Why Solid Copper Ammo Matters: Benefits for Defense & Range Shooting

Feb 6th 2026

In a market saturated with lead-based bullets, Defiant’s solid copper ammunition stands out. These bullets deliver deep penetration and consistent weight retention due to their monolithic copper construction, while eliminating lead fouling.

For self-defense, our Total Copper X-panding (TCX) bullets expand reliably at multiple velocities, meeting FBI standards and transferring energy to the target instead of shedding fragments. On the range, our affordable FMJ loads use the same lead-free copper design to deliver clean shooting, extended barrel life, and precision accuracy.

Choosing lead-free copper isn’t just about performance; it also meets restrictions at indoor ranges and reduces environmental impact. With Defiant Munitions, shooters get confidence and consistency whether they’re training or protecting their loved ones.
