BF-109e4 2x20mm Cannons

[Slade]

Hello,

The BF-109e4 has two 20mm cannons.  Combined do they have a faster firing rate than the single nose mounted cannon in the BF-109f?

For those that have used the BF-109e4 a lot, where have you found the best convergence setting?


Thanks,

Slade

I use them around 200, they are probably the worst cannons in the game. I imagine the volume of fire ends up being similar to the 109f but they're ballistics and stopping power are much worse.

The cannons on the A6M2, A6M3 and G4M1 are essentially the same cannon.  The cannons on the A6M5 and N1K2-J are upgraded versions of them.

From what I understand, the cannons on the A6M5 and N1k2-J are jam packed with HE(mini tators) rather than being purely kinetic like the MG/FF(50cal tators).

109E used a HE round for the 20mm, the  Minengeschoß.

[Charge]

The HE and Minengeschoss were different rounds for MG FF. The later MG FF model which could use the lighter Minengeschoss round was marked with a suffix MG FF/M. The MG FF usually had either a HE or Minengeschoss in their belting for aircombat so it was usually not a purely kinetic weapon like the .50Cal.

1 151/20 MG is far superior to 2 MG/FF.

I don't know if having 2 makes it have a higher rate of fire than the 151/20 but it doesn't matter because the MG/FF sucks! The only cannon in the game worse than it is the tater on the K4 and that's only because it's bugged all the uselessness.

The MG/FF does pitiful damage for a 20mm and has horrid ballistics. I set mine to 200 and I never use them outside of 200.

Enough with the 30mm. If you're not getting kills, you're simply an incompetent gunner. And I've fought you, I know that's not true.

Additionally, if we can see if there's a statistical drop in kills with the K4. If there was a recent bug with the 30mm, we would see exactly that.

As a matter of fact, I'm going to Snailman with this now.

Ok then - is the 20mm shells used in the Bf109E-4 explosive variant?

Yes.  All air-to-air 20mm cannons used in WWII were HE.

MG FF/M was introduced with the E3 and ran through the F1. If Hitech has chosen to model just the Mine shell, then 700m\sec. MG FF/M HE and AP rounds both shot at 585m\sec.

In the 109E versions wing mounted MG FF/M and MG17 were both set for the same 400m impact point. The MG FF/M were set to converge at 200m, while the MG17 were set to converge at 400m. This created a sweet spot at 200m.

I would think Hitech would have chosen 700m\sec for play abilities sake. Still you have to wonder how many players over the years have complained about gunnery in the E4 who were only hitting most of the time with the MG17 and no 20mm.

You can test this. Spawn on the runway. Bring up the target and set the range to 766 yards with an azimuth of about 10. Shoot only the 20mm and do a 1- Mississippi as you tap the trigger. If the rounds take much longer, then 585m\sec is your velocity for the 20mm. Not much better than the MK108 in that case.

[Mister Fork]

Then does Aces High emulate the 20mm HE ammo?

[PR3D4TOR]

If i remember correctly HTC has chosen to model all mixed belts as a hybrid round that combines the average effect of a burst of rounds. So the typical mixing of AP and HE/HE(M) rounds in german cannons is simplified so that every round is the same and incorporates the average penetration and explosive force.

[bustr]

I tested the MG FF.

Time to target at (700m) 766 yards: One thousand, Two Th..splat!!

A 700m\sec round would have hit at "One Thousand" splatt!!

Yup, 585m\sec rounds.

Effective combat range is 200 yards. Convergence is 200 yards. Only fire the MG FF so you are not fooled by the faster MG17 7mm rounds into thinking you are doing any damage. Think like you are shooting with ballistics just a smidgen better than a MK108.

Now you need to think about the FW 190 A5 and what those wing mounted MG FF were added on to shoot at. (Slow level, Bombers)

From the big book of Luft ammo the MG151/20 ammo has two primary velocities.
HE\Derivatives 705m\sec 
M-Geschoss 785m\sec.

So if Hitech is combining all of this, he would pick one or average both: 745m\sec

FW 190 A5

MG FF ------ 585m\sec
MG151/20 - 745m\sec

MG17 ---- 745-905m\sec <<---depending on type of round. I've never seen anything published from HTC on this info.

Now we have the same problem as the E4. Which guns are you really tagging your con with?

[Rich46yo]

I always thought the 151/20 MG was like a "super cannon" when compared to other single nose cannoned fighters.

Please explain to me which are the best cannons in the game and why? Thanks.
