Ok today i decide to take out the old girl to the sand pit and put around 40 rounds of czech surplus through it. The second round i fired jammed inside the rifle. the bolt was all the way forward and i could not #### it to take the round out. And without a gunsmith with-in 30kms and a small doubt of a live round in the chamber. only thing i could think of doing to extract the round was to bang on the cocking handle till it came out. Can someone explain to me what happened and how to possibly deal with it safely if it happens again? Thanks

PS. also got a problem with the cleaning rod always unlatching after i fire a few rounds. the button holds it secure i cant put it out with my fingures so yea. anyone else have this issue?

Your gas setting is not too high? First time you fired czech ammo with? I guess the czech ammo are lacquered steel case right? Be sure to clean the chamber very very well because the lacquered case and the fluted chamber of a Tokarev might not be always doing well together. As for your cleaning rod, never happened to me yet.

ive put at least 400 surplus czech before hand and few 100 mfs. as for cleaning it to the bone with windex, CLP and a good old 7.62 bore brush :) gas setting is at 1.1 which usualy cycles the surplus good
 
Could be an out-of-spec round: casing too big. Remember, the East Bloc retired the old MNs and SVTs right after War Two, so any ammo made in the last 60 years or so has been for MACHINE-GUNS and generally is made to looser tolerances.

Windex is made for cleaning GLASS. Glass is Silicon Dioxide, SiO2, which does not contain IRON.... which rusts. It is NOT the best thing for cleaning a rifle with.

The inside of your chamber, especially the FLUTES, will be crudded-up with LACQUER from your last 400 rounds of Czech MG stuff. That's what glued your round in. Russian war-time ammo was Copper-washed and did not have this problem. Stand the rifle in the corner, plug the chamber with a cork and pour the barrel half-full of Acetone or Lacquer Thinner and let it stand for 48 hours, then remove the cork, pour the stuff out and scrub the daylights out of it.

Hope this helps.

Ah ok the eternal wisdom of the internet suggested me to use windex after the use of corrosive ammo, and if you got a giant mole on the face (my big fat greek wedding). So this brings me up to a new question... Corrosive ammo, how to remove the corrosive stuff in the rifle after shooting?
 
Boil two liters of water , remove bolt from rifle, get flexible hose and pour water down. Keep muzzle off of your foot unless you like burns and keep it pointed towards the wives flower bed.

Then clean as per normal. water will flush the salts out of the barrel and then use Hopes to clean out the powder and other residue
 
Hmm, I used to be a member of the Hungarian army, when I was young.;) I never ever seen anyone boiling water after a life fire shoot, to clean the AMD-65s. Never ever!! Scrub it with gun oil, dry it and that's it. Never seen any of them with rust anywhere.

It probably isn't required. A lot of people just do it because it's an investment we want to protect so we go above and beyond. I'm sure in service use it wasn't done much at if it all in the communist bloc. Thanks for your story, cool to hear. Got any more? :D
 
:)

Off topic. Did you know, 8 guys can push a BMP1 on a flat ground?:) I didn't know it either, until we were yaping a bit too much in line.

Same thing happened to me... had to get a big stick to whack the charging handle to extract the round. Turned the gas setting to 1.5 & all has been well.

Might be 2 reasons for that - you cleaned your rifles right after the live-fire session, and the barrel and chamber might have been chromed.

Was the BMP1 the one that had the gas tanks in the back doors??
