Do copper bullets fragment less than traditional lead?

Copper’s Properties and Their Impact on Fragmentation

Copper bullets are often compared to traditional lead bullets due to their similar density and weight. However, copper has a higher Young’s modulus, which is a measure of a material’s ability to resist deformation under stress. This property allows copper bullets to resist fragmentation and maintain their shape, even when subjected to the high pressures generated by a rifle’s firing mechanism.

Monolithic Copper Bullets: A Solution to Fragmentation

Monolithic copper bullets are made from a single piece of copper, which reduces the likelihood of fragmentation. These bullets are often used in hunting applications, particularly for large game, as they tend to produce cleaner kills with less tissue damage. When selecting a monolithic copper bullet, it’s essential to consider the bullet’s weight, diameter, and the rifle’s chamber pressure.

Real-World Testing and Results

Studies have shown that copper bullets can penetrate up to 25% deeper than traditional lead bullets at the same velocity. This is because the copper’s higher density and strength allow it to maintain its shape and resist fragmentation. When tested at 1,200 feet per second, copper bullets demonstrated a 30% reduction in fragmentation compared to lead bullets.
