Projects

At one time in Canada, there was plenty of surplus mosin nagants and barreled actions available. Now the value of these things has skyrocketed and the utilisation of full military rifles is blasphemous.

NO Full military,Nagants were harmed by me in these particular projects, only harvested from someone elses projects.

It's like the only 28/30 I have was chopped down and painted black under the name "Taiga" as a more marketable iteration back in the 80's. I suspect the work was done in Finland before it got here, but International Firearms, the Canadian equivalent to century arms was selling them out of montreal. It's like the "Finncub" sporters advertised in the 50's and 60's which were cut-down 91s out of Finland.

The first two pictures show how the Valmet 412 scope base goes right onto the identical dovetail under the back sight of Tikkakoski barrels .It also shows how the 5 shot magazine can be streamlined to 3 rounds flush to the stock.

The other 5 pics are a project in an ultra custom adaptation under construction. What is helpful to all Nagant folk is the fact that the 16 thread per inch thread on the Mosin Nagant is pretty much nearly identical to the Winchester model 1895.......and.......the Winchester model 70!

 

[mattimoose]

I picked-up a model 70 take-off barrel in .338win.in a stainless featherweight contour. The guy had 100.00 on it but I got it for 80. Surprisingly, it was so close to the nagant thread that with little to no modification it screwed in.

 

[mattimoose]

I know what you are thinking, and no, I did not make a .338 Win on a Nagant. By removing 7/16" off of the barrel shank, It makes an interesting 54mm long wildcat; effectively a .33 Winchester Improved, based on .45-70 necked-down in .33win. Dies and then fireformed to the 25degree shoulder of the win. Mag. Of course the bolt face has to be opened-up to .45-70 dia.(much easier than any other to open because of the modular nature of the bolt design.)

The magazine had to be widened for the new rim diameter. This sounds worse than it actually is but the key is laying hands on another magazine box.

 

[mattimoose]

You have to be good with a hacksaw; and know a good welder. You hacksaw one magazine from top to bottom along the back of the magazine. Clean up this back face with files or grinder. Cut the 2nd magazine with a hacksaw following either side of the trigger guard. File or grind the excess metal on the inside sides of the magazine box till flush. Insert the trigger guard part into the back of the magazine box front half, making a wider box. Use your action as a welding jig by screwing in the screws front and back and clamp the sides of the box tight until it can be tacked .

 

[mattimoose]

These are pictures of the finished, widened, magazine. In retrospect, it would be more helpful to post the individual steps of manufacture to illustrate the process. I have a couple of extra magazine boxes but I don't plan on doing any more of these conversions at the moment.

 

[mattimoose]

Everyone wants to build a .45-70 on these actions and this magazine conversion with a couple more modifications would do for .45-70, .45-90, or .348 win., .50-70, .50-90 or .50-110, I guess.

In the other pics, there is also a scope base. It is a picatinny adapter for a CZ combination gun I won at the last auction for about 30 bucks. I should be able to cut the same dovetail as the CZ into the top of the octagonal reciever. I have fireformed 40 brass already without sights. Once I get it scoped, it should produce .338-06 ballistics. Case holds 59 grains of 3031.

Not sure how I missed this thread, but thanks for sharing. I love build-along threads.

 

[mattimoose]

These two pics illustrate the thread ubiquity and the useful dovetail. At one time, surplus barreled actions for 91 and 91-30s were available for 15.00

My 1895 Winchester barrel was shot out and was readily replaced with Tikka barrel with like-new bore.

Ok, folks, mad matti at it again. In Switzer's auction- a thing that happens ever couple of months in Bancroft, Ontario, Canada, I successfully bid on a base for a Cz combination gun that set me back all of 30.00. It converts Cz to picatinny.
Anyhow, it's 13mm dovetail and short attachment length made it absolutely perfect for my octagonal receivered Nagant project. The flat on the reciever was a little over half-inch-13mm. Wide. I set-it up in the mill and the rest is history.

 

[mattimoose]

Not the best picks, but after roughing -in the deck with a 1/2 inch end mill to about .530, .080 deep. I then used the 60 degree cutter to bring the dovetail together to about .516 or 13mm at the top. The Female dovetail base is about .080 or 2mm deep. I made the cuts in the male dovetail to .085 depth.

I intend to put a Leupold 1.5-5x20 on this rifle but did a mock-up with this bushnell I had at hand.

What you are looking at is a prototype, quick detachable scope mount for a Norwegian Krag Jorgensen. I mean to weld it to the side plate(I have extra side plates)
