I have a couple of Mosin 91/30s that I want to put some new heavy barrels in.

I picked-up two new vz-59 re-threads few month ago. These are brand new chrome lined 24" with threads and ejector groove already cut. Seller advertised as drop-in ready. I would not undertake this kind of replacement on my own, I'd rather have qualified gunsmith do it. Also these need to be turned down on the lathe, since they're way too thick and heavy for a rifle.

Anyone can recommend someone who doesn't charge arm & leg? Also if somebody had done similar work in the past I'l like to know a price range for this kind of job.

Thank you for the input guys.
 
If you want a heavy barreled Mosin - just get an M39. Turning down a couple of heavy duty barrels for your 91/30s is going to cost a bit.
 
I have seen similar builds on some sniper forums. No idea on price, but they came out wicked nice and very accurate, because stock barrel does whip a bit, so this is a worthwhile things to do, but the guys did it on their own.

Any way you can share what you paid for the barrels?

That was exactly my idea - nice super heavy barrel, solid aluminum billet for a bedding block and custom modular synthetic stock.
And if this venture fails - i didn't loose a ton of money, since all parts that went into it are fairly inexpensive. but if it works then i have nice target rifle somewhat unique and totally customizable. Chrome lined bore is an added bonusto shoot corrosive surplus. someone might say it won't be as accurate as SS heavy barrel, but I's I take reliability and longevity over marginal accuracy increase any time. after all this is up to 300m - maximum what my range allows.

even if i put another half a grad into this, i'm planning on saving using surplus ammo. if it's gonna turn out accuracy simmilr to stock savage 10fp i'll be plenty satisfied and still be in the win for having really nice custom gun for a price of stock one. even if i spend a grand on it it'll still would be worth it.

as long as i get to rub it in the face of body of mine who thinks Mosin's are just shitty commie crap not worth the money people charge for it. just want to prove him wrong.

Memory serves me it was something around $70-80 a piece plus S&H
 
was that recent purchase? $80 per bull barrel seems like an awesome deal. Found one link:

the problem is that after all the modifications, the only original on it is action, so it's not exactly a combloc rifle, only in the name. Handloading ammo would improve things a ton, even if it's pulling apart surplus ammo and replacing bullets, measuring powder charge.

Why are you going for a milled Al bedding? I'd think that cast Al bedding made from actual action as template would literally fit like a glove if you want to go Al route. I still think that epoxy cast bedding would mate better and is easier to do.

to my knowledge it's just shortened version of 91/30 no heavy barrels on those. at least i've never seen one that had heavy bbl

You should expand your Mosin knowledge. The M39 was a Finnish service rifle built off of captured Soviet Mosins. They have heavier, bulkier stocks, heavy barrels that were occasionally bedded with shims, and new sights. They're probably the most accurate out of all the iron-sighted Mosin variants there, and they're not expensive. Some say that they're the best all-around incarnation of the Mosin Nagant (I'm one of those people)

I don't care about originality. I simply chose MN because it's cheapest one and one of the most robust actions out there. Plus I haven't seen any brand new heavy Mauser barrels that are chromed and $80 bucks a piece. Last but not least is the caliber - 7.62x54R is very capable round and surplus is plentiful and cheap and of a very decent quality.

My idea behind this build is to make sturdy aluminum frame/bed that you bolt your action to. with more than two original bolts. this will hold it just as secure as epoxy bedding. aside from that it'll be making entire thing much more rigid frame will also serve as a skeleton on which stock parts will be 'hung'. I'm here dare to step away from conventional approach. polymer or wood would be used just as a furniture to provide you with grip and nice surface to put your cheek against. I also do not exclude possibility of fabricating a butt stock spring-loaded multi-stage buffer in addition to regular rubber recoil pad.

Casting aluminum is sort of out of my comfort zone. casting while provide good fit (assuming you have capabilities to cast your own metal) is poor substitute for forged T6 7075. not to mention casting has high potential for embedded cavities and up to 8% shrinkage of the final piece.

I think barrels are still available on gunbroker

I have to agree with him, I have one and prefer it over my 91/30. The sights are better, and its very accurate. Farthest I've ever shot it was 500 meters (maybe yards, not my range can't remember) and 3'x3' steel plates weren't hard once I found it in the grass.
 
I say build the beast.....they have those crazy bulpup stocks for mosin that might just fit the bill. I would consider one of those barrels if I had time and resources. Right now my time and resouces are zero.

I say forget about machineing down the barrel leave that honkin tank barrel on there. Build a shroud around it like this guy above.

this is probably what I would end up with.....I think I have those spare parts in my parts bin http://www.youtube.com/watch?v=0LEXGySwviE&feature=related

I get less than 8% shrinkage by just eyeballing the temperature, with some thermometer control it could be done to very high tolerances. I would consider various alloys too. As core, I'd use dental grade plaster, the same thing they use for casting crowns, so we are talking microns in free play. That's not something you can get on a mill, because all surfaces won't be all square. That's a project in itself though. I like the Al frame, I was going to do something about getting one for my 10/22 since every one one the market (and there tons of them) suck in terms of fit (I was looking for a big hand pistol grip etc)

I may have been lucky on my Mosins, the last one I shot, I was getting 1" groups at 100 yards, from lead sled. That's way beyond what my vision is that far with iron sights never mind shooting off hand.
