The design dictates how each cartridge functions in terms of ease of use.
Bullet selection is crucial for any handgun cartridge. The 357 Magnum commonly uses bullets ranging from 110 to 180 grains, with 125-grain and 158-grain bullets being very popular. The 10mm frequently uses bullets from 155 to 220 grains. The heavier bullets in the 10mm contribute to its reputation for delivering more kinetic energy on target. The range of bullet weights allows shooters to select the best projectile for their chosen application.
Velocity is a key factor in understanding ballistics. In general, the 357 Magnum, with its heavier bullet weights, can achieve muzzle velocities ranging from 1,200 to 1,700 feet per second (fps). This depends on the bullet weight and the barrel length of the handgun. The 10mm can reach velocities of 1,100 to 1,400 fps, which also varies with bullet weight and barrel length. The velocity is a significant measure of a cartridge’s potential for hitting the target.
Trajectory is influenced by velocity and bullet design. The flatter the trajectory, the less the bullet will drop over distance. The 357 Magnum, with its flatter trajectory, is generally known to be more accurate over longer distances. The 10mm’s trajectory is slightly more pronounced, depending on the bullet weight. Understanding these factors allows shooters to predict how the bullet will impact the target at any given range.
