  2. The Finns actually worsened the sights, asking for them to be zeroed at 100m instead of 200m before the rifles being delivered. That way they were practicaly useless past 150m, well into combat distance.

  3. "because we wanted to make an high quality firearm with a reliable and clean action". "but why I'm not an AR15?" "because we wanted to make an high quality firearm with a reliable and clean action".

  4.  @alessandrorona6205  BTW, in that competition, despite the problem with the safety, Ian won a stage and Karl won two, so there had not been any floor mopping, sorry.

  5. Many pistols designed to work with 9mm handle the .40 S&W pretty well.

  7.  @angry_ike7628  7.65mm Parabellum produces 412 Joule of energy, not ft-lbs. Those are 304 ft-lbs. Not really different than the 8mm Roth-Steyr (that would easily surpass it with a bullet of comparable weight). Overall lenght: .30 Super Carry, 29.7mm, 8mm Roth-Steyr, 29,0mm 7.65X20 Longue, 30.24mm Bullet diameter: .30 Super Carry, 8mm, 8mm Roth-Steyr, 8.16mm 7.65X20 Longue, 7.85mm Base diameter: .30 Super Carry, 8.8mm, 8mm Roth-Steyr, 8.85mm 7.65X20 Longue, 8.53mm Bullet mass: .30 Super Carry, 100gr, 8mm Roth-Steyr, 113-116gr 7.65X20 Longue, 77gr Energy: .30 Super Carry, 470J 8mm Roth-Steyr, 390-410J 7.65X20 Longue, 297J. So I confirm, the .30 Super Carry is more similar to the 8mm Roth-Steyr, both for dimensions and energy than to the 7.65X20 Longue, that shoots a much lighter bullet with much less energy. The 7.65 Parabellum has very similar performances to that of the 8mm Roth-Steyr, especially considered that the 8mm Roth Steyr would develop more energy with a 100gr ball (a la .30 Super Carry) and even more with a 93gr ball (a la 7.65mm Parabellum).

  8. It's more "being big enough to persuade three ammo manufacturers to produce your wildcat cartridge". The rule was introduced specifically to stop handloaders of super-hot 9X21 ammos (and so make the 1911 stay relevant). S&W answer had been "OK, Now that the board has stopped all this 9X21 guns, I make it 9X21.5 and persuade three manufacturers to produce them while I build 10.000 guns".

  10. That's what happens when an inventor gets enamored of an idea. At a certain point, he realizes it's impractical in respect to other, established, solutions, but he wants to make it work. However, let's not exagerate. The functioning is complex, but the individual pieces are rather simple to make. For a comparison, the Zb. vz 26 / BREN was simple in its functioning, and had less moving pieces, but the bolt and carrier are the nightmare of a machinist. Fact is that too many moving pieces are a problem by itself, since it multiplies the things that can go wrong.

  11. Overlooked part. The infantry MG only weights 8.4 kg (7.4 kg the aerial one, with lighter barrel and without stock) that's VERY light. However the lack of a quick exchange barrel limits its effectiveness.

  12. It's for strip field. Statistically, the recoil spring and the firing pin are the parts that have to be be replaced more often, and the bolt assembly and the gas ports are those that need cleaning. This design grants access to all of them in seconds.

  14.  @doublepiedavid8908  Despite having been made specifically for a carbine, and descending from a class of rifle ammo (those for the Winchester Model 1907) it's normally considered more akin to a pistol round. 7.5 FK, that's specifically a semiauto pistol cartridge, is more powerful than .30 Carbine for the same barrel length. It's not an unicum. Much of the classic cartridges of lever action rifles are less powerful than a modern .357 Mag.

  15.  @markcoffman9522  Oh, please... That story again... The Beretta was simply the best gun in those trials. Like it or not.

  16.  @randymagnum143  Please... The M9 is one of the most famous handguns in history,. the P7 is just a curiosity.

  17. King Leonidas 5.56 NATO bullet diameter is 5.70mm. .22LR bullet diameter is 5.72mm. The difference obviously is in how much pressure there is behind the projectiles.

  18. I'd really like if Ian manages to put his hands over a Variara SMG (there are at least 12 surviving samples, at least one of them in a private collection). It's an insurgent weapon (it was manufactured by Italian partisans during WWII), but it's really the king of insurgent SMGs. Sten-style bolt and charging handle slot, TZ45 style barrel assembly / receiver, FNAB 43 style folding magazine holder (for MAB 38 magazines) MAB38 style double trigger for full auto-semiauto, MP40 style folding stock and pistol grip, original grip safety. Its' like someone decided to put the best features of all those SMGs in one design, that was still easy and cheap to produce and field strip.

  19. An MMG is a crew served weapon. if one of the crew is wounded, one of the infantrymen takes his place, because the MMG is more important than a rifle.

  20. Because this is metal and blowback (so is the mass of the slide that dealys the opening of the breech) and the Glock 19 Gen 19 is polymer and breechlock. Fairer comparisons are the the CZ83 and the Walther PPK. the Beretta is lighter than both.

  21. The only thing the Italians got wrong in 1891 was the adoption of a too long and heavy bullet. As many others at the time they were too concerned with the performances of the bollet at very long distances, that proved to be impractical in reality. Had they adopted a lighter bullet, they would have had a 6.5 Grendel 100 years in advance.

  22.  @Jay22222  The M16 had a dual aperture sight, the battle sight was zeroed at 250m and used between 0 and 300m. The long range sight (300m to 400m) was never used, since the US Army didn't (and doesn't) train for distances longer than 300m.

  23. Mind that this is a disassembly, not a field strip. A normal field strip (to clean the gas chamber, inspect and maybe replace the recoil spring, clean the bolt and maybe replace the firing pin) can be made in seconds without tools, that was not a given at that time.

  24. The Italian Navy adopted it, but they didn't need many of them. The Army bought it in some thousands of samples as "mobilitation weapons" (to be stored and used if needed). They had been lastly seen in Afghanistan, abroad the Mangusta helicopters.

  25. The Marine Corp adopted the Beretta M9A1. Some special unit was given that Colt, without any competition, mostly due to Gen. William M. Keys connections, and had little else than just problems with those.

  26. Fact is that you can manufacture far better shotguns in a third-world country for the same price.This one is just a collection of bad ideas.

  27.  @goobcity  "There are reasons why belt fed LMG weren't a thing still in WWII (and the GPMG concept took decades to impose itself after the war). A belt-fed LMG has MANY problems." The MG42 was a GPMG. Used as a LMG, it used a 50 rounds belt in a can (the Guttromel). It took way less to change 3-4 magazines tha a single Guttromel. The Browning 1919 was not a LMG either. It was a MMG pretending to be one. It had even more problems with weight and fixed barrel.

  28.  @davidvarnes7708  For 1934 It was simple to make too. The BAR, BREN, MG34 and Type99 (and both the BREN and MG1934 had been selected in 1938, the Type99 in 1939) had more complex machining. Among the most used LMGs of the time, Only the DP28 could be considered simpler to manufacture. But generally, though I like it, it seems like a promising prototype put in production before all the elements had been figured out throughly. Very good and simple operating mechanism, barrel change mechanism, general ergonomy, controls, gas settings… But three sets of lugs? That bipod (I’ve seen better in WWI)… no handle to grab a scorching hot barrel… And that magazine… It could have easily been so MUCH better.

  29. There's infact a clip about a Ukrainian anti-drone unit that used a Beretta MG42/59 mounted on a pick-up.

  30. I'd prefer to be the one wielding "this shit" and filling with holes that strange guy I saw advancing in a WWI battlefield with a sword in his hand.

  31.  @Pwnulolumad  The operation is carried on by active duty military personnel, with the standard equipment.

  32. Both Colt and Beretta, when they experimented their 9mm blowbacks, noticed that the hammer was a weak point of the system. The very fast recoil of the slide tended to break it. Maybe Bernardelli had the same experience and decided to go for the striker.

  33. The rubber sealing on the Chassepot used more material than the thin disk on the Carcano, and required to be changed every few shots anyway (that costed time in action).

  34.  @hannibalkills1214  if... if... If the enemy was not armed with firearms, an MG wouldn't have been needed at all. "Reality doesn't work like that". The German army's reality was that they had to adapt to the situation like everyone else, and a tool that limits your ability to adapt is a liability. The BAR was suboptimal because it's firepower was very limited in respect to it's weight (among some other problem) due to the fact of not having a quick exchange barrel. All in all, with all it's limitations, the Breda 30 was a better LMG. Simply the US had the industrial capability to "throw more BAR to the problem". Also the ability to "call for Arty" made so that MG tactics had always been neglected by the US Army (still today). IE, in a British squad, every grunt was instructed in how to use the BREN and, had only one remained alive, he was supposed to use the BREN. In a US Army squad, only the BAR gunner and his assistant were trained in using it. The GPMG concept (and the centrality given to the MG tactics by the Germans in WWII), did born because the WWI peace conditions limited the number of both LMGs and HMGs for Germany (and practically banned mortars and artillery). To have an MG that could cover (even with some limitations) both roles, in a certain sense, doubled the allowed nuber.

  35. The 91/24 mantained the old rifling, infact they are known to keyhole. However those were intended to be stopgap weapons for rear echelon troops, the ones that in WWI had been armed with the converted Vetterli.

  36.  Zach cash  The Marine Corp adopted the Beretta M9A1 in 9mm. Some special unit was given that Colt, without any competition, mostly due to Gen. William M. Keys connections, and had little else than just problems with those. That's why it had been replaced after only four years of service, to adopt a 9mm.

  37. Actually the price point didn't matter at all in the P7 not having been selected in the XM9 program. The P7A13 didn't even reach the cost comparison phase of the trial. It was eliminated because it fared atrociously in the reliability tests. The 92F was the only handgun that passed those tests. The minimum threshold had to be lowered for the SIG P226 top pass them, since the Army wanted to have at least two handguns to compete on price point.

  38. There had been several 9mm double feed pistols that weren't particularly wide. The Type-92 is probably the most "normal looking" example.

  39. You mean a simple blowback system? Practically every round can be fired using a blowback system, but, in a simple blowback, what prevent the action to open too early (when the pressure in the chamber is too high, so the walls of the case are stuck to those of the chamber, and pulling back the case can cause a case rupture) is simply the weight of the bolt. The more powerful is the cartridge, the more heavy the bolt has to be. A MAB38 (wooden stock 9mm SMG)already weighted around 4 kg. A full power rifle round would require a bolt so heavy to make the rifle unmanageable. So delayed blowback systems are used instead. Lever delayed like in the Famas, roller delayed like the HK G3... but delayed blowback system are really not more simple to produce than gas actuated ones.

  40. For strange that it may seem, it had been higly effective. The number of Villar perosa MGs in the Italian infantry battallions increased throughout the war, and the weapon had been copied by it's enemies ( "Frommer-Stop M1917" and "Sturmpistole M-18"), that probably had the occasion to appreciate it so much that they wanted it themself.

  41. Now imagine to be on Omaha beach. Germans are shooting at you from small openings in concrete bunkers. You could have: 1) a MKII hand grenade. You have to get close enough to throw it into the bunker. 2) a knee mortar. You have to shoot and hope the bomb hit the right spot 3) a M91/28 grenade launcher, or a Brixia mortar. You can aim at the bunker openings from over 100 distance. What would you choose?

  42. The heavier the firing pin, the easier for it to activate the primer. The long travel and the fact that it can't sart moving until the bolt is in battery is meant to slow the ROF too.

  43. The complain about the dispersion at Gaudo had been made by Adm. Iachino, but he had to justify his fiasco of the subsequent night someway. We have the direct witness of the Fire Director of the Vittorio Veneto, that didn't considered the dispersion of the salvos to be anything out of the ordinary. Simply the Vittorio Veneto fired from very long distance, in two different actions of 10 and 19 salvos each (between the two, the British ships were completely covered in smokescreens, so the Vittorio Veneto had to re-adjust the aim when it spotted them again) vs. two ships that, with a time of flight of the shells of over 40" could manuver to avoid the shots when they spotted the blasts. The Battle of the Espero Convoy already demonstrated that, even at half that distance, it was nearly impossible to hit a ship that was performing evasive manuvers (or in the battle of Denmark Strait, when POW decided to break the contact, the Bismark wasn't able to land a hit any more).

  44. More than the metallurgy, I think the problem was the hurry to press it into service. The M1 Garand was developed for more than ten years. This, for maybe one year. Having a little more time they could have ironed out the problems. IE, to put a dust cover on that opening in the receiver was not really complicate. But, in 1917, the priority was to manufacture a lot of rifles in the shortest time possible.

  45. It's two metal surfaces (in this case slide and frame) wearing rapidly when sliding against each-other, because the crystal structure of one captures and "tear away" the surface crystals of the other. Stainless-on-stainless friction is particular subject to galling. It's the reason all-stainless-steel semiauto appeared so late on the market (the 1983 Randall 1911 had been marketed as the first really reliable all-stainless-steel semiauto pistol). In 1976, when the Mamba had been marketed, the problem had yet to be solved.

  46. Had it been an Inertia failure, he would have had a failure to eject, but the ejection was very strong and consistent. Probably, due to the right-handed grips, he inadvertently hit the slide-stop lever during the recoil, infact the gun didn't fail to feed (like in the round hitting the ramp and being stuck there), but simply held open.

  47. Had the SA80 been designed by actual gunsmiths, it could have ended up to be something similar.

  48. The problem with toggle delayed actions, like that of the Pedersen, in sporting firearms is that there is a VERY slight difference between too little angle (the action is too locked, and doesn't cycle) and too much angle (the lock doesn't delay the opening enough). In military firearms that's less important because there's ONE service cartridge, not many different for case material, bullet weight, propellant...

  49. It rested on the base of the barrel when the bolt was opened, so directly ahead of the new bullet, and was expelled with the next shot.

  50. Crew served weapon. it feed from one side, where there are the full box of ammos, and eject from the other side, where there are the boxes of spent strips.
