Very nice, but it would seem to be the wrong projectile for the 3UP5 (3УП5) round, which is abbreviated to UP5 (УП5) on the cartridge case.
The 3UP5 round should have the 3P8 (3П8) practice (inert) shaped charge (aka inert HEAT) projectile, not an inert high explosive projectile based on the 3OF18 (3ОФ18).
For note the long neck is so the fin stabilising unit at the rear of the projectile assembly is supported correctly during the initial stages of firing; i.e. as it transitions from the case to the bore.

Yes I no as the projectile did have fins on the base

I'm not sure what the above post is for, as there's no textual reply?
I could see the markings before, albeit smaller, hence my comments that the projectile fitted is incorrect for round markings seen.
ПРАКТ = PRAKT = round nature (i.e. practice).
УП5 = UP5 = truncated version of the round's 3UP5 (3УП5) GRAU index code.
115-У-5ТС = 115-U-5TS = calibre (115 mm) and weapon (U-5TS tank gun) the round is intended for use with.
ДГ-3 13/1 5/76 Ц = DG-3 13/1 5/76 Ts = propellant type (DG-3 13/1) and its production details (5/76 Ts).
51-77-53 = complete round production details.
Transliteration undertaken using the BGN/PCGN system. Other transliteration systems may produce different results for the Cyrillic Ц character.
As mentioned the 3UP5 round, which is truncated to UP5 on the cartridge case and packaging, is supposed to use the 3P8 projectile.
The 3P8, truncated to P8, is supposed to be based on the 3BK4 HEAT-FS-T projectile, and not an inert version of the 3OF18 HE-FS as seen here.
The 3BK4 and 3OF18 do not look the same, and hence neither do their inert versions.

Perfect as it''s got the correct 3BK4/4M-like practice projectile. This with a GPV-1/GPV-2-like dummy fuze, a two-part nose, and a wide forward bourrelet (bore-riding surface).
I couldn't find any images myself, but frankly Google search is pants now, and the original image of the round in the Wikipedia Commons was incorrectly labelled as an OF-11!
I corrected the Wikipedia Commons image (link) with the projectile image seemingly coming from the Russian Stankomash Plant (завода «СТАНКОМАШ») Museum (link).

Don't think I've ever seen one, as a photo or as a diagram?
It's mentioned in manuals, such as the manual for the V-429E, which just say it only differs in the design of the cap.
The cap, according to how the manual describes it, would be like that seen on the GPV-1 and GPV-2.
I saw one 20 years ago, and know the difference in the cap design. I just would like to add it to my references. A photo of its short range TP fuze, the VS-2 would be also appreciated. I have the manual drawing, but i've seen it only once during range clearance, and it was destroyed.
