A Bit of Background

The.357 Magnum, on the other hand, is a larger, more powerful, and more energetic cartridge, with a maximum effective range of about 150 yards (137 meters) and an effective energy of about 550 foot-pounds (746 Joules).
Difference in Cartridge Length and Case Design
One of the main reasons.38 Special ammo will not fit into a.357 Magnum is due to the significant difference in cartridge length and case design. A standard.38 Special case measures 0.86 inches (22 mm) in length, while the.357 Magnum case is 1.29 inches (33 mm) in length. Additionally,.38 Special cases have a wider and shorter design compared to.357 Magnum cases. The longer case of the.357 Magnum allows it to handle the larger and more energetic propellant charges, making it more suitable for semi-rimless cartridges that generate higher velocities.
