Rim diameters of 9mm Luger ammunition in the author's possession ranged from 0.387 to 0.390 inches, so the proposed 0.380 rim diameter is within 0.007 to 0.010 inches and should not require extractor adjustment except in exceptional cases. But when the cartridges are placed along side their peers, the shape of the 9mm Luger's taper becomes obvious by producing a gap between the rounds at the case neck. This is an example of another single column pistol where the straight-walled 9mm Automatic provides a higher cartridge angle, which dramatically reduces nosedive and produces an empirical improvement in feeding reliability. Notify me of follow-up comments by email. Actual rim width varies somewhat in all examples. These results show the clear superiority in feeding reliability with the straight-walled rimless 9mm Automatic. The 9mm bullets (projectiles) come in a variety of styles for specific purposes. This figure shows a prototype 9mm Automatic cartridge along with a 9mm Luger cartridge. The 0.0075-inch tapered cases show a difference in feed angle of up to six degrees (round 6) from the 9mm Automatic. C'est à ce jour le calibre d'arme de poing le plus largement répandu au monde, notamment comme munition d'arme de poing standard de l'OTAN. If you’re seeking tremendous energy, the.375 Magnum, 10mm Auto, and.45 ACP (to name a few) are usually the better choice. Luger never anticipated a single-stack? The least amount of taper (0.0037) showed a feed angle similar to the 9mm Automatic. Featuring reasonable accuracy as well as moderate recoil, the 9 x19mm round proves to be a solid choice for a wide range of shooting purposes. This condition permits maximum nosedive, which allows for an evaluation of the effect of different cartridge dimensions on feed angle. The prototype cartridge was made by trimming the Lapua cases to 9mm Luger length of up to 0.754 inches in length. peut ton prendre les bas tarifs ? This figure shows a prototype 9mm Automatic cartridge along with a 9mm Luger cartridge. I have never seen an actual Luger – are they all double-stack? Thanks for writing it. This is why the “9mm Luger” name was established, although it’s often now shortened to “9mm”. In this article we’ll take a look at their differing characteristics and why you might want to choose one or the other. The angle of the tapered cartridges was adjusted in order to show the angle of the cartridge's central axis. Even the 9mm Automatic (.38 Super Lapua) cases did not have rims perfectly concentric with the case body, and some rim drag could be felt by this method. The bullets were a Winchester 9mm 115-grain JHP seated to 1.115-inches, and a Speer 125-grain .357 SIG Gold Dot Hollow Point (GDHP) seated to 1.070-inches. The nosedive angle of the top round in a fully loaded six round DB9 magazine with a tapered 9mm Luger and a straight-walled 9mm Automatic is shown below. Feeding reliability with two hollow point bullets in the 1911 pistol. Video frame grabs showing cartridge angle before slide engagement and after slide engagement just before the cartridge nose contacts the feed ramp. The 0.006-inch rim, with its intermediate feed angles, had problems only with the wide-nosed Speer .357 SIG GDHP. Accurate Arms has data for .30 Luger under a SAAMI maximum of 28,000 cup. The plotted values are the cartridge angle relative to the magazine feed lips. Taper increases a problematic behavior called nosedive. Shooting a .22 LR rifle at 300 yards is just as challenging as shooting a .300 Win. Frank Barnes (2006) notes that it is the most widely used cartridge in the United States. The straight-walled 9mm Automatic produces no gap. Now let me add a little something about 9mm vs .45. The .38 Super Lapua cases I used were truly rimless with the same rim and case wall diameter. Good article! To get started, click the link below to visit mymagnow.com and learn how to access your digital magazine. Legendary gunmaker, George Luger, introduced the 9mm round after the .38 Special, way back in 1902. All Shooting Times subscribers now have digital access to their magazine content. With the abundance of these pistols produced today, especially for the self-defense market, maximizing reliability is a compelling argument for its creation. Not all 9mm Luger ammunition has the same amount of taper. ALL RIGHTS RESERVED. I wonder about the trajectories of the different rounds, which shoots flatest for longest? Le Luger de 9 mm, également connu sous le nom de Parabellum 9X19 mm, a été conçu par George Luger. The 1911 magazine was fully loaded with 10 rounds. Yes 9mm & 9mm luger are the same. The rim of the new 9mm Automatic will necessarily be smaller than the 9mm Luger, but not by much. The feed angles correlated with their feeding reliability. Let us look at several of the popular options. The difference in the shape of the case is not obvious, because the 9mm Luger's taper is slight. For the “artillery” models there was the optional 32 round “snail” drum magazine. The feed angle with the two different bullets was very similar, so the lines are the average of the two bullets. Nosedive is an inherent problem in most single stack magazines. To make a comparison, a 9mm NATO round would be like a 9mm +P round in terms of pressure. Developing fast 9mm handloads is not for beginners, but it can be done safely if attention is... Give a Gift   The 9×19mm Parabellum, 9mm Parabellum, or 9mm Luger is a firearms cartridge that was designed by Georg Luger and introduced in 1902 by the German weapons manufacturer Deutsche Waffen- und Munitionsfabriken (DWM) (German Weapons and Munitions Factory) for its Luger semi-automatic pistol. Shouldn’t it be a little shorter,I mean it’s 2mm? This is an artifact of it being a 10 round capacity magazine, as this improvement was not evident in a 15 round single column magazine that was tested. It was developed by a German named Georg Luger in 1902 and was manufactured for the Luger semi-auto by DWM or Deutsche Waffen- und Munitionsfabriken. Let’s Look At 380 ACP vs 9mm Luger. Alleged Shooter of 8-Year-Old Atlanta Girl Secoriea Turner Has Been Charged With Murder [VIDEO], Things That Don’t Suck: Trader Keith’s Rifle Strap, Culling Belt and Cartridge Slide, How I Ended My Search for the Perfect Everyday Carry Pistol, Improve Your Shooting: 50-Round Skill Sustainment Course of Fire. I pay between $9-$15.00 pr box. 9mm Auto vs. 9mm Luger - Which is Better? We're taking a look at what the Army's Elite Units are using for service rifles and what the future of SOCOM sniping looks like. 9mm vs .40 Caliber: Reasons I Don’t Carry a .40 Smith and Wesson. Thus, a true rimless case offers the best feed angle. Also, some shooters (including the author) use .38 Super magazines in their 9mm Luger 1911 pistols. Made worse when trying to run even weaker than regular off the shelf low velocity, reduced recoil, or a combination thereof rounds through those guns. The test gun was a custom-built Caspian single column 1911 pistol with a ramped 9mm Luger barrel. Cartridge feed angle was measured from high-speed (1000 frames per second) video. It is by far the most practical solution to overcome the flaw of the tapered 9mm Luger design. Worse, if it doesn’t achieve the minimum, FTE city. One hundred and twenty rounds (0.0015 N=30 Hornady 9mm Steyr; 0.0025 N=30 Hornady 9mm Steyr; 0.006 N=30 Starline .38 Super Comp; 0.020 N=30 Starline .38 Super +P) were video recorded and analyzed for feed angle and compared to the 9mm Automatic data. In the figure below, the feed angle of the 9mm Automatic (black line) is at the top of the other lines at nearly every point, indicating a consistently high feed angle. Presumably, when the magazine spring is near full compression, the pressure can affect the feed angle of tapered cartridges. I tested two different flat nose bullets with three different cases for feeding reliability. Loads with 9mm Luger brass with the Winchester JHP bullet averaged 0.0068-inches taper and for the Speer .357 SIG GDHP bullet 0.0065-inches taper. The .0037- and .005-inch taper cartridges were made with once-fired 9mm Automatic brass. Test results showed that wider rims produce lower feed angles (see slideshow). One hundred and eighty rounds were video recorded for this comparison (three full 10-round magazines (N=30) each for six conditions: three types of brass X two bullets). The least amount of average taper was 0.0065-inches and the most was 0.0135-inches. However, they have slight rims that measure about 0.006-inches wider than the case body. You could smell the gunpowder. It can be referred to as the “9mm Parabellum”. Same is true of any other SAMMI or CIP approved round. Feeding, extraction and ejection were flawless. They were around from 1985 to 1999 in 9mm and 45acp. Bullets included round nose, 9mm hollow point and .357 SIG designs. As the round is pushed forward, a rim wider than the case wall will drag on the underlying cartridge once it moves past the extractor groove. Some of the finest handguns in the world are chambered for the 9mm Luger cartridge. “Authorities”, a.k.a. Il s'agit de la cartouche pour arme de poing militaire la plus populaire et la plus utilisée. Same plotting method as previous figure. Sig Sauer 9mm versus 380. When loaded in straight-walled cases, the wide-nosed .357 SIG bullet has a significant margin of clearance and feeds 100% of the time. Is there a difference? When loaded, the prototype cartridge will be referred to as the 9mm Automatic (9mm Auto). True imports, those models never initially engineered, nor re-engineered for the US market have problems with this. The 9mm Luger cartridge is flawed. This also shows the dramatic improvement in feed angle offered by the 9mm Automatic. Taurus G2c … It surprised me a little, in the early 1990s, that the US and UK had different ideas on what a “9mm” (by which I assume you mean the widely-used 9mm x 19 Parabellum) was. By all accounts, 9mm Luger is the world’s most popular and widely used cartridge for pistols and submachine guns. Le 9 × 19 mm Parabellum est un calibre de cartouche destinée aux pistolets semi-automatiques. He could have also chosen to head space on the case mouth like .45ACP, which is also ‘rimless‘. But really, in the past 40 years the ammunition options and military surplus availability have pretty much ruled out reloading for me. The difference in angle can be quite large, up to over seven degrees (round 5) with the most tapered brass (0.0133). Handgun Ammunition: What Is The Difference Between 9mm and 9mm Luger? Thus, 9mm NATO is an overpressure variant.”. In this example, the 9mm Luger cartridge's feed angle (After) was 13 degrees below the angle of the magazine's feed lips. Comparaison .45 ACP vs 9mm. This matches the 0.380 maximum SAAMI dimension for the 9mm Luger case mouth. The pressure is mild vs 9mm in the same action, total recoil is mild, the power factor is below IPSC Minor. 1 thought on “The Best 9mm Carbine: The Complete Buyer’s Guide” mike. This occurs because the nosedive gap gets bigger as more rounds are loaded in the magazine regardless of taper. “The standard 9mm NATO round is a 124-grain FMJ, loaded to 36,500 psi, which is a bit hotter than the CIP standard of about 34,000 psi. Mr. Hoober – thank you for the information, clear and concise. The last table shows the proposed dimensions and actual measurements from 9mm Luger ammunition for comparison. There is some debate about this, technically the 9mm should head space on the case mouth, but I know when the taper is not right it will not operate properly. We ping steel with a .300 WinMag at over a mile. ISS Prop House gives us the rundown on the guns used in Enemy at the Gate. It is chambered in handguns, submachine guns and rifles, and is the standard NATO round for handguns. .38 Comparaison spéciale vs 9mm. Reflects directly on what I said above. I selected cases with a rim of .0015-, .0025-, .006- and .020-inches wider than the case body. But in this comparison, the 9mm Luger clearly has higher energy ratings.
