is there any other headstamps known for the 7.62x41mm other than 543 6 43 6 and a no headstamp?

here are all known (at least to me) head stamps.

Could any Russian speakers translate/summarize that article into English? The Google translation is atrocious.

This is a Google autotranslation, I’ll go through it later and try to correct (if needed) or maybe someone else (who is not busy at work) can do this too:

In the Soviet Union in the early 40-ies of the last century, is actively studying the experience of the successful application of intermediate rounds in the armies of other countries. In the OKB-44 began developing its own intermediate cartridge designed for the shooting of the projected under his semi-automatic weapon. The cartridge was designed to defeat open or sheltered small obstacles live targets at ranges up to 1000 meters with accurate fire up to 800 meters. By 1943, was designed by 7.62 mm with a sleeve length of 41 mm, which had bottled form without serving chimes. Bullet cartridges were filled with lead core. Compared with the rifle cartridge, the new cartridge has the following advantages:

1.Umenshenny weight cartridge allows you to increase the ammunition carried by fighter 1.38 times (weight of 100 rifle cartridges equal to the weight of intermediate 138 rounds).
2.Oblegchalsya weight weapon, designed under the intermediate cartridge.
3.The 1,000,000 cartridges provide cost: bimetal ≈ 4 tons of lead ≈ 1,5 tons and tons of gunpowder ≈ 1,5.
For field testing in 1945 was granted a cartridge with a bullet with lead core bullets and several options with explosive bullets. Cartridges were filled with gunpowder experienced brand VU developed by specialists of the Kazan gunpowder factory. The tests were completed by October of the same year and ammunition have been approved by the troops. But the GAC and the IEC endured a joint decision on the continuation of tests to find the optimal caliber ammunition. At the new trial was granted 8 sample rounds of ammunition, including ammunition caliber 6.75 mm and 7.62 mm. During testing it was found that the best ballistic properties demonstrated caliber ammunition 6.75 mm and 7.62 mm long sleeves 50 and 60 mm. But because of their dimensions, these cartridges do not have significant advantages over the rifle cartridge. Since for rounds of 6.75 mm by the time the tests were carried out not by the knockdown and stopping power, these munitions were rejected.

During the tests it was noted insufficient effect ArmorPiercing lead core bullet design flaws and liner - thin wall in the sleeve bore and dulcitol. Cartridge design was finalized, and the results of field tests for serial production was recommended upgraded intermediate cartridge with a sleeve length of 38.5 mm and a bullet with a steel core. Experienced bi-metallic sleeve chuck with a length of 41 mm were produced munitions plant number 543 until June 1945.

Here is my adjustment of the above auto translation, not that bad for a computer. I also need help, don’t remember what the meaning of проточки is at the end of the text. May someone from Russia/Germany correct/expand on this word and the rest of the text?

The successful application of intermediate rounds in the armies of other countries was actively analyzed and studied in the Soviet Union in the early 40’s of the last century. OKB-44 began developing its own intermediate cartridge designed for a semi-automatic weapon meant for this cartridge. The cartridge was designed to defeat unprotected or small-obstacle-protected live targets at ranges up to 1000 meters with accurate fire up to 800 meters. By 1943, a 7.62x41mm bottle-shaped rimless cartridge was designed. Projectiles were filled with lead core. Compared with the rifle cartridge, the new cartridge has the following advantages:

1.Smaller cartridge allows to increase the ammunition carried by soldiers 1.38 times (weight of 100 rifle cartridges equal to the weight of intermediate 138 rounds).
2.The weapon designed for this intermediate cartridge would be smaller (lighter) too.
3.Per 1,000,000 new cartridges the savings would look like this: bimetal ≈ 4 tons, lead ≈ 1,5 tons and gunpowder ≈ 1,5tons.
A cartridge with a lead core bullet and several other explosive bullets were submitted for field tests in 1945. Cartridges were filled with a new VU brand gunpowder developed by specialists of the Kazan gunpowder factory.

But the GAU and NKV issued a joint decision on the continuation of tests to find the optimal caliber ammunition. 8 sample rounds of ammunition were submitted for new trials, including ammunition caliber 6.75 mm and 7.62 mm. During testing it was found that the best ballistic properties were demonstrated by caliber ammunition 6.75 mm and 7.62 mm with cartridge length 50 and 60 mm. But because of their dimensions, these cartridges do not have significant advantages over the rifle cartridge (7.62x54R?). Since tests for rounds of 6.75 mm were not carried out to establish the knockdown and stopping power, these munitions were rejected.

During the tests it was noted insufficient AP effect of lead core bullet, and cartridge design flaws – thin mouth wall and проточки. Cartridge design was finalized, and the results of field tests for mass production were to recommend upgraded intermediate cartridge with cartridge length of 38.5 mm and a bullet with a steel core. Experimental bi-metallic cartridges with a length of 41 mm were produced at munition plant number 543 until June 1945.

It means groove.


#7

Did these rounds ever hit a battlefield?


#8

I don’t think so. it was experimental cartridge.


#9

There’s a gentleman on another site that is sure that one of the “battlefield archeologists” will find some. I suggested that he not hold his breath for that.

If the word protochki [groove] in the original Russian text was modified by the adjective “thin” then perhaps the sense intended was that in the original experimental cartridge the rim was found to be insufficiently durable and was made thicker. In the 7.62 x 41 m/m R cartridge case is the rim thinner than in the final 39 m/m version? Jack
