SOOOOO many people think that a scope creates accuracy - it's possible you just have a MYRIAD of problems that can happen with any gun.
I bought a book on home gunsmithing that showed a lot of things you can do without major equipment to increase the accuracy of any rifle.
It MIGHT be the rifle, so you'd have to rule stuff out.
First and foremost, I'd shoot 10 rounds at 25yards from a bench over your iron sights. See if you can even get close to a group.
Second examine your crown, a LOT of imported mosins have crappy crowns, which is to say that the lands and grooves (both of them!!!) are uneven upon reaching the crown of the bore-use a jewelers loupe for this exam. 90 percent of the time you'll find damage, which can majorly affect each round in a different manner upon exiting the bore. Recrowning is cheap, and you can even get a brownell's kit for it. I'm assuming a pepperoni pizza pattern, with the rifle shooting all over the place - every time I've seen a mosin do this, it's been at least partially attributable to crown damage.
Can't hurt to look!
But geez guys, just because there's a scope doesn't mean a gun should shoot a group!
I remember the overtorqued barrel syndrome some AR's had about 15 years back, olyarms and bushhamster had to fix a few rifles where they'd cranked things too tight. Wasn't endemic though.
geez I'm old.
OH, and check your headspace, excessive headspace will ruin accuracy too, excessive headspace isn't a huge issue for nagant's, as it is in an autoloader. A gunsmith MIGHT have the gauges, or someone here might. Check the locking lugs for full engagement also, sometimes the shoulders get damaged and they lock up unevenly (for each round) and that also creates pizza's.

Thanks for all the input and info guys. I'm on paper but it is still not as good as it should be. I will check into some of those things listed in the last post. I don't know if I stated it before but with the irons it was fairly accurate. Maybe I'm just not a scope man? Haha
