This is not normal... or is it?

The Minengeschoss projectiles were the same, with the same amount of filler.

As far as I know Minengeschoss are not represented in AH.

As far as I know Minengeschoss are not represented in AH.

I know that AH belts are somewhat of an 'average, but for a), the MK 108 belt consisted mainly of Minengeschoss rounds (and as far as I know the MK 103 belts too, when used for air to air), and b) the Mk 108 and Mk 103 basically fired the same shells (just that the 108 didn't use the 101/103 armour piercing shells used for air to ground combat)



3cm mine / incendiary shell for Mk 103 and 108, as per title.

So I would like to know where the "3 times the filler" comes from. So far I didn't find anything

It was from a Swedish article that have been translated from a German source, it could have been an error, or they compared something else with the rounds, and velocity.

Since I flew mostly FW190a8 when I was active in AH, me and squaddie Torquila (him flying almost only the bf410), we compared notes killing bombers, and the 'average' power you wrote was quite big what it took to down a B17 and specially the B26, when I flew the BF410 I noticed the same thing.

I suspect AH add kinetic energy to the mix

The increased length of the 30x184B results from the casing alone, its the same projectile.

The kinetic energy is indeed about 3 times higher at the muzzle.

The other important factor in the higher velocity is the barrel lengths. The MK108 has a very short barrel as a trade off for a high(er) rate of fire. Otherwise, there would be too much pressure in the breach and cases would explode when the action opens - jamming the weapon. The MK103 has a slower rate of fire with the benefit of allowing for a cartridge with more propellant and a longer barrel for better accuracy.

So I went to determine the Mk 103 in game damage by the good old "rounds to kill hangar" method - the only way we have to assess damage done. While we only can fire the MG 151/20 and the MK 103 in unison, the ROF of both weapons are known and so is the MG 151/20's damage value (3.55). According to my findings, the MK-103 has a damage value of about 12.3, which is only a tad over the Mk-108's 11.6. Maybe someone else can do his own tests to verify this (or to find the error in my thinking)

That is cool. I don't think I ever got that one in all my years.

Next the CMOH like the one you could get in F19 Stealth Fighter!

Thanks fellas!

You start firing at longer range in the mk103 (the HO scenario), its ls so lethal in its nose mounted configuration, nothing survives.

Against B26 I normally got one kill and 1 or 2 smoking planes in the A8 with 30mms, against the B17 normally 2 kills and one smoking (2 or 10 o'clock slightly higher).
In the Me410  normally you start shooting at longer range, normally I got all 3 B17's and vs the B26 i got 2 and one smoking.

Note I did not count bullets, often the ME410 was messed up enough so you had to land , whereas the A8 was almost untouched, except when a certain 99000 was flying it 

In the A8 with 4 cannons you could expect less unless you shot from 11 or 1 o'clock, then you get all 3, B17s and in return you had a smoking or dead engine.
