Had a discussion with some other fellow P38 enthusiats last night concerning the ammo load and weight of the same. I did a search on all the back threads, but I didn't see any hard data concerning the 200 rounds per gun, compared to the 500 rounds per gun. To sum up;
1. On personal preference, what do you fly with? The light or the heavier ammo load?
2. More importantly, does anyone have any hard data regarding the difference betwwn the two?
----
1. Personal prefence for me, I figure the ammo load is in front of the center of gravity and is much lessened than it would be in the wings along the center of gravity. Yes, there is an effect but very minor.
2. I have no hard data, unfortunately.
Thanks in advance, P38 sticks :)

I always fly with full ammo load because I usually don't have a problem moving it around anymore, but I know if you choose small ammo load, you will feel a small difference, it just seems more responsive to me.
-
I'm still upset over the lack of 2k eggs being available to the weapon loadout.
-
I always fly with 200 rounds per gun if I'm upping as a fighter. 1200 extra .50 cal rounds adds a few hundred extra pounds, and it's noticable. Plus, as long as you're a decent shot, 800 .50 cal and 150 20 mm is enough to score 8-10 kills in a sortie, especially if you reserve your MG ammo until your cannon is out.
On the other hand, if you're on a jabo mission, 2000 MG rounds is handy for strafing.
-
I always use the full ammo load out. More lead to put into the air is a good thing. I've also never noticed any appreciative advantage in having the lower ammo load, whatever improvement it gives to maneuverabilty is hardly, if at all, noticable.
I've also asked 3 former P-38 pilots this same question and they all said they would always take a full ammo load. Not one of them could remember gaining any type of maneuvering advantage from taking a lighter ammo load.

i load my p38 always to the fullest.
And fight according to my weight.
-
what is the actual weight of 1200 .50cal rounds?
-
2,000 rounds of .50 cals. 500 rounds each .50 cal.

With all the ammunition we go through in a given mission - all of that add's up to a $$ amount. Lets take a normally equipped P-38L with 2000 rds of 50 cal and 150 rds of 20mm. According to this matrix which is several years old....
50 cal API is $2.03 x 2000 = $4,060.00
20mm PGU-28 if you could is it $16.91 x 150 = $2,536.00
If you throw two 500 lb bombs into the mix, the MK-82 is the closest bet: 2 x $1,706.97 = $3,413.94
Fuel: 418 gallons 100 octane @ $2.80 / gallon (National avg pretty much): $1,170.40
So a typical combat loadout comes to: $11,180.34
Not included are hourly operating costs, maintence, engine replacement fund, insurance, cost for training, sexing and paying off your maintence chief who will make you **** the bullets he must take from your airframe. Thought you guys should know
Best,
Wolf

Take full load always. If you think the plane would fly better for you with less ammo, feel free to pump 1000 rounds into your first target.
-
light load for me always
-
always light load here as well.

Heavy load thats 5 more kills.
P38s could carry torps?
FA says so.

There were some tests on a G model that was equipped to drop them but don't think anything ever got beyond the testing stage.

If you can fly it, you'll load the full loadout because the small runs out too fast. Even if your a good shot, your still going to take longer to kill, to get in close range, and get less ammo to shoot.
The the advantage to kills to weight is leaning to heavy to the kills for me, not worth going light IMO. :D
-
2000 rounds of belted .50 ammo weighs 622 lbs. So you can save 373 lbs by using the reduced ammo load (about equivalent to reducing fuel load by 15%). This is on a 17,000 lb airplane mind you. The extra ammo seems well worth the weight to me.

if you can land double digit runs with small ammo load, whats the point? i like the less weight, to each their own.
~S~

Great discussion, tho it looks like Hooligan is the only one with anything close to hard data.
Anyone else have anything?
-
Not too historical here, just know how to fly the thing in this game. Too lazy to look up charts and data. :D

If you were to fly a light ammo load P-38L and then a heavy ammo load P-38L, you will be very hard pressed to notice any appreciable advantages in carrying the light load.
And if a light ammo load did give you a significant maneuverabilty or performance increase, why did the vast majority of the P-38 pilots take the full ammo load? Probably because it really didn't make all that much of a difference in performance.

always light ammo and i notice the difference

I can't hit the broad side of a barn anyway, so the more ammo the better :)
From a historical standpoint, I don't know that I've ever heard of a real 38 driver going out with less ammo when he could carry more.
One of the redesigns from the 38D to the E model was changing the nose gear so that they could get more ammo in the nose.
For most the 38 was a B & Z plane in reality not a turn and burn bird. Only the best of the best would stay in and turn and that was only as the last resort.
Torps tested but not used operationally. I've seen photos of 1st FG 38s that carried 3 500 pounders under one wing, two 500 pounders and a drop tank under the other. Clearly there were lots of in the field mods that allowed them to carry more then they came from the factory ready to carry.

Since I like photos to go with the conversation. Nothing to do with 38 ammo in the nose, but stuff that came up in the thread
Dan/Slack
The initial model 322-60-04 Lightning(Only turbosupercharged Lightning to carry RAF Markings. Essentially a P38F-13-LO) It was loaned by the USAAF to Lockheed and was tested with two torpedos
(http://www.onpoi.net/ah/pics/users/ah_169_1076357156.jpg)
82nd FG P38L, 15th AF loaded out with 2 drop tanks and 4 500 pounders
(http://www.onpoi.net/ah/pics/users/ah_169_1076357189.jpg)
1st FG P38L, 15th AF loaded out with 5 500 pounders and 1 drop tank
(http://www.onpoi.net/ah/pics/users/ah_169_1076357216.jpg)
82nd FG P38L "Droop Snoot", 15th AF with 6 500 pounders
(http://www.onpoi.net/ah/pics/users/ah_169_1076357239.jpg)
And a landing P38F cause I love the image and those early, small intake 38s :)

You wouldn't have any pictures of the P-38L "Super Strafer" outfitted with 8 .50 caliber machine guns in the nose and two more mounted in pod under the wings? That's one weapons package I wouldn't mind seeing on the P-38 in AH

Never heard of that one Ack-Ack. Was it a field mod or something tested by Lockheed? I have enough 38 books floating around, I'm surprised I haven't run across it.

It was supposedly an after war modification they did to a P-38L. They doubled the .50s in the nose to 8 and added gun pods under the wings with 2 more .50 cals per gun pod. Don't know if is a USAAF test or Lockheed's but obviously nothing ever came out of it.
This is the site where I saw it was mentioned. They also talk about another P-38 that was modified with 3 .60 caliber machine guns.

good read ack ack. be kinda fun shooting something with 4x37mm too. :) all in the nose nonetheless, what a punch.

I don't really see the point of taking less than full, unless you intend to jump right into a turnfight on the deck. Even if I am a bit heavier, I'll tend to burn off the excess .50 rounds before I get into a position where ammo weight might be a significant factor...
