Now, what does that mean? Therefore, be very careful not to mix any child cartridges with the parent cartridge. Another solution is to use an unjacketed soft lead hollow-point bullet as found in the FBI Load. The best-case scenario is needing to buy a new gun; the worst case scenario is having to buy a new gun and a hospital bill. use practically the same diameter bullets which punch holes that are pretty much the same size Can a .38 Special shoot .357 Magnum? Britain would later adopt the .38/200 as its standard military handgun cartridge. Except for case length, the .38 Special is identical to the .38 Short Colt, .38 Long Colt, and .357 Magnum. The .38 Special was introduced in 1898 as an upgrade to the .38 Long Colt during the Philippine–American War. It is used for target shooting, formal target competition, personal defense, and for hunting small game. It was about this time I bought my first magnum sixguns, namely a 4-5/8″ Ruger .357 Flat-Top Blackhawk and a 4″ Smith & Wesson .357 Highway Patrolman. In other words, 5.56mm is essentially .223 Remington +P. The best-case scenario is that the shooter has errantly chambered a round that can safely headspace in the gun, but the projectile is smaller than the bore diameter. The same is true for .308 Winchester and 7.62x51mm NATO and for the same reasons. In this case, the projectile will leave the barrel at a very slow velocity as most of the gas has already gone out of the barrel. Thirdly by not taking chances based on what people tell you. That said, .357 Magnum also has double the chamber pressure of .38 Special. There is more than one caliber/cartridge that will headspace and therefore will fire. .38 Special +P. But I carry Federal 148 gr wadcutters in standard velocities. A request for more powerful .38 Special ammunition for use by Air Police and security personnel resulted in the Caliber .38 Special, Ball, PGU-12/B High Velocity cartridge. [20] Issued only by the U.S. Air Force, the PGU-12/B had a greatly increased maximum allowable pressure rating of 20,000 psi, sufficient to propel a 130-grain FMJ bullet at 1,125 ft/s (343 m/s) from a solid 6-inch (150 mm) test barrel, and about 950–980 ft/s from a 4-inch (100 mm) revolver barrel. 5.56mm NATO has a slightly chamber design (meaning the chamber of the gun) and is loaded to higher pressure, but the case, projectile and all exterior dimensions are the same. Revolvers universally headspace on the rim, and the .38 Special and .357 Magnum have the same rim diameter, case diameter and projectile diameter. That is what LEO's carrried back in the revolver days and is quite effective from a 2" snubby. - Knowledge Glue", "The Colt Official Police: 61 years of production, 99 years of service", "FEDERAL Premium - 38 Special High Velocity (+P+) (image)", "Federal Ammunition - 38 SPL 148GR LEAD WC MATCH", Ballistics By The Inch .38 special results, ".38-44 HV: The Original Magnum - revolver round". The Taurus line is not, but the S&W Governor IS made to accept moon clips, so .45 ACP can be used in those as well.

[22][24] The FBI Load was later adopted by the Chicago Police Department and numerous other law enforcement agencies. You can use the bigger gun to fire the smaller bullet, but not the reverse at every level. This American pistol is the most common police service revolver in the world." Any planet.
