    12,7 mm APFSDS with sliding stabilizer

    Hello,

    I want to share an interesting 12.7mm APFSDS round with a sliding stabilizer. It's a Czechoslovak experimental from the early 90's. Testing was done with 50 BMG and 12.7 x 108 casings.

    ffe of course

    If you go a bit smaller (but not by much) the Bigot conversion kit for .45 ACP had exactly the same idea for a sliding set of fins. Only difference was it was fire from a spigot, so no need for the sabot.

    Something not kosher looking to me about this one. I could be wrong, but my spider senses are tingling. The fact that the fin assembly is almost if not the same diameter of the bore is unusual. I hope someone here can figure it out. Its really cool and so different.

    So True!

    It does remind me a lot of that. Except the spigot has the fin assembly outside the guns bore and this gets fired threw the bore. Those finds look od to me for that purpose. Still, it may be 100% a real cool R&D design.

    It's 100% original. I don't know what kind of results it was getting, it could have just been a study. I have another similar sample in my collection using the same principle, both from a similar period.

    I'm not home right now, but I'll measure it over the weekend and add the dimensions of the whole assembly

    I believe you 100%, if you say it's real. It is just such an odd design. It's beautiful for sure. I hope it gets ID'd. :-)

    Thanks so much for these measurements and close up photo, Pavel.

    Truly a super unique, out of the box thinking, incredible design. In all my years collecting, inert, APFSDS specimens, I have never seen anything like this. Just off the charts bad ass amazing :-) Blown away!

    Does the projectile come out of the case? I wonder if the sub-projectile has a longer body between the sabot petal with the possibility of a second fin assembly inside the case?
