6.5mm CBJ is *very* interesting...

I do want a 22tcm pistol.

Sweden started using the M39B for the SMG, a 9mm AP in 1955, after reviewing combat reports from the Korean War. Denmark a NATO member got some ammo from Sweden and repackaged it as M/41 Steel Jacket. The Danish M/41 9mm can be very different and from different sources. Using a magnet and weighing the OAW, can give and idea of what you got.

There is an experimental gun developed arround the 6,5x25 cbj, called the CBJ MS

XD ...I wish you were joking. :(

Fucking spilled my drink

Yeah, I totally agree. And I must contest 9-hole stating the 7.62x51 stanag as effective...

It would have penned the Russian armor at least.....

Doubtful. Speed is one of the most important parts about penetrating armor and .308/ 7.62MM NATO loses a lot of velocity out of a short barrel.

NATO had plenty of cartridges that could penetrate standard Russian armor, though armor piercing rounds were not the standard round. The exact same is true for the Russians as well though so kind of a moot point lol.

So this may be ignorant, but where does something like .357 sig place when compared to the BOZ? If you squint hard enough, it starts looking similar in profile to a halfway point between Tokarev and the BOZ round.

@@geekmansegraves VERY close, in fact I have toyed with a .357 SIG load using a caliber appropriate T6B projectile. Not enough time or resources have halted this. The powders that work best for the 5.7x28mm also work very well with the .357 SIG and I have a .357 SIG barrel for my Delta Elite.

Oh really? No wonder then. 10mm is often weaker in general since they are 9mm guns modified to fire 10mm. No wonder 224Boz guns don't last.

@@jamesbridges7750 would love to see that.... Though 9x25 is not a thing. 8mm at 123gr? Kurz? Even 8mm Mauser seems to be going away. I want to see 8mm return since I have a Mauser, but reality though?

Which is why other 5,7 x 28mm guns have stoppages etc when using non-FN ammo. I doubt they have figured out the FN lubricant formula accurately enough. Most FN owners seem to have very few problems when using FN ammo. Remember the PS90/Five seveN were ALWAYS going to be niche firearms/calibres anyway. Realistically, FN was never really going to replace the very well-entrenched 9mm parabellum anyway - the logistics implications clearly prevented that from the get go. "Rear echelon troops" is a limited "market" by definition! However, the P90 was quickly adopted by numerous Special Forces and Law Enforcement Agencies worldwide, contrary to all expectations. Some detractors seem to have missed this. Replacing an entrenched weapons system/calibre is extremely difficult and expensive, as demonstrated by the whole NGSW programme, which is still only partially adopted, with 5,56mm still firmly entrenched for the most part.

Another Indian furearm enthusiast? Sheesssh

Yup, I really like their logic: "we need small ak": AKS-74u, "We need long AK": SVD, "We need quiet AK": VSS ... And so on. They save so much money and time not trying to "reinvent" things they will likely barely use in the first place.

@@unarmored9973 And sometimes this logic has its disadvantages, for example rimmed 7.62x54 which doesn`t allow to construct high - capacity magasines for SVD, or lacking supersonic suppressors among the troops. BTW, SVD is not an upscaled AK, it is completely different inside, and VSS has some major differenses from AK either

Has it though? You’d think if “it works so well for them” Russia would be in a better state than it is……or ever has been

@@unarmored9973 PK is completely different, like m249 and m4. I can agree with ots-14, pp19 and saiga which are same aks with different calibers and designs. Maybe Val too. But if you say that svd is ak, than let's say m417 is a custom ar15, mk18 is a fancy ar15. Svd differs more from AK than g36 from m4. It just looks familiar because of same production methods used(large steel stamping, steel magazine, wooden parts), but all major internal parts are different

@@user-if4zv5nj5m I am NOT saying SVD is the same as AK. Nobody would say that! haha. I do not mean "Platform". Such as: AK74, AK100, AK101, AK102, AK103, AK104, AK105, AKM, AKMS, AKS74u, RPK74, RPK... And so on. Those share enough parts interchangeability, I would never say that the SVD is part of the same "Platform" as AK. Everyone classifies weapons different for "family" or even "series". There are many different books written about how every author thinks firearms should be categorized together into families and series. So many different reasons. - There is DEFINITELY no consensus, even by the manufacturers. Some people think caliber is enough to create a new family, others think operating system is more important, others think combat role is what determines it's family, others think simply by how it looks - There is absolutely no way to grade similar firearms into defined families that we all can agree upon.

@@9HoleReviews I sincerely hope that it has some effect. We've been stuck in this mentality of not thinking things through for far too long. When I got out of the Marines they had finished adopting the PMAGs, and it was apparent that nowhere in the testing did they consider how they fit in the current issue magazine pouches. According to my old boot who became the armory chief, the new magazines were apparently too thick to fit two of in the at-the-time currently issued double-mag pouches, so you ran into situations like SNCOs telling Marines to soak said pouches in hot water then stretch the hell out of them so they would fit.

That’s kind of what they’ve done. Look up 9x21 and the SR2 Veresk. 9x21 is an absolutely nasty little round, longer than x19, and loaded HOT. Out of the pistol it’s chambered in, it’s rated to do far better than a 5-7.

I disagree. I think concerns over bulletproof vests were at the forefront of people's minds, especially with the concerns over policing. Having a 20-round handgun that can penetrate IIIA is exactly what SWAT and CT personnel need when dealing with high-profile incidents. Works in Counter-Strike, lol. The generally improved performance is perhaps actually more important, though. I mean, having more power and capacity than 9 mil, with less recoil, seems like a great deal, and armour is not statistically all that relevant. But they seemed to have been more focused on the vest thing, and I can't blame them. I really don't like the idea of my rounds getting stopped by a few layers of fabric.

@@jonathandoe1367 NATO is strictly a military alliance with no consideration for law enforcement needs or wants. In the 90s/early 2000s, vests (IIIA or otherwise) weren't exactly at at the forefront of concerns. Iraqi, Somali, Serbian, and Taliban opponents almost never wore them. However, the future was very uncertain at the time and NATO seemed to want to err on the safe side, so some -vaguely-defined- *arbitrarily-defined armor-piercing capability was desired to anticipate future threats.

The objective, as 9-Hole alluded to, was primarily to replace the outdated 9mm NATO/Luger/Parabellum with pretty much *anything* better - hence, the arbitrary CRISAT requirement to specifically beat the 9mm. 9mm ball/FMJ's garbage performance record was known well before the trials (look up Mike Durant's horror story with his MP5K in Somalia in "In the Company of Heroes" - a great read by the way), so it was a very fair decision to want to phase it out.

@@eddietat95 You bring up very good points, and I don't disagree with any of them. However, as a counter-point, consider this: European countries typically rely on their military forces for policing and counter-terror work, whereas the US is Constitution-bound to leave its military out of law enforcement. In battlefield situations, handguns are almost never used, and pistol-calibre carbines have been mostly superseded by short-barreled intermediate-calibre rifles, like the M4 and such. In their actual usage, the P90 and MP7 are mostly used by police and counter-terror units, and few handgun-calibre weapons see much use on the battlefield at all. The countries that relied upon the military for policing were the same countries that pushed for a round that could defeat common civilian body armour, and that round is mostly serviced for police and CT use even today. Does that really sound like a coincidence? Don't get me wrong, the 5.7x28 would make a better service sidearm than 9mm, but sidearms are rarely used at all. As for PDWs for vehicle crews and such, typically intermediate-calibres are still used for that. Hilariously, the US issues its tank crews with shotguns and LMGs for its tanks, and an M4 for every tanker, so I don't think they're very interested in PCCs or SMGs for battlefield use, but maybe they have more traction in Europe. Sorry for not getting back to you earlier. My internet has been a mess recently. Look forward to hearing from you again. :)

@@jonathandoe1367 You're absolutely correct to point out that pistol/PDW-caliber rounds are rarely used in actual combat, however, they are still issued en masse - including in the US military. In the US Army alone, M9s are issued in the tens of thousands to NCOs, vehicle drivers/pilots, inside-the-wire types, and the standard rifle platoon issues 4 M9s for 2 M240 gunners and 2 officers. I also saw loads of folk with M9s while at the Pentagon. In the early years of GWOT, M9s were used extensively when the M16/M249/M500 was considered too unwieldy when clearing particularly tight rooms and tunnels. SMGs, however, have almost entirely been replaced by the short-barreled carbine, though they remain in stockpiles for SF use. Special forces/CT units aren't really relevant in this discussion since their choices are generally funded/sourced elsewhere, in smaller numbers, and with more freedom of selection. The reason why NATO committed to this push away from 9mm, performance aside (and as 9-Hole also mentioned), was that - at the time (the 90s/early 00s) - many countries were finding that their 9mm SMGs/pistols were reaching the end of their scheduled service life. These had largely been purchased in the early-Cold War era when NATO started standardization efforts (think Hi-Powers, Uzis, early MP5s, etc.) and it was nearing time to replace them. Out of convenience, it was agreed to maintain NATO standardization, but to switch en masse to a new caliber entirely that would at least have *some* general improvement over the almost century-old 9mm FMJ without breaking Geneva Convention protocol. New caliber means new guns and convenient timing for aging inventory. Hence, the PDW projects came to pass. Interestingly enough, the idea of the PDW replacing the pistol in most conventional roles (like the M1 carbine's raison d'être) came up at this time and that influenced FN and H&K's mindset towards the PDW - the pistol was to be an afterthought and the longarm was to be the primary focus. Germany was one of the few countries to successfully implement this mindset with the MP7 being fielded for medics/cooks/etc. over a pistol. Funnily enough, these auxiliary troops eventually traded for G36s whenever possible while in A-stan. Well, NATO standardization never came through and every member state went a different path with pistol/PDW selection military-wise. All in all, short-barreled carbines all but replaced the 9mm SMG in all but the most niche roles (VIP protection - see the US Army's new APC9K, military police, very limited SF use). Pistols remained in 9mm, albeit somewhat modernized. You're right, it's true that European LEOs still use the SMG/PDW extensively, but it isn't because of any cooperation with NATO. All LEOs basically benefit from military R&D because they don't have to pay for it. Post-trials, the new products just showed up in the FN and H&K catalogues sent to acquisition departments and some LEOs gained interest and bought them. Hence, the P90 and MP7 in LEO units. Why European LEOs went with SMGs/PDWs over intermediate-caliber carbines is beyond me, but my best guess is that they tend to produce a lower profile than assault rifles and are therefore less threatening. In Europe, the image/optics of the LE officer is a big deal and a sensitive topic given the history of "secret police" and paramilitaries in the continent. Mind you, assault rifles do exist in Euro-LEO inventory, but they're just hidden out of sight until SHTF (see the police response in the 2015 Paris attacks). And, yes, you are also correct to point out that European militaries are more involved in domestic policing work than the US (Germany is a big exception). However, any similar use of weapons between military and police is purely coincidental. Their weapons are not funded, issued, or utilized in the same way. Mind you, military police (MPs) never do the job of civilian police - they strictly exist to protect military assets like bases. Military units deploying domestically are typically reservists adding additional security to an area temporarily, and in extra-ordinary circumstances. Domestic SWAT, CT teams, and area-security teams, though they may have arrangements for limited training with the military, are primarily trained *not* to kill unless necessary, which greatly differs from military doctrine. If a military wants to deploy troops domestically, it will do so with it's own funding, logistics, and training separate from the police. This goes for all NATO militaries. The distinct separation of military and police, as well as purely civilian legitimate control of said military and police, is actually one of the very many requirements for any new nation wanting to join/stay in NATO (well, you at least have to promise it within a certain timeframe, but that's another topic). An appendage about military vs LEO training for PDWs: I found that many LEOs are ordered to shoot them in single-shot at first contact and to go full-auto in emergencies. In fact, many P90s (well, PS90s at that point) and MP7s in LEO hands are semi-auto only. Contrast that with military training: the Bundeswehr trains to shoot MP7s in FA bursts to the chest/head area. DEVGRU SEALs, according to Mark Owen, go further and train to dump the entire 40rd mag into one, single guy on FA. For SF use, the MP7 is deployed suppressed for taking out a single sentry, guard dogs, lights, tires of getaway vehicles, and, according to Owen, mowing down bad guys in one room without waking up the others in the next room. If the cops do that to fellow citizens, there will be hell to pay (we're talking criminal charges). So that's the LONG story of PDW usage in military/NATO vs Euro-LEOs. As a personal note, I see the utility in the PDW, but I have serious doubts over whether it has a future as it stands today (with 5.7mm and 4.6mm), especially with hard armor (steel/ceramic/etc. at Level IV or better) becoming more prevalent in the commercial market and from hostile countries. I would recommend everyone check out the NATO trial report 9-Hole posted in the description for more details.

In a pistol length barrel the 5.56mm cartridge expends a lot of its energy making flash and noise meaning it will blind its shooter at night and tend to make them disorientated and deafened after firing just a few rounds. This weapon then puts all that blast 6-8" from the shooter's face so every round fired will make you feel like you got punched in the face. I suspect it failed because shooting it is an awful experience that makes the shooter brown out pretty fast. *Edited for spelling and grammar.

@@SurmaSampo Yes, I think you must be right. But there is no option to make it more convenient to shoot? Maybe using sound suppressor or something like that?

@@Cuccos19 Use less powder, faster burning powder, a heavier slug, a longer barrel, or some combination of the above.

@@muninrob But at that point, you are back to having logistical issues with specialized ammo. The whole point of the MDR exercise was to have a PDW in P90-ish form factor that fires standard 5.56 mm NATO rounds. Hell, apparently in "Iraqistan", most people who got issued pistol never got 9 mm NATO ammo for it. So chances are, the rear line troop in the alternative timeline who got issued MDR would have to shoot M855 just like everybody else, and they have the extra privilege of getting punched in the face by the propellant gas every time they shoot.

@@BicyclesMayUseFullLane If you rule out changing the ammo, you'll need a longer barrel. That would probably mean a bullpup design if you still want to fit the form factor. Myself I'd prefer faster burning powder pushing a heavier bullet, but I lack the engineering / math skills to figure out what it would do to the chamber of currently used 5.56 weapons. (probably make that M16A2 you were unlucky enough to draw blow up in your face, or throw the bolt through your head) In my experience (US Army H-60 crew), ammo for the M9 grew on trees, it was the 5.56, 7.62, .50 BMG, and 40MM that we had a hard time requisitioning enough of to even keep everyone qualified. (Thanks USMC 3rd ID - your "leftovers" got us qualified, our requisition arrived 2 months after y'all left)
