5.56/.223 Mosin Nagant?

Why you want smaller bullet for mosinka? Is not good enough as produced from izhevsk, tula, or sestroryetsk? Maybe you find job with army of russia, have many vodkas with sergei mosin and leon nagant and trade details of many weapons designed! But you no do this! Because you never design weapon in entire live! You look at beautiful vintovka, think too hard on weak capitalist shoulder, too loud on delicate capitalist ears! You think it need smaller american pea shooter bullet instead of glorious soviet 7.62! Why you think 5.56 better than oldest serving military cartridge in world??? This talk of decadent american capitalism! Maybe you put ### dildo on top to screw yourself for making shame of tough soviet workhorse! Leave rifle as is. Fire many round. Let rifle soak in drano. Make spaghetti. Watch octopus ####.
 
Changing the barrel, changing the bolt face then trying to figure out a magazine that will work. But Why?

Would cost far more that it would ever be worth.

7.62 x 39mm would be way easier, the barrel is already the right diameter inside and the Nagants have a very long barrel shank so you could take the barrel off, cut off the 7.62 x 54mm chamber, cut a 7.62 x 39mm chamber, re thread the barrel and put it back on the receiver. You would now have a single shot, figure out the bolt head, extractor and magazine and you have it made. Now, back to Why?

You can do pretty much anything with enough time and money. Doesn't make it a good idea, though.

like trying to breed a cat and a horse.

you would basically be building everything new onto just the receiver.

due to the size difference of the 7.62x54r case and the .223, I think it would be a LARGE under taking to say the least.

you would need:
new barrel
new mag follower, presumably shortened
new bolt face / new ejector.

There might be some serious bolt face re-design considerations due to the fact that the 7.62x54r is rimmed and headspaces as such.

I've read about some other conversions, such as .303, 30-06, 45-70
but nothing really working it's way down so drastically.

just my 0.02 I'm certainly not a gunsmith or an armorer or anything of the like.
 
Yo my homie lil billz got one of dem gunz. He say dey aint accurate cuz da barrell be too large and da bullit be bouncin around when he shoot it.

Have you instructed lil billz on the proper way to handle, operate and accurately shoot a firearm? I'm sure with practice he can be accurately shooting up his hood with his .223 Mosin in no time flat. Nawwimsayin mayne?

But on topic, you could do it. If they could make a Lee Enfield go full auto, you can make a Mosin in .223, but I gotta ask: Why? Let's call it 150 bucks for the Mosin, then at LEAST 500 dollars for the gunsmithing and parts, and you're looking at a piece of destroyed history that I guarantee won't shoot very well at all, for way more than a .223 bolt action from Savage or something. Again, you can do it, but that doesn't make it a wise or cost effective decision.
