krusty- 200-400 yards is too far for the 30mm, you really need to get below the 200 mark.

from my experience a single 30mm will kill. only time he doesnt kill a fighter in 1 shot is when he hits the engine. (which sounds reasonable), 30mm takes alot of patience and can be very frustrating, especially in deflection shots.

urchin, tracers are not to be trusted, not every round that goes out is a tracer, and you cant really call which round is which.

So far in AH2 the best 30mm kill I had was 800 yards, but 200-400 is reasonable.

Urchin you know it was a mistake to fire the 13mm with the 30mm - because of that I cant say the video proves anything. And thats a shame cuz I also think the 30mm isn't quite correct in hit power.

Got film of another engne kill. Apparently I'm getting lucky (or unlucky, since I'm trying to get a hit on someone and not get an engine kill). I'm filming all my 30mm sorties, I'm sure I'll get what I'm looking for shortly.

Yea, I know I screwed up hitting the MGs, finger slipped tho, not much I could do about it.

Do the test I did. Stopped at runaway in a 109G10 and then firing round by round with max zoom. Look at the random dispersion applied as soon as you shot the round and stop wondering why you miss every shot.

yes Urchin, succumb to the dark side of pessimism! It's no use resisting!

Sorry to deviate ,but I gotta know how Timrus takes a pic from the film?

Tim how do u take a pic from the film?

IMHO 30mm's are a waste of time. Too few rounds and velocity (if they're modelled correctly) is low...WAY low. We're talking blackpowder rifle cartridge velocities here; around 1800 fps. As a comparison, the .50 cal runs in the 2800-2900 range as does the American .30 cals. When I have had success with the 30mm, it's been at very close range. Personally, i can find no use for it unless of course I'm flying one of the jets.

I'll take a 109 armed with a 30mm in the engine and you take one armed with a 50cal engine gun instead. Lets go hunt bombers or play with angry P47s.. OK?

1. Open film viewer and some graphics editing program ( I use Microsoft Photo Editor).
2. You can run the film in slow motion and even freeze it, pan , rotate, jump into other plane etc. When you have the frame you want, press alt-print scrn. It copies the image of the active window into the clipboard.
3. In photo editor: Edit-Paste pic from clipboard, then you can select the portion of the pic that you want to show. Save that as new picture.

I flew the G-10 a lot for a few months, improved my gunnery no end. But I only managed to hit anything at 800 in AH1 with 0.50's at a target flying straight and level. The same with the 30mm in AH2? Never. How do you do it?

Noticed that convergence settings are a lot more important now (at least so it seems to me). Not much problems adapting but I tend to open fire at much closer ranges. Had two one ping kills with the 30mm so far, including a crossing shot point blank on a P-47. Will have to try it a bit more to get a feel for it again.

It might've been V-sync after all, I dunno. Been flying the G-6,G-10, and 262.. so far every ping has resulted in a dead engine or a dead plane. I changed Vsync from (I think) default on to always on.

Why does the 30mm have such a large dispersion pattern? AFAIK it should be rather small due to low muzzle velocity and heavy grenade and low ROF.

A gun with high ROF, high muzzle velocity and light bullet/grenade should have a rather large dispersion pattern?

Maybe Mr. Williams could confirm this?

I used to like the 30mm in AH1 but in AH2 I feels very inaccurate.

Maybe the low velocity doesn't allow for a high rate of spin when fired. Maybe less twist in barrell.?

Krusty · « **Reply #28 on:** August 30, 2004, 10:41:48 AM »

Historically pilots complained of the bad trajectory of heavy cannon rounds (30mm +). They never complained of inaccuracy. So our 30mm drops like a stone, fine. But it sprays out in a random cone about 3-4 times the size of a 20mm dispersion (not a measurement, just an estimate).

I think that's just adding insult to injury, if it's true.

I far as I tested, the random cone seems similar to 20mm, in any case, IMO there is not explanation for that dispersion firing round by round with the aircraft stopped.
