The metallurgy and design of the Destroyer Carbine was not developed to handle the pressure of these rounds. In the case of, say, 9mm it's about 34,000 psi, in the case of .45 ACP it's about 21,000 psi and in the case of .30-06, God's own rifle cartridge, it's around 60,000 psi. The measurement of maximum chamber pressure is carried out with a 'pressure gun'. The 9mm is versatile and can be loaded to higher pressures for more speed and power for situations that call for it. 9mm, was originally designed by … Happened today, my folks decided they wanted to shoot. Go refer to the SAAMI booklet (which you actually referenced in our last back-and-forth) and tell me what the established max average pressure is for each cartridge (9mm and 9mm +P). Also, the moving piston must be brought to a halt, which skews a reading in the opposite direction. The MAX load pressures shown by Hodgdon match the industry standards, just as the ammunition loading companies do in factory loads. Trying to push your reload any stronger exceeds the design limits of the ammunition components and gun. Bullet weight must be between 108gr and 128gr. Length of barrel affecting chamber pressure doesn't make any sense. If you are interested, here is an excellent website that gives a good idea of fps per inch BBTI. Heavier bullets also add more pressure to the chamber when fired. I have to believe a chambers dimensions is the primary factor affecting pressure, using identical ammo. I know I'm pretty close to SAAMI minimum spec for 9mm … Cherish You; About; Antenatal. From what I have seen it most often is in the 1150-1180fps range from a 4" barrel. Posted on February 19, 2021 by February 19, 2021 by Please make certain your handgun is designed to handle that boosted chamber pressure before firing this ammo in it. Series 117B conformal pressure sensors measure true gun chamber pressure directly through an unmodified shell case. 9mm Shotgun Adapters As a general rule, the longer the adapter, the more FPS it produces. 9mm 410 Shotgun Adapters Allow a 410 Shotgun to use 9mm Auto as well as Luger Ammo. The use of cartridges that produce too much chamber pressure is also discouraged. Here is an extract from the actual 1913 German military blueprints for the 9mm Parabellum (P.08 Luger) pistol. Hornady specified, and SAAMI approved, a maximum average chamber pressure (MAP) of 62,000 psi. German military pistols have the stepped chamber. Clamped over this hole is a closed tube with a free-moving piston (Figure 3.1). The 9mm is a rimless cartridge that operates in about the 33,500 to 34,000 PSI range in most loadings, while the .38 Super is a semi-rimmed cartridge that operates in the same pressure range and has a non-tapered case. The 9×19 Parabellum, a.k.a. Most pressure curves I've seen for black powder show peak pressure in about 90 - 125 microseconds, vs. smokeless in 150 - 250 microseconds. I believe that the tapered chamber in common use is actually a manufacturing expedient. Precision must be at least 3″ at 50yds. Glock’s 9mm pistols can handle +P ammo, as can S&W’s Shield pistols. The original chamber is stepped rather than actually tapered. This website uses cookies to improve your experience while you navigate through the website. Uncategorized can you shoot 9mm out of a 38 super. I have a handsome custom rifle on the Krag action built by Griffin & Howe during the 1930s, and it is chambered to .22 Hornet, which is commonly loaded to 47,000 c.u.p. When Remington submitted the .260 for SAAMI approval, it requested—and SAAMI approved—a 60,000 psi … So my question is, is it safe to reseat the bullets to 1.005" from 1.055" without any overpressure issues seeing that TiteGroup is a fast powder already. The 9mm is undeniably more popular than the.38 Super in North America, while the.38 Super remains popular in comp Based on this success, the conformal sensor became a SAAMI/ANSI “National Standard” for ammunition testing. I've read that SAAMI lowered the maximum chamber pressure for .357 Mag because manufacturers were putting out smaller .357s - even with new materials like scandium and titanium, a J-frame probably isn't as strong as a steel N-frame. OK, this is pretty encouraging. The 9mm x 19mm cartridge comes in several variants. Anyone loading 9mm for their 1911? The earliest was the 9mm Luger originally designed for George Luger's famous pistol, @ Up to 35,000 psi. Given that maximum pressure is in the chamber and it drops pretty dramatically as the bullet travels down the barrel, and due to the way AR barrels have to be built simply to fit, the flutes wouldn't even start until about 3" from the bolt face. Maximum recommended chamber pressure for the Model 1898 Krag in .30-40 caliber is 40,000 c.u.p. Rifled with a 1:12 twist rate. can you shoot 9mm out of a 38 super. 9mm Shotgun Adapters for 410 Shotguns. Posted February 19, 2021 by. The standard maximum average pressure limit established by SAAMI is 35,000 psi. Not to impressive when standard 124 grain 9mm is often 1150fps and 1200fps for +P ammo. Bullet Ballistics: CUP The 9mm Luger (9x19m) round measures 0.355 inches in diameter, while the .38 Super ( 9x21mm) round measures .356 inches. Mean pressure cannot exceed 37k PSI and 230MPa. This is a very strongly built action and barrel with a hole drilled into the top of the chamber. Do you have to load the 9mm slow to shoot well at 50yd like the .45acp?-Trevor The designer came up with a recipe to send a particular projectile downrange at a particular speed, which creates a certain amount of pressure inside the chamber. There is also a +P+ load, but there is no prescribed limit for it. A higher pressure limit, referred to as +P (plus pressure), is 38,500 psi. Find in stock 9mm Luger ammo deals for sale. With the riots he reconsidered. The software displays a high resolution rifle chamber pressure curve on your computer after each shot so you can compare the total energy delivered by a load, the … Reloading Data Center. STANAG 4090 has some basic requirements for NATO-compliant 9mm ammo that we care about: It’s got to be 9mm, and gives the dimensions as such. Although the pressures for 9mm NATO are listed higher than standard 9mm ammo, the NATO velocity often doesn't live up to the hype. The 6.5 Creedmoor also has a slight power advantage. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Yes, the .38 Super and 9x23mm Winchester will chamber in most 9mm Largo firearms, and if they will chamber they will fire. It burns faster in higher pressure environments (such as in a firearm’s chamber). Perhaps the hotter CCI's take the pressures up into the SAAMI max range in order to achieve their higher velocities. Unless the barrel is worn, the bullet is creating a gas seal as soon as it leaves the chamber so what is after the chamber would have little if any impact. A pistol that is rated for 9mm is rated for 9mm-like chamber pressures. Yes, the .38 Super and 9x23mm Winchester will chamber in most 9mm Largo firearms, and if they will chamber they will fire. Antenatal Course Packages; FAQ’s; Terms and Conditions In my case, a 9mm fits into a category of higher chamber pressure and a supported barrel is required, yes? Your Body, Your Birth, Your Baby, Your Life. Due to the longer cartridge and higher pressures, the pistol is slightly larger than the Glock 17, having a roughly 2.5 mm (0.1 in) greater width and 7 mm (0.3 in) greater length. The metallurgy and design of the Modelo A were not developed to handle the pressure of these rounds. The use of cartridges that produce too much chamber pressure is also discouraged. Though many small parts interchange with the Glock 17, with a close to 50% parts commonality, the major assemblies are scaled-up and do not interchange. Neither are democrats btw. There is a reason why this is called a MAX load – because it is! That means it is loaded to create more pressure in the chamber when it is fired, giving it a higher muzzle velocity and resultant energy on impact. All dimensions are in millimeters. Pounded by high pressures, crushers don’t register peak pressure accurately because the flow of copper is slower than the change of pressure in the chamber. Will 0.05" make a big increase in pressure to be unsafe? This method involved a sensor with a machined curved diaphragm that measures pressure directly through the shell case. The pressure was upped 10% to create the 9mm parabellum for sub machine guns during WWII . However, with low-pressure rounds such as the 45 colt, the fps difference is minimal once past the 11″ length. Granted, overpressure ammunition is also a thing, and 9mm +P and +P+ can add a bit more zing at the cost of more pressure. There's an upper limit to safe chamber pressure, so usually more bullet weight = … Compatible with Single as well as Double Barrel Break Action Shotguns. Energy must be between 400ft/lbs and 600 ft/lbs. From what I read, unsupported is only appropriate for standard .45acp loads. Compare prices from online vendors and choose the best deal.
