  1.  @kevintang5473  You are welcome. There's a great animation of the working of this gun. https://www.youtube.com/watch?v=2SwNqvUZSW8

  2.  @bryangrote8781  Ian forgot one issue with shotgun shells. Due to the rapid decrease in pressure in the barrel, and so decrease in temperature, shotgun shells are ineherently dirtier than smallbore bottleneck ammo. That’s why recoil actions had remained relevant for so long in shotguns (and still are) while they had become little more than a curiosity in rifles, and that’s why gas action shotguns have complex self-cleaning pistons, often with multiple ribs, while rifles have much simpler ones. The disassembly of the Auto-5 is really not the simplest, but other long recoil action shotguns simplified it a lot.

  3.  @pdalia  ​ The Gewehr 41 was an abomination made in 1941 (so not near the end of the war) that was later corrected by copying the Soviet SVT40 (Gewehr 43). The fact that the Germans (like the Italians, Belgians, Czech and so on) made some good design doesn't mean that they make only good designs. A lot of manufacturers make good barrels.

  4. +Luuuukich The 9mm parabellum is not a "far superior caliber". Ballistically a 9mm Glisenti projectile at the muzzle has the same speed of a 9mm Para projectile fired from 30 meters away. Since 9mm Para projectiles are lethal well over 100 m distance, the difference at tipical pistol distance engagement is negligible.

  5. It doesn't seem there is some mechanism that unlocks the lever from the slide when the shooter is pulling the slide, so it seems that the breech is not locked and can be open by recoil alone. All the lever does is to add some mechanical disadvantage to the linear recoil, so this is a delayed blowback action.

  6. Unfortunately in Europe there was only a limited market for 9mm Para pistols at the time. Or you managed to get a public contract (army, police forces...) or the model was doomed, regardless of the quality.

  7.  @Matt_The_Hugenot  Unfortunately the Italian competitor in the market was the Beretta M1951, a really good pistol. But in a small semi-artigianal company like Bernardelli at the time, there was simply A LOT of people that knew how to assemble an handgun, starting out of nothing but using existing solutions (nothing in that pistols is really new, they are assemblies of well estabilished ideas) without a blueprint. Probably someone simply said "why don't we try to produce a 9mm para pistol?" and the answer was "why not? Maybe something good can came out of it".

  8. Scotti used the same design scaled up in several calibers, up to 37mm automatic guns. Chinn, in "the machine gun" higly appreciated it. It was economical and practical.

  9. No, it's called an "expander lock" patent US461968A. Due to the position of the pivots, the recoil tend to push the intermediate lever against the frame and not to make it rotate. There's no limit to the power of the cartridge that breech can control, as long as the frame is strong enough.

  10. The PA-15 uses the same system of the Savage 1907.

  11. No, it's a piston. It's not an open tube. Elklund's patent describes it as a piston, and it has the same external diameter than a standard gas piston (IE that of the M1 rifle) because it's a gas piston, while what's in the carrier is a cylinder. "Direct impingment" doesn't exist. What pushes the bolt carrier back is pressure (of the gasses) for surface (of the piston), like in any gas action. That means that, had that piston had a smaller diameter (mantaining the same internal gas tube) the action wouldn't have worked. Because the pressure would have been the same, but the surface wouldn't have been enough. Most rifle pistons (IE, again, that of the M1 rifle) have "no gas sealing mechanisms" or "rings". The machining is accurate enough to retain enough pressure for the action to work. In this case, also, there is the protruding cylinder of the carrier going into the receiver, and making very difficult for the gasses to escape.

  12. It compensated for worn-out barrels and ring-locks. One position was used when those elements were new, and the other when they were mid-life and would have opened the action too early.

  13.  @ramdom_assortment  That style of decocker (that Beretta introduced in the Cheetah) doesn't decock the hammer completely, but put it in half cock position. That means that debris can enter between the hammer and the firing pin when the gun is "decocked", or that they can do it before, so acting as a medium between the hammer and the firing pin when the gun should be safely decocked. Beretta/style decocker have a further level of safety. the hammer is completely decocked, so it seals the space behind the firing pin, AND the firing pin is out of the way when the gun is decocked, so nothing moved by the hammer can hit it. As said, that is the safest place to put a decocker. One can like other ways to make it, but there is a reason if Beretta puts it there.

  14.  @Kuschel_K  The Brits used the Bren.
    2
  15.  @Kuschel_K  They used the Bren for their tanks, both as AA machinegun than as alternative to the BESA in coaxial mounting.

  16. Belts are closed?

  17.  @loquat4440  the Villar Perosa fired M915 Glisenti load, that are more powerful than the standard M910 Glisenti pistol loads and are like very mild 9mm para rounds (125 grains slightly subsonic).

  18. Probably the magazine spring weakened. You need spring tension to retain ammos in a downward magazine.

  19. Rotating barrel, tilting barrel and tilting locking block are different ways to obtain the same thing, a short-recoil breechlock handgun. Every system has its pros and cons.

  20. the Revelli 1914 was, all in all, a good HMG. The 1935 conversion not so much (it fired from a closed bolt, that's indifferent for a water-cooled MG, but not so good on a air-cooled one) despite having at least a good feature, an ultra-modern disgregating metallic belt, but it was intended as a cheap stopgap. The ones that had been converted, had not been in exchange to other models, but simply to have more MGs on the field. The 7.35 carcano cartridge was developed to completely replace the 6.5 one but, as the war broke out when the conversion just started, the plans were cancelled and the 7.35 cartridge simply had not been used on the field. Austrian captured weapons had been used almost exclusively in AOI (Africa Orientale Italiana, Italian Eastern Africa, that means Ethiopia, Eritrea and Italian Somaliland). Due to the geography, those lands would have been completely cut off from the mainland in case of war with the British Empire (like they infact did), and the local troops would have had to use only what they already had there up to exhaustion, so logistic was less of a issue. The easiness of servicing was among the things Allied reports of the time praised about the Breda 30.

  21. The Beretta MG42/59 reduces the fire-rate by reducing the pressure in the muzzle booster (infact its muzzle booster has small holes perforating its "dome"), however is a delicate balance since, by reducing the speed of the bolt without enhancing its weight, you reduce it's energy, that's required to pull the belt also.

  22. The Italians 129 Years ago, 6.5X52.

  23. In theory you can made a Tribuzio in .45 ACP capable to accept 1911 magazines. And it will still be quite compact (the bore axis is so low that the recoil will be even pleasant).

  24.  @doraran5158  It's not splitting hairs, it's an information. Mussolini was not "the former head of the Italian Socialist Party" (you didn't write "that segment", you wrote "the Italian socialist party", that has a precise meaning) but the director of a Socialist journal that was kicked out of the Socialist party as soon as he adopted an interventionist position for Italy in WWI. The study of history is based on correct informations. One can accept the information and thank for it, or whine because he preferred the wrong one he believed before. The rest, as said, is a political rant I'm not interested in.

  25. And it was not really needed. The BM59 saves the M1 Garand trigger group by adapting to it the M2 Carbine selector.

  26. They should have used Hollywood engineering.

  27. The second. In theory, with the legs closed, the gunner, or servent, was supposed to be able to grab the scorching hot barrel to swap it (already the fact that, in the middle of the action, he was supposed to close the bipod and extract the barrel, while the open receiver had to be laid down, on sandy or muddy terrain, because there was no more a bipod to hold it, demonstrates how retarded the design was. Any other LMG design sorted that out since the late '20s) In practice, asbestos gloves.

  28. There were blanks, and firing ones, the laters in 6mm Flobert or in .22 Short.
    2
  29. Both the Fiat Revelli 1914 and the Breda 37 were simple and effective.
    2
  30. Single locking lug at the top. All the Breda gas actions, up to 37mm automatic guns, used that lock.

  31. I'm starting to reevaluate the Brixia mortar.
    2
  32. That one was in 6.5. For the rest it was the same rifle.

  33. To think that nowadays 10mm Auto is fired by compact polymer-framed guns (IE Tanfoglio Force/Witness Polymer).

  34.  @mistakenotou7681  a team of three for a LMG in WWII is actually a reduced team. A US Army B-team (the one with the BAR) was composed of four men, gunner, assitant gunner, and two ammo bearers. A US infantryman in WWII carried 88 rounds in combat, so 3 guys with M1 Garand would have had only 264 rounds to fire. The Breda would have just changed the first barrel.

  35. Also the sight is zeroed a 200m, that's convenient to hit a human-sized target from 0 to 300m by just aiming at the center of the torso, so 100 yards is close to the point of maximum elevation over the line of sight.
    2
  36. "people not obsessed by AR-15s like Americans are" is more accurate.
    2
  37. The live round simply fell off in between of the normal cycle due to a worn out (100 years old) magazine spring and gravity. You need spring tension to keep rounds in place in a downward looking double-feed magazine.

  38. M14. "A rifle that can't even stand up on a wooden block."
    2
  39. Any long firearm can hit a human-sized target at 80m max. Even a pistol can do it. Oswald's Carcano was as accurate as a brand new M14. That's nothing to write home about for a bolt action rifle, but more than enough for the job. There had not been any magic bullet. Oswald's second shot flew almost straight from the barrel to Connally's wrist. Only then, being very slow at that point, deviated to hit the leg.

  40.  @grc70  there were plenty of MAB38 magazines around, and they were pretty well made too (double stack, bouble feed).
    2
  41. 910mm, with a 18" barrel.
    2
  42.  @jeromevuarand3768  All the pins holting the trigger group parts are simple rivets.

  43. Breda was a steelwork, locomotives and other railway machinery manufacturer, first than starting to build weapons, and still is. BTW it still makes shotguns too.
    2
  44. They got carried by their own dreams. For one and half million rifles, ammo availability would have been a problem. For 15.000, 50.000 or even 200.000 rifles, there were plenty of ammos already available. Better issuing a repeater with 400 rounds and call it a day (hardly a Volkssturm militian would have survived enough to fire all of them anyway) than issuing a single shooter even with 10.000 rounds.

  45. The lands of 7.35 barrels had exactly the diameter of the grooves of 6.5 ones. 7.35 was the smaller caliber that allowed to obtain new barrels simply cuting and reboring millions of WWI long rifles' worn-out barrels the Italians had in the deposits, while switching to a lighter 6.5 meant to manufacture new ammos AND new barrels. To switch to 7.35 was a cost-saving measure.
    2
  46. The frame mounted safety is not an "improvement". It was there on the original Beretta 92, and it's placed there on any 92 model that has not a decocker.
    2
  47. All the Carcano episodes had already been filmed, so, even if he understood by now, they'll not be fixed.
    2
  48. Nine guys were needed to CARRY THE AMMOS. Do you think those grow spontaneously alongside the MG (in canvas belts)? A MMG (HMG then) could fire THOUSANDS of ammos in a single action. Were you planning to carry them with three guys?

  49.  @tatumergo3931  Not really. The concept of the automatic weapon as the centre of the infantry formation came form the observations on WWI, and is typically European. In WWII it was not only of the Germans, but also of the Brits and even of the Italians. The weapons were different, but the concept was the same. That's why, IE, all of them concentrated more on the development of the automatic firearm than on the infantry rifle. From this concept comes that the automatic weapon is a crew-served weapon. All the infantry squad is a squad of ammo and spare parts bearer for the automatic weapon. The American concept, that still persists, is that of the infantry squad as a squad of riflemen with the automatic weapon as support. That's why, IE, the US, in WWII, had an exceptional rifle, and a subpar LMG. That's why the XM250 had just been selected as SAW for the US Army. The ideal of the Ordnance Corp is to have the MG served by a single men. The XM250 doesn't even have an attachment point for the tripod, because none is going to carry a tripod, nor a quick exchange barrel, because none is going to carry a spare barrel. The MG gunner is going to carry all the belts for the gun, and the 400 rounds he can carry in total are not going to overheat the barrel.

  50. That the rifle is still working when any semiauto had already given up.
