Picked up a very nice 1945 dated Ljungman m/42B. Before taking this to the range have been doing a bit of research here and elsewhere online.

From this translation of a Swedish Army manual http://www.nazarian.no/images/wep/181_agmanual.pdf it seems the rounds need to be oiled before loading:

Lube the magazine with # 042 lubricant. Cartridges and action should be lubed when loading the rifle.
During longer firing pauses the chamber should be cleaned with the tool and lubed with # 042 lubricant.

Does anyone know what "#042 lubricant" was, or what can be used as a substitute?

Here's some info that's a bit disturbing: http://en.wikipedia.org/wiki/AG-42

Use caution when firing the Ljungman and Hakim rifles as the burn rate of the powder has a dramatic effect on the operation of the rifle. There have been reported cases of catastrophic failures of both these rifles when fired with incorrect ammunition. Even the Swedish m/41 ammunition was required to be lightly oiled by Swedish troops prior to loading as the burn rate of the powder is too slow and the oiling of the cartridge body facilitates extraction.

The main dynamic involves the pressure curve and the timing of the pressure curve as it relates to the location of the gas port in the barrel. While the Hakim has a gas port adjustment the Ljungman does not. As the bullet passes the gas port the gas pressure is channeled back to the bolt carrier to unlock the bolt. With a powder that is too slow a burn rate the bolt carrier opens violently premature and at an extremely excessive pressure. What this does is causes the extractor to tear the rim off the cartridge case exposing the action to the dumping of very high pressures which typically exits the action downward into the magazine well blowing the magazine completely out of the rifle and often destroying the magazine and stock in the process. Pay close attention to use the correct ammunition in these two rifles.

Oil on the cases or in the chamber & barrel is not usually good for accuracy. Anyone here oil their ammo, or have comments on accuracy & functioning with or without oiled cartridges?

Are faster burning powders than the original Swedish ones going to solve this problem, or do the rounds and chamber need to be oiled regardless?
 
I've never oiled any of my rounds. I reload and use Varget as my powder. I've never had any cycling issues other than forgetting to clean the chamber after a lengthy load developement session. My only beef with the Ljungamn is brass retrieval. It's pretty much non-existant. Congratulations on you purchase. It really is an underappreciated gun and calibre.

Not to hyjack the thread, but has anyone been able to successfully scope thiers, to make for an accurate long range rifle? I've been wanting to get one for a while for coyotes and wolves, but with open sights, it's not really an option. I love the 6.5x55, and I love semi's, but I'd need to be able to solidly put a varmint scope on one before I could justify buying one.
 
I have fired 100's of rounds from my Ljungmans and never lubed any of the cartridges. The only failure to extract I ever had was way back when you could get Swedish military surplus ammo, it had a chrome colored projectile, and one case stuck so bad I broke the extractor. Luckily my gun had come with a spare parts kits and I was able to replace it. After that I mostly shot Yugoslavian Prvi Partisan fmj and Norma match grade ammo and never had a failure to extract with dry ammo.

Northman999, we may have talked about this previously, but I did make a "one off" custom mount that screwed to both sides of the bottom of the receiver by drilling and tapping the receiver. Shot many rounds through it and it was reasonably accurate. I sold the gun around 7 years ago. Its too bad I never made any photo's of the mount. Probably a lot of people here would have frowned upon it, not because it looked bad, which I think it didn't, but because it required drilling and tapping the receiver and removal of a notch of wood on each side of the stock. It was very much like an M14 scope mount, but it bolted to both sides of the receiver. You could see under it to use the iron sights as well.

I love to post these pics, they were posted on an on-line auction site a while back, I still don't know who makes this mount.

They did come with an oiler in the tool kit, as well as a tub of grease. Never would have thought of oiling ammo. That sound really impractical during wartime. How do you keep your spare ammo lubed and clean? And keep the chamber clean?

We fired large quantities of ammo through my guns at Virden's bowling pin shoot during the alloted time, and not a single jam or failure under rapid fire conditions using dry ammo. I definately question the necessity. Lube and cartridge cases usually don't mix, other than resizing cases.

The Hakim is basically an AG42b in 8mm. Here's someone's Hakim sniper project. Might give you some ideas:

The Molot mount from Kalinka optics might be an option. You wouldn't have to cut the AG42 stock for it (compared to the other Kalinka rails that bolt to the reciever).
 
There's a member on this site, talked to him last year but forgot his phone number and name:redface::bangHead: Who customized his ljungman. Looked quite spiffy - I believe he bridged the reciever completely with a piece of thick steel. He may chime in, had a lot of good info.

Here's what people have done with an hakim, which is similar:

Note the brass deflector built into the mount.
