...

Some sources say 200, others say 150..

AH G-2 has 150..

which is right?

200 rounds is the correct number for G-1 and G-2 (same as F-4). The bigger main wheels introduced in G-4 and G-3 made necessary the adoption of smaller ammo boxes with 150 rounds.

I am not debating the answer..but the reason seems suspect. The wheels of the 109 retract away from the fuselage where the ammo for the engine mounted 20mm is stored.. How could the size of them main wheels effect the capacity of the cannon magazine? Ill have to look at a few cut aways when I get home..

True, the wheels pull up away from the fuselage, can it be some kind of new mechanism for the wheels that makes them take more place?

Ammunition box of the engine mounted cannon of the Bf 109G was in the wing.

um...

I don't think I've heard a answer yet.

What interests me is the part that goes:

"200 rounds is the correct number for G-1 and G-2 (same as F-4)"

..

In the case of that other game

'IL-2', the G-2 and F-2 has
200 rounds of 20mm in the game.

Which is right? 150 or 200??

Both the F-4 and G-2 in AH have 150 rounds...

my cut away of a G14 shows the engine mounted cannon magazine to be right behind the engine above the cannon.
My cut away of the G10 shows the same thing.
I dont think the ammo was stored in the wings.

The ammo was stored in a box placed in the left wingroot. This from the original weapon operating instruction manual (1942). I'm pretty sure that someone scanned it and posted it somewhere in the net.

Other documents from 1942/43/44 also say 200 rounds.

A data sheet about F-4 (November 1941, IIRC) also indicates 200 "schuss" (rounds) for MG 151/20.

Hope this helps.

I have also seen 200 rounds as the ammo load for Bf109 20mm engine cannon often.

HTC can we have our 200 rounds please?

Pongo · « **Reply #10 on:** February 02, 2002, 04:26:16 PM »

hmmm
Do you have a simular diagram for a G series?
Cause that must be the difference. The drum on the later Gs probably only holds 150. It is right behind the engine in the diagrams I have.

Planes of Fame says that the earlier Fs with the 15mm mg151/15 had 200 rounds. They say the F4 with 151/20 droped to 150 rounds...

Pongo,
Well, also I have diagrams which show magazine in the fuselage behind engine (like one in the "Wings of the Luftwaffe") and other similar BS. But I have also seen original manual and even checked real thing; magazine is in the wing just like Porta's picture shows.

Anyway I don't know for sure it's capacity; should 140-150 in the G-6.

GRUNHERZ · « **Reply #12 on:** February 02, 2002, 09:54:23 PM »

The diagram shows at least a Bf109G6, those are Mg131 cowl guns.

The other magazine location you reffer to Pongo is where the Mk108 30mm ammo storage is. It was moved into the fuselage.

All 20mm Bf109 engine cannon were fed from that wing box.

It should have 200 rounds instead of 150.

Soooo... does this mean we'll be getting 50 more rounds of 20mms in F-4s and G-2s anytime sooon ???

Make HTC aware of this issue and let's behave, so they don't get annoyed

That should help
