some might know that we have practice rounds in game, which are sometimes included in aircraft’s ammo belts.
For me the japanese 30mms are the most interesting ones (Ho-155 & Type 5).
Some time ago Gajin switched the pen values of aircraft cannons into the “de marre” formular to a have a unified system.
AFAIK the practise rounds weren’t touched by this change Preformatted textas the pen values remained the same as they always were. (23mm pen at 0m, 0°)
Now I’m wondering: Is the 23mm pen value accurate?
Muzzle velocity: 920m/sec
Explosive filler: 0.00g
With Gajin’s calculator
https://wiki.warthunder.ru/New_formuls_for_calculating_of_the_armour_piercing I’m getting 52.66mm of pen for an AP round.
From what I understand practise rounds are just worse AP rounds, but what would an accurate multiplier be to calculate the pen for them? Any idea?
