Re: 20mm shell needs some power.

Keep in mind that "20mm" was not a standard throughout all countries in the war. There are Japanese 20mms (very effective) and Brittish 20mm, U.S. 20mm, Russian 20mm, German 20mm. Each one has a varying size and muzzle velocity and effectiveness.

The variances increased even more as sizes went up. Bofors 40mm was a lot more powerful then 2pdrs (larger shells, MUCH higher muzzle velocity).

I don't think we'd need to code anything so complicated in FH, but we should have small, small amounts of splash damage for 20mm and about 1/3 the deadliness of a hand grenade for 30mm.

Re: 20mm shell needs some power.

would just like to specify that the number above is for the german 20mm 92g M-Geschoss. image included in this post has been open in my browser for the past three hours. , and shows exactly what you mention. the interesting ones are (from left) #3, #4, #6, #7, #8, #9

another observation i made - the 30mm (german auto-cannon) has far more powder in it, than behind it!

A comparison photo of the ammunition used in the Battle* with some other rounds is HERE: from left to right, the .303 British (7.7x56R), .5 inch Vickers (12.7x81), .50 Browning (12.7x99), 20mm Hispano (20x110), 7.92mm v-Munition (7.92x57), 20mm MG-FFM (20x80RB), 15mm MG 151 (15x96), 20mm MG 151/20 (20x82), 13mm MG 131 (13x64B)

*Battle of Britain

Same medical report
out of 50 casualties wounded or killed by either 20, 13 or 7.92mm fire (german) 37 were wounded by 20mm and 7 killed. wounded and killed combined from 13 and 8mm was 6.

there are also pictures of fragments from 13mm HE taken from fatal wounds.

i would suggest looking through those reports. it helps you put various threats to air crew into perspective, what some of them went through, and so on. but at the same time i would have to warn you that this is a medical report - not all of the pictures are completely safe.

Totally depends on what ammunition. A Minengeschoss round has ~18g PETN.

It should be like the 88 and 40mm shell, it should wipe infy off the map, and be a great house clearer. Also, the same should be fixed on the 20mm AA, plus the 20mm AA should have that proximity expolsion too, as they did use proximity fuses on the ground 20mms.

No? The germans never had proximity fuses for 20mm AA guns in WW2 according to my sources. And those same sources say that 20mm rarely had proximity or timed fuses until just recently in 2000 with the development of the OICW. Its much too small a round to warrant an expensive system like that.
But I ENTIRELY agree that 20mm needs SPLASH DAMAGE and I've been griping about it for several patches. What's the point of 20mm if it dosen't have splash damage? The point OF 20mm was to have explosives in a rapid-fire cannon. 30mm MK109/MK103 needs it too, as well as 25mm Hotchkiss guns (Japan AA). The Vierling should be a horror.
Just bumping this.

Harmann, you know as well as I that these weapons had a radius of lethality just like any other explosive. It may have been small, but in the case of 25mm-30mm, it got a lot larger. Giving these weapons NO splash damage is completely removing the point of them. It is realistic and called for to give 20mm some splash damage. That's what it was, was a teensy explosive. For it to not explode is silly. 30mm should have a considerable radius, not necessarily lethal, but damaging.

Re: 20mm shell needs some power.

Ironically it seems most 20mm used in WW2 were originally based on the Oerliken design.
