Description
Wilson Combat loads this 357 Magnum ammunition with Lehigh Defense's 125-grain Controlled Fracturing bullet, a purpose-built design that sets itself apart from conventional hollow points. The solid copper projectile features pre-stressed points that are engineered to fracture at a predetermined depth, causing the bullet to shed petals that create additional wound channels while the main shank continues straight through for penetration. This means you get initial energy transfer, multiple wound paths, and deep-penetrating performance all from one round.
What Makes the Controlled Fracturing Bullet Different
The Lehigh Defense technology differs from traditional expanding rounds that mushroom and can lose penetration. Instead of relying on a single wound path, the controlled fracturing design creates multiple channels of trauma. The solid copper construction also means these rounds are lead-free, making them suitable where lead ammunition restrictions apply.
Ballistics and Real-World Performance
The 125-grain load in 357 Magnum carries significant velocity and energy, delivering the kind of stopping power the caliber built its reputation on. Factory testing shows velocities around 1250 fps with approximately 434 foot-pounds of muzzle energy. This weight and speed combination has been proven effective for defensive purposes, and the specialized bullet design maximizes what that energy can do on impact.
Built for Reliability
Wilson Combat pairs these Lehigh Defense projectiles with quality brass cases to ensure consistent feeding and reliable performance. Each box contains 20 rounds packed for secure transport.

Frequently Asked Questions
What is the advantage of Controlled Fracturing bullets over standard hollow points?
Controlled Fracturing bullets use pre-stressed solid copper that deploys razor-edge petals at a predetermined depth, creating multiple wound paths while the core continues penetrating straight. This differs from traditional expanding rounds that mushroom and lose penetration. You get initial energy transfer, multiple wound channels, and deep penetration all from one design.
Can I use this ammunition in my revolver or semi-automatic?
Yes, 357 Magnum ammunition works in both revolvers and semi-automatic pistols chambered for 357 Magnum. However, note that the 125-grain Controlled Fracturing bullet has a flat point design that may not work as smoothly with revolver speed loaders compared to traditional round-nose or hollow-point bullets.
Is this ammunition suitable for defensive use?
The 125-grain 357 Magnum load with Controlled Fracturing bullets is specifically designed for serious terminal performance in defensive applications. The combination of velocity, energy, and bullet design provides reliable expansion and penetration characteristics that make it suitable for self-defense purposes.
Are these rounds lead-free?
Yes. Lehigh Defense's Controlled Fracturing bullets are manufactured from solid copper, making them lead-free ammunition. This makes them suitable for use in areas where lead ammunition restrictions apply.
