Britain began the process of replacing its Vickers aircraft machine guns with a new Colt/Browning design in 1935, with its adoption of the Colt MG40. This was essentially John Browning's air cooled M1919 machine gun made smaller and lighter, with an increased rate of fire, and reversible feed direction. British adoption began with the purchase of 60 guns and a license for domestic production. This production took a few years to get rolling (by both the Vickers company and BSA), and in the meantime an addition 1600 examples were procured form Colt - including this example, dated 1937.
A few changes were made to the British pattern of the MG40. Most significantly, the clockwork was redesigned to run form an open bolt. This was deemed necessary because British cordite-loaded .303 ammunition was more sensitive to cookoff than American powders, and it would also detonate catastrophically upon cooking off. Unfortunately, this particular example has American ANM2 clockwork, so I can't demonstrate that change here. In addition, the British developed their own muzzle devices. The initial pattern suffered badly from powder fouling, and the replacement pattern consisted of the booster seen on this example plus an option separate flash hider cone. It was primarily the changes in muzzle devices that prompted the change of designation from Browning Mk I to Mki*, MKII, and ultimate MkII*. In total, more than half a million of these guns were made during World War Two, forming the primarily armament for the RAF (including Spitfires, Hurricanes, and Lancasters).

For the first time I hear someone knowledgeable explain "cook-off" properly. Most people just assume it's a spontaneous combustion but this is not true, it is a detonation hence the capacity to blow up a weapon. British cordite propellant had an abnormally high percentage of nitroglycerin which made it prone to cook-off, as well as burning hotter with more barrel erosion. This was the price paid for a more powerful propellant, on a volume basis. Cordite is a dibasic propellant, phlegmatised (what a lovely word..it means "calmed down") with petroleum jelly and treated with graphite as an anti-static agent. The stuff used by the Germans was also dibasic but with a much lower nitro content. US powder was mono basic so only nitrocellulose and much more heat-stable. The "nitrocellulose" referred to here is actually a highly selected product, the origins of the pulp are carefully controlled as well as the conditions for nitration and the post-nitration process. It's not just "nitrocellulose", and often the details are a carefully guarded secret. During WW2 there was no factory in the US producing cordite (which has a myriad of different specifications) so any ammunition produced would have to be nitrocellulose filled. Weapons like the British 6-pounder anti-tank gun that saw service also with the US army would have ammo with different propellants. Modern powders are often tri-basic, with agents like nitroguanidine included to optimise combustion rates and the like.

Modern ammo still cooks off pretty easily when the chamber and or barrel gets to hot and the most scary time for them to happen is when your clearing a stoppage and have the chamber/feed cover open and they explode back and up and all over!, had this happen with a SAW (MINIMI F89) in Australian service.

Ten years ago a Spitfire was dug out of a bog in the North West of Ireland and I believe six of its .303 Browning,s were recovered, these guns were turned over to the Irish Defence Forces who with minimal repairs were able to put them into working order. They had been in the bog for seventy years (1941-2011) see Dan Snows Documentary on the excavation and the firing of the Browning,s.

Some expansion on the why of open bolt and .303"- Unlike the nitrocellulose propellant used by the U.S., which when "cooked off" behaves fairly normally ( that is, causing the weapon to fire albeit unexpectedly) whereas Cordite actually explodes when cooked off. Violently. This is why the Brits had to go to rear searing on the Browning. The Goldmith series on the Browning is fascinating reading, if one can beg/borrow/buy them. Mr Goldsmith himself often attends the Big Sandy MG shoot in Arizona., and is a fun individual to chat with.

Makes one appreciate the importance of actually paying attention to what ammunition one is using. It matters more than we tend to think when we are kids and see people throwing what looks like any old bullet into a gun and it works. Had a friend with an old Imperial German Luger, 1916 manufacture, and he threw modern 9mm into it because it was all "9mm Luger." Didn't work very well, but he then got some 9mm actually made to Imperial German Military Specification and the gun ran flawlessly. Being young men mostly learning guns on our own back in the day, we had no idea that cartridges were more than just their dimensions, that the grains and powder mattered too.

@@jballew2239 Yeah, and damned if no one mentioned that back in the day. I can get why a cartridge, like 30-30, used mainly by civilians at first would vary a lot over time and place, but how cartridges that were used almost exclusively by a handful of military firearms ends up being so diverse is a bit harder to get. Before the 1960s, only a few specific military guns were really using 9mm, and arguably most 9mm in civilian hands were ex-military weapons. One would think any company making new ammunition would want to match the mil-spec so they could be sure it would work in the military guns that would be eating most of it. Somehow that is not the case. What a wacky world we live in.

The Gloster Gladiator, one of the first aircraft fitted with these, had a Browning in either (lower) wing and two Vickers guns (not Vickers K) synchronised to fire through the propeller. The Westland Lysander (it was armed for the Army cooperation role) had one of these in either wheel-spat, to put them outside the propeller arc and perhaps to make them easier to reload. The Lysander had high-mounted wings so putting guns in the wings would have made for a slow turnaround by ground crews. (There was also a Lewis or a K gun for the observer.) Sounds pathetic? the first He111 shot down by British forces in France was shot down by a Lysander! No guns were mounted on special operations Lysanders. In 1998, my colleague found that Westlands still had the metal-bending machine used to make the Lysander wheel spats and they were using it to make spare wheel-spats for the Westland Commando helicopter used by the Egyptians.

​@@BallisticCoefficient Answering the second part of your question. I think .50 BMG would have resulted in more German aircraft being destroyed rather than only damaged, with more Luftwaffe pilots killed or captured as a result. But not many more. Consider the fact that the RAF fought the Battle of Britain with simple reflector gunsights that didn't compensate for deflection shooting (pulling lead on a target). Now consider that by the end of the BoB, the RAF had lost many trained pilots, and didn't have time to fully train replacements. A more powerful gun doesn't do any good if the inexperienced replacement pilot (with only ~10 hours of training in Spitfires or Hurricanes) can't hit anything with it, especially when you consider that larger rounds mean the plane can carry less ammunition, making accuracy even more important.

@@BallisticCoefficient They did tests in the mid thirties to determine what was best, including testing the .50" BMG against the .5" Vickers. Although the .5" Vickers only had 2/3 the power of the .50" BMG, the damage done to actual aircraft structures was about the same and the .5" Vickers was lighter, used lighter, cheaper ammunition and had a higher rate of fire (less bolt travel.) They decided the Vickers might be better (the Italians and Japanese did indeed use the export version of the cartridge) but neither was as good as a 20mm! Some of this would apply to the .30-06" and the .303" MK VII. By the time they started to mass produce the .303" Browning in this video, they already knew that they would need 20mm cannons for fighters at least. (These took longer to develop and get into mass production, because the ammunition was new, used explosive shells and the guns were bigger and also more completely new than the Browning.) 4x 20mm became the standard for fighters from the Whirlwind onwards. With turret-mounted guns for bombers, the .303" remained the standard until after the war, although some .50" BMGs were installed on British-made bombers and American-made aircraft generally came with them as standard. There were difficulties fitting 4x 20mm into a Spitfire wing, so the standard there became 2x20mm and 4x.303, with some having 2x20mm and 2x.50" BMG. The RAF only used .30-06" when it was already fitted to aircraft they had purchased, but the calibre was in use in the army (as was 7.92x57) and this didn't cause any huge problem, but it wasn't seen as having any advantage, either. The attraction of the .50 BMG was that American factories were tooled up for it, but the .5" Vickers did see a lot of use on MTBs and MGBs with coastal forces. British factories made ammunition for all three of .303", 30-06 and 7.92x57mm; the latter until the 1960s as it was the standard for tank co-axial guns. The .30-06 Browning _did_ become a post-war standard for British armoured cars, some lasting into the era of the 7.62mm NATO. Some Shackleton maritime patrol aircraft, postwar, had turreted 20mm guns. The wartime British bomber with the lowest casualty rate was the Mosquito with no guns at all, but the ability to outfly German nightfighters.

The switch to open bolt makes sense. The reason that Spitfires and Hurricanes had the red squares where the guns were mounted was because they would freeze up. Water vapour in the air within the wings would condensate and then freeze as they climbed to altitude. Being open bolt explains why the ice would interfere with the operation of the gun, which is where the red squares come into it. They were canvas patches that would be glued over the gun port to stop the cold air from getting into the wings freezing up the guns, at least until the first trigger pull.

The very first Gladiator rolled out had two modified Vickers Maxim guns low down in the fuselage. Modded like the later Browning by lightening some parts and beefing up others, air cooling not water etc. However, under each wing was a tray holding a Lewis gun. The idea was to swap the Lewis for Vickers K/GO in due course. In trials the Vickers K/GO, with its Berthier ancestry, proved more reliable than either the Lewis or Browning as well as offering a higher RoF. However, belt feed (if reliable) wins out over pans and drums for very practical reasons (see the early history of the Beaufighter NF for a related tale of woe).

Open-bolt does have the advantage you mentioned of not keeping rounds sitting in the chamber when not firing, so they don't take as much heating. However, there's another advantage: cooling. In an open bolt system, when not firing, air can flow down the barrel, through the chamber, and across the bolt. Especially on a moving aircraft, this gives quite effective cooling of all the parts that are most exposed to the heat of firing, even during short pauses between bursts. A closed-bolt system will leave that whole section sealed up tight at the back, only cooled by airflow along the outside of the barrel.

Nice expo on the Aircraft Brownings, but a few omissions. The original Rear Sear ( Bolt rear release) was a plate which locked onto the slotted base of the rear underneath plate. The original rear sear wash pushed upwards to release the cocked open bolt to chamber a round. Once the bolt closed, an locked, a second firing sear solenoid on one or other side of the gun ( rectangular windows, depressed the firing pin sear sideways, releasing the firing pin. Bolt handle was a small, short round bar the locked into bolt by frame, and was retracted by Armourer with a lever type tool ( like cocking a .50 BMG) Some of the guns later had a hydraulic or pneumatic cocking system, for clearing jams in mid air ( as in Japanese Ho1 12,7 Br.Cannon). The reversibility of the gun included all the parts of the feed system...the feed block/shuttle, all the pawls, the bolt track, and even the downwards feed lever, the cartridge keeper was reversible. The RAF did supply flexible guns with spade grips, mostly for Waist or Scarf mounts ( observers) on flying boats (the Brownings replaced the Vickers GO ("K") In binary mounts). These spade grip guns replaced the solenoid ( rear bolt sear) with a simple lever arrangement in a covering channel. The Rhodesians did something similar in the 60s with Br.MkIII Guns for vehicle mounts. Another Omission, besides BSA and Vickers, J.Inglis of Toronto made very large numbers of .303 Brownings, for Commonwealth countries ( I have one BSA, and one J.I.T.: both wing guns, RAAF.). Lastly, the steel link is Almost identical to US .30 link, but the circular rings have smaller/larger diameters to allow for the different body, shoulder and neck diameters of the .303 MkVII cartridge. As original Browning 303 links are very rare, ( I got some in surplus RNZAF ammo back in the 60s), one can make do with .30 cal link, crimping the rear and centre ring, and opening outer front ring slightly....smaller body and shoulder, larger neck.

The Darne was in 7.5 mm French and I believe it had a push-through feed (someone please confirm this) which would not adapt itself easily to .303. The Colt gun was from the days of all-cloth belts and had the same sort of feed as the Vickers gun, the round was pulled out of the belt and lowered into the bore axis, therefore it worked fine with rimmed ammo. German guns used cloth belts with steel clips holding the round so they were push-through also.

A number of years ago, I had the opportunity to talk to a RCAF WW2 rear tail gunner in a (I'm pretty sure) iHalifax (not a Lancaster) with a dummy turret next to us. It was crazy how small the plexi turret was (you'd have to be like 5’3” to comfortably fit in it). He told me a few memorable stories. One being that in combat, the twin 303s felt like pea shooters when going up against the more heavily armed German fighters.

The claimed cyclic rate of fire was 1100 rounds per minute according to the tag on the gun. Should have bought it, but I got a 1919A4 ground gun a bit later which is probably better for shooting dirt.

As an aside, at a WWII re-enactment near St. Louis, I had my Humber MKIV armored car with my Browning MKII in my BESA adaptor (still for sale). Two of us drove the car there, one man short, the gunner. A friend said that his son would be glad to be the gunner and was quite familiar with a Browning. I told him to hop in. I was driving. He had nothing but problems that I could not understand as the gun worked flawlessly prior when I was the gunner. Next re-enactment my Browning malfunctioned. Later discovered a feed part broke. Only later did I deduce what was the cause of the problem. The man's son knew all about US Brownings, I knew nothing. He was trying to fire the gun with the bolt closed.

The .303 Mk 7 was loaded with cordite; the Mk 7* was loaded with nitrocellulose, making it a single base powder.

Just another point, the predecessor to the Browning was the Vickers type E machine gun (Vickers Mk. V) which was a closed bolt design. It was not troublesome regarding cook-offs mainly because it was much slower, in the 700 - 800 rpm range, and because it was used in synchronised mounts in the fuselage which slowed it down even more. Pilots were probably not allowed to fire long bursts in order to conserve ammunition, in the years of great parsimony.
@discerningscoundrel3055
@discerningscoundrel3055 2 жыл бұрын
Parsimony wasn't the issue. By the time they've paid for an aircraft and fuel, the price of the ammunition is basically irrelevant. The weight and bulk of it, on the other hand, was an issue; aircraft could only carry so much, and the more weight and bulk they carried, the more it hurt their performance.

Another great video. I believe the cyclic rate of the RAF Brownings was 1,200 rpm. In other words, Battle of Britain fighters fired 480 rounds in a 3 second burst. The Polish pilots were remarkably successful in the B of B partly because they opened fire at point blank range. That weight of fire would almost inevitably fatally hit crew and cooling or oil systems. There are many photos of Me 109s that belly landed intact after picking up a couple of bullets in the wrong place. The contemporary German 20mm gun was certainly more powerful but was restricted to only 6 seconds firing time rather than 15 seconds for the British fighters. The Browning also had another crucial attribute- it was utterly reliable.

I found a crashed Hurricane. There were plenty of rotten rounds but the guns were recovered during the war. Standard practice when recovering a badly smash plane- apparently this one dove straight into ground with only thin top soil (pilot had vacated the plane, wounded)- was to recover stuff like guns and instruments, bury or burn then bury on sight. The ammo had rotted up to the mean water level of the burial hole. So you would find a round with the bottom section missing- on carefully lifting the case, flake powder would fall out. I was know for setting off Cordite rounds (minus head) at school but I decided this time to not scavenge pounds of wartime explosives. It’s also known I know where the wreck is but have not been contacted. For years our garden had dozens of chunks of burnt out RR Merlin laying around eventually being thrown in the garbage.

As I mentioned in my comment on the Vickers K gun video, my father was an RAF air gunner in a couple of Bristol Beaufort squadrons (86 and 39) during WW2. As the mid-upper turret gunner he operated twin Browning guns of the type featured in this video. One of the things he told me about his RAF 'experience' concerned the reliability of the Browning's as fitted to these aircraft. Apparently, when the guns were fully belted, the feed pall would often slip over a belted round during the loading/firing sequence and cause a stoppage. Squadron armourers managed to successfully resolve this issue via a simple modification to the feed pall mechanism, however, when this problem and solution were communicated up the chain of command, the RAF, being the RAF, prohibited the squadron CO from making the necessary changes. This being the case the crews were forced to fly with a reduced defensive armament; to ensure the reliability of the weapons. Given that ammo was always a scarce commodity in an operational aircraft anyway, this seemly mindless intransigence caused considerable ill-will and resentment, or to be more precise; even more ill-will and resentment.

A lot of it comes down to advances in airframe construction; the wings of a WW1 fighter were too lightly built and too flexible to mount MGs steadily enough for accurate fire, but the engine mountings already had to be strong, so mounting the MGs near the engine made a lot of sense but required synchroniser or interrupter gear to fire safely through the propeller arc. The stressed-skin cantilever wings of fighters introduced in the 30s were radically stronger, allowing for stable mounts for machine guns, and thicker, too, giving room to store the ammo. Once it was possible to mount the guns in the wings, there wasn't really any particular reason to use synchronisation gear, and it came with downsides - not just restrictions on the use of open bolt guns, but if the gear malfunctioned it could be rather bad for the propeller

A number of these were salvaged from downed Huricanes and mounted to jeeps by the LRDG. These lacked any sort of manual firing mechanism (I think they were hydraulic) so they bodged something together that had a hinged pipe that applied pressure to part of the mechanism to make it fire. There is actually a picture of one of the LRDG wikipedia page, it is the front gun on a Chevy truck that has a Lewis on the rear pintle. Later on they got official stocks of them, which they used in pairs with the spade grips that actuate through a slot in the bottom of the receiver.

Never understood why Britain stuck with cordite so long when almost everyone else moved away from it after WW1 or even before then in some cases due to the detonation danger. Spontaneous detonation often even occurred in older cordite in storage as it became less stable over time. Some more stable powders developed between the wars also equaled or exceeded its performance, and even Britain did make some changes that helped, but seems odd they continued its use into WW2. Hopefully they had a good reason to stay with it so long but I’ve never found any good info on why they did other than cost.

The later model Spitfires had two Hispanos and two .50 Brownings. Ammunition load was 240 rounds of 20mm and 400 rounds of .50. To my knowledge the ammo boxes were about the same size in all four inner wing gun bays, so it seems that the .50 gives you a bit less than double the ammo in the same space. 20mm HEI is probably more than double the destruction of .50 API however. The P-47 is so enormous that it could carry a truckload of ammo of whatever kind you liked. IIRC consideration was given to fitting it with six 20mm, which is an utterly absurd level of firepower.

I wonder what the eight guns sounded like when firing together? 1150 cyclic rate. .153 rounds/explosions a sec. Also, the Gloucester Gladiator had the synchroniser mech. I know this reduced the rpm.

Guy Martin has a good video from earlier this year where he got the Paras to fire 8 GPMGs simultaneously at a Messerschmitt-sized target to try and simulate the effect. Much lower cyclic rate, but still sounded incredible!

@@slightlyagricultural Ah yes. See, that’s exactly what made me think as seeing that and knowing that the RoF was slower on a Gimpy compared to the Browning by a significant amount. I imagine it’s probably more of a tearing sound than the boom-boom-boom.

Blackpowder was known for being extremely dangerous. The old drawings of the duPont works show rows of three sided sheds on the river with the open side pointed toward the river. Later with the new smokeless propellants it was until recently a black art. You’d make up a batch and then test it to see what you had.

Nice to see the fangs of the Hurricane; would be great to see one day how they zeroed the .303, .30-06 and 20mm cannons on the aircraft sights and the whole patron of fire. The inside guns shoot 1st? they shoot all at once?, the different caliber guns all had the same zero? because they didn't had the same fire rate.. and all aircraft stuff, would be nice.

I think they just parket the aircraft in some pre-set area and zeroed it exactly once, and then you could adjust it. I know for sure it was customisable by ground crew to have different guns firing at different ranges of convergence.

I saw something years ago. The planes were parked in firing spot and each gun was adjusted to hit an target downrange. Not so much as zero but to hit an area.

IIRC, Military Aviation History has a video on this: Basically, the MGs and cannons were on different triggers, the guns were not all zeroed to the same point, although they were zeroed several hundred yards away. The guns were set up such that they created a pattern instead of all firing straight ahead; this made it easier to hit more parts of an aircraft.

Very cool, thanks. Ian; probably not a forgotten weapon, but going with aircraft weapons; any chance you could do a piece on the Hispano 20mm cannon? Especially on the de Havilland Mosquito's pneumatic firing mechanism delay! Top drawer, Sir, as always.
