Thank You ^^
OK for 20mmAP ammo and T34 ^^
You got the key: standard round. I don't know, but maybe the "DP" machinegun mounted on soviets armored cars have mixed ammo? AP, incendiary, ect?
small stories:
I made an experiment a the range, one day...
I have a K98k, and about 5-6 reloaded 8x57ammo with old piercing bullet. (old WW2 ammo "from the wood" a bit rusted you can find in France ^^ We usually take away the case, primer and powder, re-use only the bullet. But I know some folks that re-use the powder too "they a 2 sort of german powder" they say. I prefer not trying ^^)
at 100m, on a 30mm thick plate at 90° ( "creusabro" steel: best quality) they make a crater about 5mm width and you can see the "penetrator", a small hard stell stick, stuck in the middle oh this crater.
I paint again the plate and continue firing "standard" ammo. And surprise! An lucky bullet hit the same crater a previous penetrator was stuch and... push it right trough! I have a small hole, ~4mm from side to side of my 30mm plate.
Oh! and another day:
- cops: "Hello! We have receiving our new armor plate for our cars. Can you give it a try on this one?"
- We: "Yes! (chic-chic!)" place the plate at the 100m range.
* .22lr: some paint is gone. Maybe.
* .308? (I don't remember): a small dent
* .300winchester magnum: Oh! that's a big dent!
- We: Ok, next step, AP ammo!
- Cops: Hehe, no thanks, that's all we have to know, standard ammo won't penetrate, it's OK.
- We: Oooooooh (disapointed)
