.

I just realized you also used the new Lo-Profile Rock Solid mount. I wish they had them in canted bases.

I "cheat" with the low-pro mounts when I need a down-angle base. I epoxy-bed every mount anyway- so I just set the rear screw a bit high. 20 moa = .035 over 6", I use calipers to measure from the receiver flat to top of rail and lightly begin screwing the rail down (excess epoxy at the front squeezes out) until I've got the down angle I want. I have not had an issue with screws binding because of the slight angle, and this way I can provide any desired down angle within reason from a level scope mount.

I think the Peterson brass necked down to 7mm and Ackley Improved would be a great chambering.

Jackie,
Blasting the Cerakote off the action tonight and shipping to your FFL tomorrow. It's a 1940 Tula with the inner receiver ring. If you're interested in a 7mm- this guy did one years ago- 7mm Altius- PTG has the reamer- print is on the video as well so it can be sent to Manson or JGS.
This action is going to be destroyed, but happy to send you another one for a build anytime, just ask.

Is that "Platinum Gray" ?

Don't know why the pics look like that (?). It's actually Burnt Bronze. I like the look of that with light wood, this is my personal hunting rifle in Burnt Bronze, on an old Fajen stock I scored about 20 years ago.

 

[Sniperhandle]

Very nice tobnpr,

I just realized that you are BigGorilla, I don't know how I did not realize that before. I had thought in my puny little brain that BigGorrilla was out of Oregun and not Fla, My Bad. Are you still making those Bada@@ stocks?


I bet you have hammered some hogs with that!

Gentlemen,
this thread started a fuse in the bck of my brain and when it went off..i remembered..
i have a boyds LEFT HAND mn stock. excess to my needs
the left is a cheek swell on the stock..a cleaver guy could just sand the bump down.
drop me a message..i'll add an ad to make it legit
