About a year ago, I bought a Mosin Nagant and an ATI sporter stock to practice bedding; something I had not done before. If it went wrong, I wouldn't have destroyed a really nice rifle, right? :D For $150 + $100 it was about as cheap as I was gonna get it.

I took the rifle out in stock configuration and hated it. My groups at 50 yards were about 12" using iron sights and my own handloads. The length of pull was way too short. The trigger was rough and crunchy. It could only get better from there! After returning home, I did some inletting and floated the barrel using a dremel and sanding bit. The action was bedded using epoxy steel and everything went well. All the info on how to do it came from various online tutorials and videos.

The next day, I went back to the range and, with the same load recipes, shot groups half the size! I wondered just how well I could make the gun shoot and so a project was born.

A little about me: I'm not an expert marksman and am not a gunsmith, just a guy who really likes shooting and keeps looking for ways to improve my shooting. I learned a lot about accuracy from this rifle, about technical processes and reloading, bullet selection, bedding and of course, shooting technique.

I ordered a Bushnell 2-6x32 LER scope and Darrell's scout mount which is as reviews said: rock solid. It has not budged since being installed. I also ordered a Huber Concepts adjustable trigger and it made a world of difference. All in I spent about $540, rifle & stock included. Then, I sold the wood stock for $70 so net net it worked out to $470. The next step was to work up accurate loads and see just how small those groups would go.

Here's the rifle. Sorry to all milsurp purists. This type of modification is usually met with hostility from the milsurp crowd.

Here's the shooting setup: nothing special! The helmet bag has a towel in it. Most shooting was done at 50 yards, occasionally at 100.

Finally, today, I got down to less than 1" (at 50 yards). This doesn't sound particularly impressive, but to go from 12" to 0.448" on such a cheap gun and to have as much fun shooting it as I did is worth sharing!

Bullets Used (all .308)
Hornady 150gr FMJ BT
Hornady 110gr FMJ
Hornady 110gr VMAX
Hornady 165gr BTHP Match
Nosler Partition 150gr
Nosler BT 150gr
Sierra 168gr HPBT
Speer 165gr BTSP Match
* All the BT and match bullets were accurate, the best being the Sierra. I tried lots of different combinations of powder & bullets...too many to list.

Powders Used
Varget
H4895
IMR3031
Win748
BL-C(2)

Brass is PRVI all from the same lot and only WLR primers were used.
 
Way to go and well done. These are some of the projects I have enjoyed the most.

Something to consider, the bores on these rifles were usually larger then 308 despite their 7.62 nomenclenture.

In general, they shared the same bore as the Lee enfields which range from 310 to 312

Since you found the Sierra shooting the best, measure the diameter. Odds are it is one of the widest bullets.

If this is true, you may find 311 bullets to shrink groups even more. There are lots of options in the 310 to 312 diameter so let me know if you want to try some.

Also, get or make up a target that fits your reticle crosshair. Shooting into a circle is not easy to keep same POI.

Let me know and enjoy...

Thanks for sharing, especially your load info. The more accurate Mosins were used as a sniper rifle by the Soviets, Warsaw Pact forces, Chinese, NVA and Finns. Milsurp collectors (and I'm one of them) only get really upset if you bubba something rare like a M91 Cossack or Dragoon rifle, etc.

It's your gun isn't it? Purists are just that, purists
Good on ya to go your own way


This is as far as I've seen someone go with a milsurp, can't remember his CGN handle though
 
Seeing that made me want to gouge my eyes out.

That is a great post! I have to admit, I was rolling my eyes when i read the title, but I am very impressed. I too was going to chime in and tell you that going to .311 bullets would probably tighten things up They are spec'd (If Soviet tolerances count for much) for a bullet of .312".

Keep up the good work and thanks for sharing...

I laughed at the LE, but whatever floats your boat!
 
I have one of Darrel's scout mounts on my M91/30 Tula ex sniper with an NC Star LER . It was certainly cheaper than buying the repro PU scope setup.
 
That is a great post!

Thank you :D I know it's goofy, but there are a couple of reasons for it:
- I'm left handed. Since the bolt rests at 3 o'clock, I can operate it easily without a scope getting in the way. I was thinking I might hunt with it one day and wanted to keep that option open.
- No drilling & tapping. It's just a bolt-on mount.

Ok Jerry, PM inbound. Sell me some bullets...and maybe a .311 neck sizer as well!
 
Good on you. The quest for accuracy has to start somewhere. Everyone finds where they want to go with it and the end justifies the means. Not everyone wants to shoot 1,000yds and most of us are not rich. I always enjoy the beginning of projects and where they end up. You always learn a great deal which in turn kindles more ideals.

Being a southpaw is not a disadvantage anymore. So many LH rifles for sale on the EE!
 
You inspired me! I have the same rifle and stock and it seems the rifle shot a bit better with the old wood furniture on it then it did with the ATI. So after reading your thread I thought why the hell not. So I got some JB weld and bedded the action saturday night. I know JB is probably not the best stuff to use but what the hey. So it's too cold to head to the range now but maybe this week i'll give it a shot.
 

Let's see:

- Battle proven repeater action that was considered one of the fastest for cycling.
- 10rds detachable mag
- Magpul Sniper buttstock and contemporary grip (HK style)
- "composite" forend.
- oversized tactical bolt knob.
- ACCURATE 30cal chambering that matches 7.62 NATO specs
- Easily tuned trigger for a single stage 2.5lbs pull
- Dead reliable safety

Swap in a FFP scope with honking big knobs and a different bipod, what's the diff to the many other rifles of similar build - besides the cost?

I believe the Brits used the Lee as the basis for their sniper rifles and was plenty successful for many years. Eventually leading to the AI's.

Having played with Lee No4's, I know they work. They will not play in the magnum pressure ranges but that isn't needed to match NATO specs.

Wouldn't surprise me if this rig shot 1/2 min or Better depending on the barrel.

Nice stuff....

Yeah, I wonder how good I can get my 91/30 shooting if it was doing 4" with irons at 100 right off the bat, the first time I shot it.

So I took Jerry up on this and have had positive results using .311" PRVI 150gr FMJ BT. The best so far is 0.397" (still at 50 yards). The rifle seems to like the bullets seated out past 2.950" with the groups consistently better than below 2.9". I have only worked up 3 loads so far, all using H4895. A good start!

I guess my targets are a little Mickey Mouse eh? What would you recommend? This is what I'm looking through:

Have you slugged your bore yet?

You could be working with a .312 or .313's bore without knowing it yet.

I use .312 Hornady 150's backed up with H4895 and that combo works very well in my Nagant.

Not bad for a stock Nagant from 1942. That's at 100m w/ Irons. Nevermind the flyer's. :redface:

Good luck with the quest!
