Re: 20mm shell needs some power.
 

Have you not played the early versions of DC? You'd know what a huge splash damage can do.

Re: 20mm shell needs some power.
 

40mm dosent have 2x the charge as 20mm.

Charges are mass, not width. 30mm has around 4x as much charge and destructive power as 20mm, and 40mm has around 10x.

20mm isn't huge, but its enough for some small splash damage.

Re: 20mm shell needs some power.
 

Give a 20mm huge splash?

Why not give the 50 cal huge splash too,

A 20mm's alternate designation is .70 cal to put that in perspective.

Re: 20mm shell needs some power.
 

But 20mm rounds are actually HE, and your perspective means little, as .50 cal is 12.7mm bullets.

Re: 20mm shell needs some power.
 

Ive seen a real 20mm HE fired long ago. I recall it blasting a moderate amount of shrapnel 1-3m diameter, the area first few inches from the hit was heavily damaged by shrapnel. I think they should make a 20mm shell in FH hits a targer few inches away from a man, hes should be dead or atleast badly wounded. if the shell hits about a meter away i think he should be moderatly wounded.

I got some picture of 20mm damage on planes.

In pic A, a 20mm round from a German FW190 gave a direct hit on the ball turret of a B-17, the gunner was killed instantly (probably a internal explosion)

In pic B, a 20mm shell hit the faceplate of a ball turret and exploded, the gunner was badly wounded but survived. (external explosion, faceplate probably saved his life)

In pic C, a Japanese 20mm shell(s) hit on the plane (i dint get any more info on that pic)http://xs14.xs.to/pics/05055/20mmDamage.JPG

Re: 20mm shell needs some power.
 

The above is the way it should be done, some people seem to think a 20mm should blow you apart when it lands 10 or so feet away from you. You obviously won't be feeling to special but you'd likely live. Now something like the M203 would obviously kill at 5m as it has 10x or more bursting charge. I think that if the shell lands within a foot or so it should outright kill you, but past about a meter it should mess you up. It would give them a bit more 'umph' but would prevent pilots from just skimming over a base with 20mm and taking down people like crazy.

Re: 20mm shell needs some power.
 

I fired and trained with many weapons in the army. Firing a 20mm next to a target does sweet fa. I know because I shot it at a roo and it was only direct hits that seemed to make it care ;).

Re: 20mm shell needs some power.
 

check your math. 25.4mm * 0.70" = 17.8mm

20mm / 25.4 mm = 0.79"

40mm, 20mm, 12.7mm and 7.62mm

Re: 20mm shell needs some power.
 

Never said 20mm has 1/2 the charge of 40mm, not even close. Hence the suggested 1 to 2 meter 35% damage figure compared to the 40mm's 5 meter 100% damage figure......?

I personally lean towards a 1 meter 35% splash. This means in order to kill a person 3 20mm shells need to exploded within 1 meter of a person. This will not lead to "plane rape."

I would say a 3 meter 35% splash for 30mm too.

the 20mm apparently carried 10 times more explosives than what we've used in this thread: around 20 grams.
