A Finnish M28/76

Postby 0933 » Fri Aug 23, 2013 9:33 am

I bought this barrelled receiver from preachere almost a year ago... :roll:

I knew what direction I wanted to take her, and I knew what I wanted to do. I'm finally getting her finished up though! ;)

Here she is.

Image

She is built on a 1900 Tula receiver. She has a 27" long barrel that slugs at .3082" from groove to groove, and .2990" from land to land. The barrel shank is stamped ASEV1 which means this match barrel was torqued on in 1977. There is also 3600 stamped into the barrel shank, which means the Finns proofed her to 3600 bar (52,201 psi).

Image

She has a two stage M27 trigger, which I will keep.

Image

Her cocking peice is modded so that the safety can be engaged with the rear aperture istalled

Image

This is a good thing... With keeping the M27 trigger, I can use the originnal safety even with a base installed.

I was originnaly planning on building my own stock for her.

Image

However, I've been working with Mike to make a modified Viper stock. http://www.biggorillagunworks.com/mosin ... tocks.html The stock will 'hide' the magazine... but will have lines similiar to a Tikka 595. I'll still finish it with a two tone (tan/green) tiger stripe pattern though.

Here is a close-up of the action. I'm going to leave her pretty much as is...

Image

I did however modify the bolt handle. I cut a wedge shaped piece out of the bend, folded it over, and welded the two pieces together. I also ground down the ball and installed a badger ordnance tactical knob.

Image

The overall length, and location of the knob is now very similiar to an RSI bent bolt.

I'm going to install an RSI base on this rifle...

Image

As you can see, the holes are not drilled. This is because I'll be using the existing hole pattern in the receiver. The front hole is far enough forward to be over the barrel threads... and istead of drilling a new hole, I'm going to spin off the barrel, and open up the existing holes.

Once the two holes have been opened up, I'll re-tap them, and then use a mill to drill corresponding holes in the base. I'll install, shim, and boresight before drilling the rear hole. Ultimately I'll bed the base with 20-30 MOA of cant.

I'm planning on shooting 190 grain SMK's, and have purchased a whole new die set with the .308" expander, 200 virgin PPU cases, and 16 lbs of IMR 4350.

I'll keep you guys posted as I get her together!! :thumbup:

0933 your building so many guns lately. Wish I could even keep up with all your work online. This looks awesome. Cant wait to see it done. I am sure it will shout well too. Sounds like the boar is very healthy.

I got to keep the trigger from the job I'm doing. Just like the one pictured above. I put it in my gallery rifle. It's so smooth - I wish all Mosin triggers could be like it. Tomas - did the receiver have a scope mount on it? Was it soldered underneath? I removed the screws and mine would not come off -- I tapped it with a light hammer and the solder came loose.

I bought it without a base or sights... but yes, the base was most certainly soldered on...

here is a pic of the base screw spacing and you can see the remains of solder left on the receiver...

Thanks Jared!! :thumbup:

Here is a picture showing the new bolt handle/knob with an RSI one for comparison.

Image

Here is a pic showing the bolt in the action.

Image

I think the location, sweep, and length will be good... I can't wait for the stock to come in, and I can start putting her together!!

I originally ordered a 10X Falcon mil/mil to go on her... however, I might replace that with a 4-16X Vortex Viper PST.

Before heading BACK to California last month, I machined the two forward mounting holes in the base.

I opened up the existing holes in the front receiver ring, and tapped them 10-32 for the RSI screws. As you can see the forward hole is over the barrel threads.


Image



Here is a stock RSI base for comparison... Mine on the top, and a regular base on the bottom.


Image


I then installed the base and shimmed it until I had quite a bit of positive cant to it. Using some high school trig, and a scientific calculator, I believe I have almost .5 a degree (30 MOA) of a converging angle between the base and the centerline of the bore.


Image


I then drilled the rear hole... marking the center on the left side of the stripper stack.


Image



I then D&Ted the receiver.


Image


Once everything was koshur, I bedded the base with my old standby... JB Weld.


Image



I used kiwi neutral shoe polish for release agent, and using a syringe filled with JB Weld, I filled the gap between the lightening cut in the receiver, and the base.


Image



Everything came out great!! Here is the base...


Image



Here is a picture showing the safety engaged...


Image



Here is the whole thing assembled W/ the bolt. You can see there is a noticable cant to the base.


Image



I've been in contact with Mike over at BigGorillaGunWorks, and my stock should be on the way shortly.

Untill then, I'm going to duracoat the metal O.D. Green...
