Title: Lancaster tail gun ammo ammount seems odd
Post by: Karnak on April 02, 2003, 01:37:59 AM
The Lancasters equipped with the Frazer-Nash tail turret (four .303s) carried 10,000 rounds of ammo for the tail turret (2,500 per gun).

Why does the twin .50 cal turret in AH only have 670 rounds?  I know the .50 cal rounds are larger, but they're not that much larger.

I'd guess that 4,000 (2,000 per gun)  rounds would be a more likely number than 670 rounds. (335 per gun).  335 per gun seems like a very unlikely small belt for the position that was considered most important in WWII (that's why the tail guns were the first to switch to the .50s).

Does anybody have an explanation for this?

I'd also like to know why the 109G-2 still only has 150 rounds.

 If I recall, eiher the Typhoon or the Tempest also has incorrect ammo load..

The Rose Brothers company of Gainsborough developed a rear turret that was much roomier than the FN types and came equipped with two 12.7 mm (0.50 in) Browning machine-guns. The new Rose-Rice turret had 335 rounds per gun and used a Barr & Stroud Mk IIIA reflector sight with a traverse of +/- 94 degrees, elevation 49 degrees and a depression of 59 degrees and allowed for a total firing time of 24 seconds (compare that against the 130 seconds firing time for the four-gun turret). The Rose-Rice turret was only used by Nos. 83, 101, 153 and 170 Squadrons of No. 1 Bomber Group from the middle of 1944 onwards. Frazer-Nash later developed the F.N.82 turret which was also fitted with twin 12.7 mm (0.50 in) Browning machine-guns and equipped the Lancaster Mk VII.

The .303 round is HALF as tall as the .50 caliber round, and the .50 cal round carries roughly 1100 to 1300 grains of powder where as the .303 carries approxiamately 180 - 240 grains of powder.   That means the powder is apromimately 5 times as much as in a .303 round.  Lastly the actual projectile size is MAJORLY different.  If someone can provide me with web space, I will post pictures of the projectile and the rounds different sizes.  Plus a comparison of the casings and powder amounts.

Bodhi,

Yes, I know the .50 is bigger, but at 4,000 rounds that's still less than one round of .50 for every two rounds of .303.  670 rounds simply seems ludicrious I doubt the .50 cal round is more than ten times the size of the .303 round.  But Dr Zhivago's info says it is correct.

It just seems very odd to me.

Karnak,

The solution to your problem is probably more obvious that you think.

Unlike AH the gunner would more than likely just "reload" the gun.

Their is nothing to say that they didn't carry an extra box of .50 cal.

How many rounds do the jeep mounted M2 .50cals carry in those ammo boxes? I bet that thing carries at least 100rounds. How many of those could you fit in a Lanc??

ammo amounts seem a bit weird because if they had there real ammo amounts the planes would be a lot better...though it would be nice in a lanc...and would you really want those "temp dweebs" having even more ammo???

The idea ammo would be for the plane and not by the gun for a bomber since ammo could be passed between gun positions as needed.  so if each gun had 2000 rounds and the buff had 10 guns then total ammo would be 20,000 rounds

The .50 ammo weighed nearly five times as much per round as the .303 - and weight was an issue.

It was discovered that the 10,000 .303 rounds was excessive and never required. Operational Research calculated that 2,000 rounds would suffice for 99% of missions.

Ummm, geeee, 1200 grains, vs. 200 grains, so we need repetition???????

(Yes, I know a grain is a weight of powder, I quoted it to begin with!  1100 - 1300 for a .50 cal, 180 - 240 for a .303.  Umm, the projectile is almost 10 to 1 in weight... scary huh!

The .50 cal bullets weighed about four times as much as the .303's (it varied depending on the loading).

the .50cal ammo cans hold 50 rounds, or at least the ones it left the factory in linked

I thought the .50 cans held 100 rounds?

Tempest

Missing 50 rounds per gun, should be 200 rpg, so we're missing 200 rounds :(

That's simply NOT TRUE... I have over 150 Ammo Cans WW2 ERA filled with 100 Rnds each, LINKED .50 Caliber (the ammunition are dummys for our museum).  Guess the workers were taking the extra 50 rounds home in your factory?!?!

AFAIK there never was over 150 rounds in a 109. In fact Finns used only 120 or so rounds because the cannon was prone to jamming with full ammo.

Ummm...yeah...ok.  HTC just arbitrarily puts a number in with no research to back it up.  Just so the planes dont get too good.

:rolleyes:

Well that could be true on a B-17 or a B-26, but our Lanc has .303s in all other turrets except for the tail gun which has .50 cals.  You cant very well pass ammo around to a different gun if the ammo wont fit.

A .50 can fire .30 ammo, I just REALLY wouldn't recommend it :)

I bet you'd have more chance of hitting your own plane than the enemy

Maybe the .50 held less ammo cause there where not only exploding, but also fire trail bullets, they indicate the way you're shooting. but they didn't have any powder I think.

The US never used HE bullets in the .50 - only incendiary, AP or API.

bodi, lighten up i was talking about the ones ive seen and carried. i wasnt around in ww2 so im not sure EXACTLY what was around then. your post is a prime example of why people dont like to post on the BBS. you just could have pointed out my mistake without being a total prettythanghole. but theres alot of that on the BBS. i dont blame you, manners and home training seems to be highly perked these days.

kdavis it wasnt you that my reply was aimed at but bodhi. from what ive seen of this guys posts on a lot of topics he just likes to to slam people. maybe he got a big stick up his butt when he bent down to change the tires on his house. but who knows he could be one of those high strung inbreads. or both. i reload myself and know that you need to be correct on powder weights if you like your face. my fav rifle is my winchester mod.70 .300 win mag, its never had a factory shell in it, unless at the factory. but that is an easy one. i give them all the shake test 2-3 times before they go in the box. since i dont do compresed loads with slow burn powder there is just enough airspace to shake and make shure there is powder in them that to me is the biggest mistake in reloding you can make. if you fail to put powder in the shell when you fire it, the primer will send the bullet halfway down the barrel and on the next shot trouble begins.
