Slightly outta left field, here, but does anyone know what bullets killed the Maggiores? Were they 0.357s?
The bullets in SoCal were .38 but the gun used in D/S might've been a .357 using .38 ammo
Sometimes it seems like a miracle that this guy's gun went off all
This was done by S&W when they introduced the round in the 1930's to prevent people from chambering it in the many old .38 Special revolvers in use. Reason? The cartridge is loaded MUCH hotter. A standard pressure 125 grain JHP .38 will exit the muzzle at about 850-890fps. They also load .38 to "+p"pressures and these make maybe 920 -970 fps. Standard .357 mag rounds are loaded up to 1450 or so fps. (All velocity estimates are from a 4 inch barrel.) The .357 figure is the bullet diameter The .38 is the rounded up diameter of the cartridge case-into which the bullet is seated. All .357 Magnum revolvers chamber and fire .38Special ammo...but not the reverse.
Can a 9mm round be fired from a .38 revolver? It could be done as the diameter of a 9mm bullet is .356-virtually identical. But the 9mm, like all semi-auto rounds other than the .32 ACP is a "rimless" round. (No metal flange protrudes beyond the case at the rear.) The .32ACP is semi-rimmed and can be fired from .32 Spl revolvers-I have done it thousands of times. BUT the 9mm is rimless-put it in a .38 Spl chamber and it will bounce forward when you drop the hammer-and the primer will not light. So no bang.
You can fix this by filing out a small part of the chamber rear and then placing the 9mm rounds in a thing called a "moon clip." These were invented in WWI so revolvers could use the rimless .45ACP cartridge invented for the 1911 .45 automatic. Or you could put shoulders inside the chambers to support the round by the forward cartridge shoulder-but then you could not chamber anything else-.38 Spl rounds are longer than 9mm.
BTW.."ACP" stands for "Automatic Colt Pistol." The .32 ACP. .380ACP and .45ACP were all invented by John Browning in the first decade of the 20th century to chamber in new Colt pistols he designed with Colt. Nothing better has been invented since...(IMHO)
Browning did not stop there..the oldest weapon still widely used by the U.S. military is the Browning M2 .50 caliber machine gun. Adopted 90 years ago, in 2017 it is still mounted on every U.S. Navy ship and every Army/Marine Corps tank. Lucky is the infantry squad in Afghanistan with an M2 (aka Ma Duece) around.
The 9mm (aka 9mm Parabellum and the 9x19) was invented by Georg Luger in about 1902 and has been used by armies around the world since. It is now the most commonly used defensive pistol cartridge in the world. Our main bedroom gun is a pistol invented in 1911 chambered for a round invented in 1902!
The .357 magnum was invented as a special purpose LE round and a hunting round. it was adopted by the FBI in the 1930's but largely replaced by lighter .38 Spl revolvers in the 1940's. The .357 is not a good defensive round in actual use-its sound signature is almost 200% greater than the .38Spl. Its recoil is hard to control unless you shoot with it a lot. And the muzzle flash at night (say in a dark bedroom!) will blind you. Making yourself deaf and blind is not conducive to controlling a situation. The .38Spl was invented in 1898 and is currently the most popular revolver cartridge in the world.
EAR referred to his weapons frequently as a .357 magnum as it frightened people. (Remember the movie "Magnum Force?") But he used .38Spl ammo.
Well hope that helps..handguns and their ammunition can be confusing but not much has changed in that world for over 100 years. Refinement yes (especially better bullet design) but real change? No.
