or in the case of the higher dash number Me109 the FF cannon that didn't work so they had to redesign it to the FF/M that did with limited drum feed that couldn't use mixed ammunition.
No, for a start each .303 was good for around 1150-1200 RPM where's the .50 cal was if we are being honest good for about 450 RPM
I read your posts. I remembered.We have been over the 1930s .50 cal stuff a bunch of times.
The US .50 from the 1920s to about 1940 was NOT the gun used in 1942, either the gun or the ammo.
I`d like to know why the WW2 Rolls-Royce aircraft cannon project floundered.
The FF cannon didn't work that's why they redesigned it into the FF/Modified, the ammunition isn't interchangeable between the guns. As for the .50 Cal the rate of fire was 450 rounds per minute, the ammunition was low velocity and they weren't reliable, like the FF they were found lacking in combat so once again both the guns and ammunition were modified/redesigned into what became the M2 variant, what part of any of that is misleading?.(my bold)
Having personal favorites is okay.
Throwing mud on what you don't like in order to make your favorite stuff is misleading.
Yes, yes it did Grasshopper.Please tell me that one had punctuation!

Please go and see for yourself and see what you think however before you jump there and start reading you might want to prepare yourself by reading say episode 18 of the literature classic James Joyce Ulysses see here for a link Ulysses by James Joyce: Episode 18 - Penelope that shows that punctuation is overrated anyway and is only a crutch used by lightweights good luck and have fun although one can of course debate the literary quality of a 9 page long internet forum thread about aircraft guns versus what is ostensibly a shining example of modernist literature but that's up to the reader to decide it's all relative anyway as James Joyce himself might have very well been aware as Einstein had published the general theory of relativity in 1915 a few years before Ulysses was published so relativity was on everybody's mind back then as it was a big change in how people thought about mankind's place in the universe and everything.
M is for 'this version fires Mine shells', not for 'modified'. Mine shells were judged as better ones, and the FF/M was tweaked to fire the better ones.The FF cannon didn't work that's why they redesigned it into the FF/Modified, the ammunition isn't interchangeable between the guns.
Nobody found the FF as lacking in combat, these downed hundreds and hundreds of aircraft.As for the .50 Cal the rate of fire was 450 rounds per minute, the ammunition was low velocity and they weren't reliable, like the FF they were found lacking in combat so once again both the guns and ammunition were modified/redesigned into what became the M2 variant,
Joyce was an overhyped booze-raddled blarney-merchant, who produced unreadable blather, mistaken by acolytes for a novelistic pioneer.Please go and see for yourself and see what you think however before you jump there and start reading you might want to prepare yourself by reading say episode 18 of the literature classic James Joyce Ulysses see here for a link Ulysses by James Joyce: Episode 18 - Penelope that shows that punctuation is overrated anyway and is only a crutch used by lightweights good luck and have fun although one can of course debate the literary quality of a 9 page long internet forum thread about aircraft guns versus what is ostensibly a shining example of modernist literature but that's up to the reader to decide it's all relative anyway as James Joyce himself might have very well been aware as Einstein had published the general theory of relativity in 1915 a few years before Ulysses was published so relativity was on everybody's mind back then as it was a big change in how people thought about mankind's place in the universe and everything.
When you take a blowback weapon and change the bullet weight significantly they don't work.The FF cannon didn't work that's why they redesigned it into the FF/Modified, the ammunition isn't interchangeable between the guns.
As as been stated other places, the .50 would fire at 600rpm when unsynchronized. The Velocity was about the same as both the British .5, The British .303, the Italian/Japanese 12.7mm, the later German 13mm, and it was only about 40-50m/s slower than the French, Italian, Japanese navy 13mm ammo. Reliability in aircraft did take some work.As for the .50 Cal the rate of fire was 450 rounds per minute, the ammunition was low velocity and they weren't reliable,
The work was going on before they were used in combat. The work on the ammo had been going for period of time, just like the change from the old .30-06 ammo to the new M2 .30 cal ammo. The new M2 ball fired a similar bullet to the old 1906 load but did it at 42,000pis instead of 50,000psi with the new powder.like the FF they were found lacking in combat so once again both the guns and ammunition were modified/redesigned into what became the M2 variant,
You can argue all you want but the guns were modified, you either fired one type of ammunition or the other, they were not interchangeable. Also if the original guns were satisfactory they wouldn't have needed ''better ones'' would they and then be replaced by the MG 151 on all 109 models thereafter.M is for 'this version fires Mine shells', not for 'modified'. Mine shells were judged as better ones, and the FF/M was tweaked to fire the better ones.
I'm talking about the M2 browning not a Breda or Vickers. In 1939-40 the RAF wouldn't have had the M2 model because it wasn't available, only the original model and original lower velocity ammunition.There was no Breda SAFAT M2, nor it was the Vickers M2. Both were firing much faster than 450 rd/min, and the MV was more than useful for air combat.
None of the newer guns and ammunition were available in 1940 except the FF FF/M and even then just under half the 109's that fought in the BoB were low dash Emils with four 8mm MG's. The question is why the RAF didn't use heavy MG's in their aircraft, the simple reason is oth the .50 BMG and Hispano needed an equal amount of work so why choose the smaller gun.The work was going on before they were used in combat. The work on the ammo had been going for period of time, just like the change from the old .30-06 ammo to the new M2 .30 cal ammo.

Work on the rate of fire was going on in 1940, very few of the US supplied aircraft had gotten into combat in 1940. Not the Tomahawks, not the P-39s, not the Buffaloes (at least in British hands).

Not the case, the .50 was passed over because it needed just as much development as the Hispano while offering lower performance, sorry but that's a fact.I was replying on what you've actually wrote, not what you've thought you wrote.
Which 50 cal? In 1940 it wasnt what it became in 1943/4. They cause different damage. In 1940 RAF pilots were being struck and damaged by single rounds from 20mm cannon while seeing German bombers sail through hundreds of hits by their 0.303 mgs. Post war it was found that although many bombers didnt go down straight away, they ditched or made forced landings with dead or injured crews, by mid September 1940 what was th most formidable airforce in the world was down to its last 200 serviceable bombers and crews.So basically the torrent of .303 slugs from 8 guns could do about the same damage as two 50 cal?
