Ljungman slamfire?

[glycerin]

Has anyone experienced firing on feeding of federal-primed reloads. Most alarming, no trigger, honest! I suspect firing pin return spring isn't strong enough to prevent firing pin from tapping primer when breech slams home. My CCI regular large rifle primers show a light tap mark from pin but don't slam-fire. Be careful. I expect SKS could be more dangerous because it has no pin return spring.

The Ljungman is notorious for slam-fires and out of battery primer ignition. You need to switch to CCI No.34 milspec primers. The Federal (and all others but the milsec primers) are too soft for the Ljungman's feed system.

The SKS should also use milspec primers. It's less of an issue b/c very few ppl handload for the SKS.

Was the Ljungman ever made in full auto? I ask because a guy once told me he bought one that was that way...as in selector. Is it possible he thought it was full auto because it would slamfire? Or did they come in FA version?

I always found those rifles too long and clunky for my tastes...quite the long stroke action on those rifles.

[Claven2]

I'm no Ljungman expert, but I don't think a F/A version was made in any numbers.

As for slam-firing, it theoretically shold only do so once and the bolt would then lock back... unless the sear wasnit engaging AND it was slam-firing every round. Unlikely at best for this to happen by accident.

I've never heard of one. There were selective FN 49s.

No Full -Auto Jlungmans. Check your head spacing blocks for wear. Are you having any stetch marks on the fired cases? Are you lubing the ammo?
Excessive head space and dry ammo will cause a slam fire at times. I have fired many a thousand rounds out of these rifles with no slam fires.
Springfield Sporters will have all of the head spacing blocks as a kit for under 20 bucks US. Mine was so sloppy, cases were tearing at the base/web union.
As for lube, I use Bordens "Slide-All", a dry film that will not kill primers or attract dust. Cases fly out of the rifle for 20 meters. Good luck.

20 metres?? Sounds like being beside a Ljungman on the firing line could be hazardous...

I did look at them about 20 years ago but never wanted to own one. The guy that told me that story stuck by it. For all I know it was just slamfiring.

the only thing I have that is close is the Hakim, it to delivers the brass into the next century. Once recovered, completely useless, crowbar comes to mind. Its quite a blast to shoot, but, only do it on occasion. The design most definitly lends itself to slam firing. As for case lube, I had suggested this in the past and was informed of pressure issues, seems strange, however. This was commonly done during US trail rifles in the mid 1920's as a means of keeping the feed on certain semi-autos reliable. Either way a lot of good things to try in the above posts, my first would be the spring and then H.S. HTH-SDH

Whomever brought up the pressure issues with a lubed case and the Jloungman is so far off base from the truth it aint funny. These rifles were issued with a special oil to lube the ammo before use. Firing this rifle ,the AG-42B with out lubing the ammo is really asking for trouble. The rifle depends on the added bolt thrust to help clear the chamber of the fired brass. The Russians looked long and hard at this design when they captured these riflesfrom the Finns. They knew that any lube would be a big problem in their Russian winters. Therefor, they fluted the chamber neck and shoulder on the SVT 38/40 to prevent the case from having it's rim torn off by the op rod and thus did not need to lube the cases.

Wasn't the SVT38/40 designed and in service before the Ljungman? Hence the "38/40" these being the years of design or at least introduction? Seems more likely the Swedes brought some SVT38/40s back from the Winter War (1940) and things went from there. There were Swedish volunteers fighting with the Finns etc.

Wonder how much the SVT38/40 owed to the Fedorov of WWI?
