So I get this 1943 dated M91/30 in pretty much MINT conditon(probably refurbed)...perfect wood/perfect metal/gleaming bore

It shoots 12-15" groups.

really....this is with the yellow tipped Hungarian heavy ball.

What does one look for when a excellent condition gun shoots like a slingshot?
How can this thing be 'accurized' without screwing around with bedding or crap like that?

This is pretty important as I intended to mount a '41 dated PU scope on this thing and make myself a 'Zaitsev' rifle. But if it wont shoot it aint gonna happen

Barring all that....anyone want to trade a excellent 91/30 for one that shoots?
 
Have you slugged the bore? Some of the war produced rifles had very over size bores even when new. 12' does sound like a bit much though, try another type of ammo.
 
I use the czech stuff in my 1891/30 and I can get 4-5" groups.

Sounds like something is wobbling on you...got a loose band?

I had a scout sporter with a red dot that I could get 2-3" groups no problem with the czech. The barrel on that one was free floated.

I'd check and see if the stock is loose or bad fit. Maybe bed it or tighten it up.
 
Could be a loose nut behind the wheel.................


I would say you need a little square shim under the barrel. I have that finn capture magant that has two little shimms which keep the gun from wobbeling inside the stock.

:rolleyes: Smart Azz

I tried putting a brass shim in exactly that spot...apparently the Finns know more about that than I

So how do these stocks work?

Should the wood 'clamp' the barrel for the full length?
Or should there be no contact beyond the reciever?

Im not about to switch ammo....I have 2 crates of the Hung heavy ball and it shoots great out of all my other rifles.

What was done to the true Nagant snipers?...I thought they were simply stock rifles that happened to shoot good so they got scoped

I don't care who you are, that's some funny #### right there.
 
As far as i know, no contact other than at the reciever. The original snipers were stock other than the scope mount & sight in (Some had shims). Never seen one shoot that bad though & I have some pretty boreless wonders. They don't seem to care too much about bore condition, just gets harder to clean( in my case). Really long throat maybe?
 
First of all, check the muzzle wear and crown for burrs. You might need to recrown the bbl. Next, I'd look for bedding problems. Maybe apy some graphite to the receiver, assemble and dis-assemble then look for high-points in the bedding.

Lastly, tighten all screws good and then see if you can moe the receiver around in the stock. Want to make sure everything is snug and doesn;t move around.

I assume you;ve checked to make sure the dovetail is tightly peened on the front sight and that it's not shooting loose?
 
Everything is tight/excellent condition on this gun

BUT!!

The stock at the muzzle end contacts the barrel
The handgaurd at the muzzle end ontacts the barrel

It definatley isnt a 'free float' barrel but the question is is that correct?

Either it floats OR the wood clamps the barrel tightly right?

the wood isnt tight against the barrel...I can pull it away with a finger...but it does touch
 
All my 91/30 types are like that, contact, but not tight. Wish I could see it first hand. Just occured to me, shim under the action utill it floats the barrel, leave off the hanguard & see if it gets better.

I agree, check this out. There is a reason that so many of these rifles get counterbored. That would be my first guess.
 
With my short time with a MN, I found that they respond to accuracy tweaks very well.

Bed the action and the bottom metal/mag. Also, consider pillar bedding. Hollow the HG and stock so that the wood touches each other but the barrel floats (similar tech is used on Garands and Lee's). The triggers can also be lightened and tuned for a really nice crisp pull (I was amazed at how good these can get).

From there, test different ammo. I will assume there is no obvious problems with the bore. Shooting 2" with surplus is possible even with rough bores. I used Czech ammo mostly but also some copper coloured Russian stuff. The Czech (grey case with yellow or silver tip) shot really well.

Come on out...bring the dog

That sounds like a good plan...take off all the extra stuff and see what happens.

The bore and crown are very good on this piece.

I think the primary reason muzzles were counterbored was that was the first spot that started to rust (most exposed)

As for bedding the action.....duhhh....Ive never done that before. I would be willing to try it but on a gun that already shows promising accuracy

Is bedding a Nag easy or hard?....I might as well try it some time.Pillar bedding is the most difficult method, no?
 
It would be a bit of a haul, but I would if I could. Another idea would be to try this gun in a stock from another of your mosins. I have read about a guy that had a mosin that would shoot all over the place as it got hotter. He cut the barrel to sporter it & found the bore off center. Shot straight after he cut it(go figure). All else fails sell it & try one of the century bill board masterpieces from SIR.
 
Ya...

The cost of a Nag isnt much

It HAS to shoot good before I spend the bucks to mount this $500 PU scope on it

I cant be a Hero of the Red Army with a sniper that dont snipe....ya know?
