The .38 Special, with its .357-inch diameter bullet, is available in a variety of common bullet weights. Typical loads feature bullets ranging from 125 grains to 158 grains. The .38 Special offers respectable performance for the size of the cartridge.
.357 Magnum Bullet Diameter and Weight
The .357 Magnum shares the same .357-inch bullet diameter as the .38 Special, but utilizes a longer case. This allows for the use of significantly more propellant, resulting in dramatically increased velocities and energy levels. Bullet weights for the .357 Magnum typically range from 110 grains to 180 grains, with the heavier bullets delivering impressive energy.
9mm Bullet Diameter and Weight
The 9mm Luger features a bullet diameter of .355 inches. Common bullet weights range from 115 grains to 147 grains. The 9mm typically produces muzzle velocities and energy levels that fall between those of the .38 Special and the .357 Magnum.
The muzzle velocity and energy output of each round will vary depending on the specific ammunition used. However, we can illustrate the key differences. A typical .38 Special round firing a 158-grain bullet might achieve a muzzle velocity of around 800 feet per second (FPS), producing roughly 225 foot-pounds of energy at the muzzle. The .357 Magnum, in contrast, firing a 158-grain bullet, can easily reach 1250 FPS and generate over 550 foot-pounds of energy at the muzzle. The 9mm, firing a 124-grain bullet, might achieve approximately 1150 FPS, generating around 365 foot-pounds of energy at the muzzle. These examples demonstrate the marked power increase found with the .357 Magnum.
The trajectory of a bullet also plays a crucial role. A flat trajectory is preferable for longer ranges. Because of its higher velocity, the .357 Magnum generally has a flatter trajectory than the .38 Special. The 9mm offers a relatively flat trajectory as well, making it easier to aim and hit targets at various distances. The .357 Magnum’s increased velocity provides an advantage in terms of range.
The effective range of each cartridge will vary based on the firearm, the shooter’s skill, and the specific ammunition.
