Will 0.05" make a big increase in pressure to be unsafe? Posted on February 19, 2021 by February 19, 2021 by 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 … 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. A higher pressure limit, referred to as +P (plus pressure), is 38,500 psi. 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. I believe that the tapered chamber in common use is actually a manufacturing expedient. Posted February 19, 2021 by. A pistol that is rated for 9mm is rated for 9mm-like chamber pressures. 9mm Shotgun Adapters As a general rule, the longer the adapter, the more FPS it produces. 9mm, was originally designed by … Trying to push your reload any stronger exceeds the design limits of the ammunition components and gun. 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. Anyone loading 9mm for their 1911? Not to impressive when standard 124 grain 9mm is often 1150fps and 1200fps for +P ammo. Do you have to load the 9mm slow to shoot well at 50yd like the .45acp?-Trevor 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. 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. Compatible with Single as well as Double Barrel Break Action Shotguns. 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. I have to believe a chambers dimensions is the primary factor affecting pressure, using identical ammo. Clamped over this hole is a closed tube with a free-moving piston (Figure 3.1). 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). The 6.5 Creedmoor also has a slight power advantage. Reloading Data Center. Perhaps the hotter CCI's take the pressures up into the SAAMI max range in order to achieve their higher velocities. The use of cartridges that produce too much chamber pressure is also discouraged. The earliest was the 9mm Luger originally designed for George Luger's famous pistol, @ Up to 35,000 psi. The measurement of maximum chamber pressure is carried out with a 'pressure gun'. 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. The original chamber is stepped rather than actually tapered. Mean pressure cannot exceed 37k PSI and 230MPa. Uncategorized can you shoot 9mm out of a 38 super. Rifled with a 1:12 twist rate. Your Body, Your Birth, Your Baby, Your Life. Length of barrel affecting chamber pressure doesn't make any sense. Although the pressures for 9mm NATO are listed higher than standard 9mm ammo, the NATO velocity often doesn't live up to the hype. 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. Yes, the .38 Super and 9x23mm Winchester will chamber in most 9mm Largo firearms, and if they will chamber they will fire.

The MAX load pressures shown by Hodgdon match the industry standards, just as the ammunition loading companies do in factory loads. Energy must be between 400ft/lbs and 600 ft/lbs. Series 117B conformal pressure sensors measure true gun chamber pressure directly through an unmodified shell case. Bullet Ballistics: CUP Precision must be at least 3″ at 50yds. 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. The metallurgy and design of the Destroyer Carbine was not developed to handle the pressure of these rounds. There is also a +P+ load, but there is no prescribed limit for it. This is a very strongly built action and barrel with a hole drilled into the top of the chamber. German military pistols have the stepped chamber. Dad is former army but enlisted as a medical officer and didn’t care for his experience with the M9. Neither are democrats btw. This method involved a sensor with a machined curved diaphragm that measures pressure directly through the shell case. Antenatal Course Packages; FAQ’s; Terms and Conditions If you are interested, here is an excellent website that gives a good idea of fps per inch BBTI. Rifle Chamber Pressure Testing Hardware & Software PressureTrace II ™ is a single channel high-speed physical event data acquisition system that captures changes to pressure inside your rifle chamber in real time. 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. 9mm 410 Shotgun Adapters Allow a 410 Shotgun to use 9mm Auto as well as Luger Ammo. The metallurgy and design of the Modelo A were not developed to handle the pressure of these rounds. It burns faster in higher pressure environments (such as in a firearm’s chamber). The 9×19 Parabellum, a.k.a. However, with low-pressure rounds such as the 45 colt, the fps difference is minimal once past the 11″ length. 9mm Shotgun Adapters for 410 Shotguns. The 9mm Luger (9x19m) round measures 0.355 inches in diameter, while the .38 Super ( 9x21mm) round measures .356 inches. 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. All dimensions are in millimeters. There is a reason why this is called a MAX load – because it is! Bullet weight must be between 108gr and 128gr. There's an upper limit to safe chamber pressure, so usually more bullet weight = … OK, this is pretty encouraging. Based on this success, the conformal sensor became a SAAMI/ANSI “National Standard” for ammunition testing. The pressure was upped 10% to create the 9mm parabellum for sub machine guns during WWII . 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. The standard maximum average pressure limit established by SAAMI is 35,000 psi.

Granted, overpressure ammunition is also a thing, and 9mm +P and +P+ can add a bit more zing at the cost of more pressure. In my case, a 9mm fits into a category of higher chamber pressure and a supported barrel is required, yes? 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. 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. Most pressure curves I've seen for black powder show peak pressure in about 90 - 125 microseconds, vs. smokeless in 150 - 250 microseconds. From what I have seen it most often is in the 1150-1180fps range from a 4" barrel. Also, the moving piston must be brought to a halt, which skews a reading in the opposite direction.
