if you mean this quote, it means “ammunition for rifled guns”.
НАРЕЗНОЙ in this context means rifled;
НАРЕЗНОЙ СТВОЛ - rifled barrel,
НАРЕЗНОЕ ОРУЖИЕ - rifled guns (long guns and short guns, generally)
НАРЕЗНОЙ ПАТРОН is sort of slang, which means cartridge for a rifled gun.
Brian, thanks a lot for sharing.
Regarding the 7.62x25 CB and KC (cyrill.) I think you have swapped the Google translations.
The CB cartridges (SV in English) with the brass cases have the shorter bullet with them. I think this is the lead core version.
The nickel finish cases (KC, or KS in English) show a longer bullet as expected from a steel core bullet of the same weight.
Frank’s question is referring to the sentence (page link: http://techcrim.ru/?page_id=328) shown below in the screen shots. The first screen shot is in the original Russian text (pointed out by red arrow) and the second screen shot is the Google translation (pointed out by blue arrow).
In this particular case, “НАРЕЗНЫЕ ИСПЫТАТЕЛЬНЫЕ ПАТРОНЫ .223 Rem” means “Test cartridges for rifled guns, caliber .223 Rem”
Those are specially loaded to higher standards to be used as yardsticks when testing new guns for performance and accuracy. Note that those are standard pressure loads, as opposed to Proof loads that generate higher than standard pressures.
What I saw was regular hs. Image was too blurry. Not very exciting in my view. I did not even dare to save images and really means something.
Unlikely to see unissued lots as that never happened with anything Tekhkrim ever had in it’s hands.
Also do not forget that the material they have usually is surplussed material contracted for disposal.
That’s exactly what I was hoping to see!
This is the first evidence I have seen of 270 * 52 * with stars (are you sure of the stars?), T ^ 45 XI, T ^ 45 XII, and 270 * 46 VI.
Now I just need to find some for the collection!
Another headstamp that I saw in recent years -not from Techcrim boxes- is T △ 46 V, which should not be confused with T △ 46 △. The “△” in the former is pointing inwards and in the latter are pointing upwards.
