I have some question about Dm63 

 i saw some test about dm63 hitting a infinite target and get 605mm of penetration, don't know if the information is right, and also the 675 penetration for 5 steel plate and have air gap between each other, maybe 150mm for each,and also i use the calculator, if the dm63 is 685(from wiki) 26 diameter it will need to have around 1800m/s to get 605mm 90° penetration, 237 for BHA,and if the dm63 is 730 long it will only need 1740m/s(speed for L55)to have 605mm of penetration, so i am very curious about the dm63 also the dm53 real penetration now,and also the penetration rheinmetall gave ,dm33 450-500 dm63 650-680 L44 720-750 L55 if use 510mm 26mm diameter 2km 1530m/s 90°, 200 BHA will get 481 mm performance, it is 450 <and <500.but if use 656mm long 1560m/s 2km 24 diameter dm63 will only get 600mm performance ,if use 730mm length will get 664mm performance which is 650<and <680.

But if you use 11.35×11.35×pi×656×1.72 is 4.6kg

I saw a picture about the weight and it is 4.6kg 

26 diameter 685 length English wiki

22.7 diameter 656 length russian wiki

Br i am very confused now

saw this on a Chinese website,they said 36 is a WC penetrater

Longrod calculator is not really useful tool for the penetration calculation of modern APFSDS. DM63 has not monolit but segmented penetraton. Furthermore, the longrod calculator cannot calculate with the significant improvement in the mechanical properties of heavy metal alloys.

Chinese DTC 10

If I understood correctly, the insinuation here is that DTC-10 (125) penetrator is about 590mm long?

Yes,but it have a short WC penetrater behind the main penetrater, and have steel cap .so probably around 635mm ,plus all of those. also the short wc penetrater is 90mm long, but half of it is inside the 590mm main penetrater plus it has smaller diameter

[jojoisgood]

Did anyone have the information of Dm63or dm53 penetration testing ?

Really want to know .
