I have a hex receiver Mosin Nagant. I'm not concerned with preserving it's historical value as I believe it has very little. I'm looking to mod it out to be as accurate as possible. I want to install a heavy barrel but have no idea where to start. Has anyone any experience with re barreling a mosin?
Mosin Nagant Heavy Bull barrel conversion?

Bad idea.
Better to take a cheap modern precision rifle with your own reloaded tailored ammo. you save on the time/effort/money/headache/disappointment.
Plus Mosin action is not a good one to go to the precision way.
When the Finns wanted a new sniper rifle, they tested everything that was available. Then they built up their own, selecting Czarist period M1891 receivers.
Search for the Finnish TKIV 85.
Yes, a precision rifle can be built up on a Mosin Nagant action. Yes, a custom barrel can be fitted.
But unless you do the work yourself, the cost is going to be substantial.
Your project. If you want do it, go for it.

If you wanna chop it up, just cut/re-crown it down to 18.5"{+} or so, still will shoot about the same as it does now 
- For Budget accuracy, even a Savage Axis would be a better starting point in /.308. & you can dress that pig up with a ton of aftermarket stuffs.

What you really want is a nice Finn M39.

Funny how this works: Someone posts "I want to do this, how do I go about that?"
Lots of people "You don't want to do that!"
And people profess to be libertarian leaning around here
MosinMan: McGowen makes barrels suitable for 7.62x54R...

Thank you for all your opinions and advice. For me half of the fun with firearms is modding them out and making them my own. If you can guess by my handle I love mosins. I've had several throughout my life. However I have never re barreled one before and was looking for help. TBH my money, my gun, my time.
I've heard of mccgowen barrels for the mosin, does anyone have some knowledge to share about them?

A whole pile of Olympic shooters from 1960-1977 would disagree on that. Get a nice action & blueprint 'er. The Finnish ones had the best triggers of the Mosin Nagants and the Russian Olyimpic models used the same trigger setup.

The Czech VZ 54 makes for a dandy gong smacker as well. Ain't very common though & too valuable as is to collector types.

This guy hunts with his.
That's a good point. If you're putting a new barrel on it, going with a 308 bore instead of 311 or whatever would be a good idea.
Same rifle as last year but modified a bit more, shooting MFS 203gr soft points.
1943 Mosin Nagant 91/30.
Barrel cut and crowned at 19".
Archangel Target Chassis
TrueShot see through scope mount.
Nikon Buckmaster II 4-12x40 With BDC Reticle.
Bent bolt.

I've got an old Finnish mosin that somebody butchered, I can't get rid of it. The action and trigger are smooth, so it would be good for a project like this.
I'd hate to see another rifle destroyed. So if you want to trade, we could work something out.

Mosin Nagants I would argue are actually one of the most inherently accurate Milsurp rifles. Provided the bore, and crown are in excellent shape and the ammo is good quality (I.e. Not the surplus junk) they can really perform well. I remember doing a 1.5" group at 100m with some hand loads though a M38 carbine with irons.
Most the bad rep comes from rough rifles being used by inexperienced people with surplus ammo. Once those factors are removed the rifles tend to perform very good in the accuracy department (mind you they are still a crappy action).

We Target Rifle shooters and F Class shooters use heavy barrels. We repalce them whan accuracy starts to go.
One of these barrels can be had for $100.
Cut the chamber off. Cut new threads and cut a new chamber. This will get rid of 2" of throat erosion and give you an almost new barrel.
The barrel is 28 to 32" , so you may want to cut a few inches off the muzzle end, too.
And load with 308 bullets.
I have done this with Lee Enfields. I call the result a 308Brit.

.308x54R?
Having a lathe, I've been able to experiment with all sorts of barrel fitting. Take-off barrels can be bargains, and with a new chamber will shoot well. Catch is, if a 'smith has to be paid to do the fitting and chambering, the cost is the same as it would be for fitting a new barrel. Many folks question whether money should be spent fitting a used barrel.
Then there is the issue of the reamer. If one isn't on hand, and one has to be ordered, the cost goes up.
