Czech 7.62x39mm surplus cutaway reveals.______

. We are talking Czech ammo which is sort of untypical of M43 as it has a leaded gap between the copper and the large steel core

I believe the bullet as you are describing it is a typical M43 projectile. I've lost the source, so I won't suggest it's gospel. IIRC, the formed steel or copper jacket moves down the assembly line nose down, then a drop of molten lead is introduced, followed immediately by the mild steel core. The molten lead fills in the gaps and solders the core in place, then the jacket is swaged to form the base.

Commercially packaged Norinco (yellow box, 1990's production) came with this style of bullet. IIRC, the three part construction was one of the factors that led to this ammo being banned from import into the US, before the Exectutive Order banning all Norinco military style guns and ammo. As a rifle ammo, it would have been fine. The problem IIRC was Olympic Arms began offering a 7.62x39 chambered OA-93 pistol. Once BATF lumped this caliber in with pistol chamberings, the AP legislation kicked in and imports were stopped. I seem to recall a very irate Cameron Hopkins of American Handgunner lambasting Olympic in print over this.
 
ohk the M43 style bullet is of russian design and according to several sites and has a small air gap at the front, I AM NOT SURE on the correctness of this info. Czech doesn't have this and has the steel core up tight against the front of the shell, some sites list it as being based on russian design but not totally M43. Again it looks to me to be pretty much M43 as you say :)

I am getting some ( a few boxes) norinco yellow box today, hopefully some still left ! I know of a person who has a wack of it for sale at $6 a box. :mrgreen: If the czech can do a 5/8 soft steel @ 68.58m the norinco will do a better job as it has more fps !! :mrgreen:

Sparks come from every steel core round, typically Sov block - no conspiracy theory....and no, M43 rounds still won't penetrate 5/8" plate at 75m....

You are right, won't even penetrate 3/8 steel....
Did some more shooting today, BXN 69 this time, made a slightly different hole, no penetration. It just doesn't have the SD or the velocity......

really.. what distance are you shooting at and what type of steel are you shooting at ? Weird is this Czech surplus?.. I have yet to do the official test myself with pictures... I just am curious as to why other people ( like me) report Czech wizzing through those gongs at 68.58m, as I have seen this happen on a number of occaisions.. I am also wondering if some batches of ammo are loaded a bit hotter than others... could this be a possibility? True, Czech has low velocity 2200fps-2300fps. hmm now you have me wondering if what I saw is possibly an ammo mixup (norinco in a Czech box) or just a hotter batch of Czech.. :?: :?: :? :? :?: Tommorrow is the big day. We will see soon enough.

You are the only one claiming that it will shoot through 5/8 steel plate....
I'm claiming it won't even shoot through 3/8 steel plate, with pics, tests, witnesses, etc. I gave you the headstamps of both ammo selections I tried. If you don't know what BXN is then you obviously don't have any Czech ammo.......
I'm tired of this. Put up some proof, or shut the #### up about this armor-piercing Czech 7.62x39 that has gone from penetrating 1inch of hardened steel plate at 150 yards, to 5/8 at 75 yards, to god knows what the #### next.......
All you do is spout off bull#### like it's going out of style.......personally, I don't think you know piss from paint......
 
Let us end this..

plz.

Targets are crappy (Fe) metal as monkeyman says.
I enjoyed today, meeting monkeyman and the other Gunnutz.. this is how this forum should be.
Today was the most fun I have had in months. lest us continue this path. :wink:
 
Was out at the JDF range today. The gongs up there look like swiss cheese. They sure as hell aren't using high hardness steel. Whatever it is, I was penetrating straight through with my AR at 122yds.

'Twasn't some fancy bullet, just crappy targets. :wink:
 
Buddy of mine was a comando in the Czech army behind the iron curtain, he said when they got the SKS they took them out and demonstrated how it would shoot through the web of a railway track. Sounds like he was not stretching the truth.

Oh for crists sake......... :roll:

When did the Czech army ever use the SKS? Shoot through railway ties? Give me a break...... :roll:

This is what Czech 7.62x39 1969 manufacture surplus will do to a 3/8 inch steel plate at 100m..... makes a good dent, but no hole through.....

Okay, I seperated the projectile from the casing ghetto style (bench vise and vise grips).
I then grinded the projectile such to only reveal the different layers.
Here are my findings: copper coated steel jacket, followed by lead lining and finally followed by the steel core.
The steel core is most likely just a piece of wire.
More to come since I intend on doing a Rockwell test during the week.
Too bad I don't have one in the garage.

Cheers,

Forget the Rc test.
After putting a few file marks on the core, I can safely state that it is as soft as butter.
As I suspected, it's simply a heafty piece of unhardened steel wire.
Mystery solved and I learned someting in the process.
Sorry no pics, I sent the camera bck to for repair. :oops:
