before i start no this isnt classifed it has been made in early 2000’s [estimated could be older or newer] translations might be inaccurate so if someone thats chinese would be able to translate or fix mistakes would be nice[not the full thing but what matters]
translation: The introduction of this article states that Project 123 is a tungsten alloy ammunition that can penetrate 600mm of homogeneous steel at a distance of 2km under normal temperature conditions.
The overall parameters of the armor-piercing projectile: projectile mass 8.12kg, bullet length 680mm, projectile core diameter 22mm, flying object mass 4.59kg, flying object aspect ratio 30.9, penetrating object aspect ratio 29.5, tungsten alloy rod length 650mm, tungsten alloy rod mass 4.44kg , tail fin mass 0.15kg, tail fin length 100mm, tail fin sweep angle 70°
The article also mentioned a plan to increase the propellant cartridge and increase the amount of propellant to 9.2kg. The Project 123 using the new propellant is expected to reach a muzzle velocity above 1800m/s, thus penetrate 700mm of homogeneous steel at 2000m

now i dont imagine dct10-125 should have 680- 700mm of penn in the game as thats horrendously overpowered i would imagine around 625 or 635 mm of penn [up to the devs but atleast over 610 and for wz1001 maybe 646 now this change may have to have alot of br changes for vehicles unless tanks like mbt2000 or ztz99-ii and iii to just leave it as i believe they are already good enough with 575mm of penetration and will have a hard time with br changes. this also tells the correct penetration of type 1985-I apfsds [referred to 125-I] as one of the files state 460mm at 2000m as ingame its 465 and loses 32mm of penetration at 2000m [434] so if my guess is correct its around 497mm of penn [508 on wz1001e]
