Unlocking Performance: The Power of Hornady Superformance Technology

At the heart of this ammunition's superior performance lies Hornady's revolutionary Superformance propellant technology. Unlike traditional ammunition, Superformance achieves its impressive velocities without compromising other critical performance aspects.

What Makes Superformance Ammunition So Effective?

Hornady’s engineers developed a proprietary blend of progressive propellants that deliver significant ballistic improvements. Here’s how it benefits you in the field:

• Increased Muzzle Velocity: Experience muzzle velocities up to 200 feet per second (fps) faster than conventional ammunition, without an increase in chamber pressure. For the 165 gr GMX 300 WSM load (Hornady Item 82206), this means an impressive muzzle velocity of approximately 3100 feet per second.
• Flatter Trajectories: Higher velocities translate directly to a flatter bullet path. This simplifies aiming at various distances, reduces bullet drop, and increases your effective range, giving you a distinct advantage on long shots.
• Enhanced Energy on Target: With increased velocity comes greater kinetic energy. The Hornady Superformance 300 WSM 165 gr GMX delivers a formidable muzzle energy of around 3519 ft-lbs, ensuring potent knockdown power and devastating terminal performance on game.
• No Compromises: Crucially, this velocity boost is achieved without increasing felt recoil, muzzle blast, or temperature sensitivity. This means you get magnum-level performance with the comfortable shooting experience you expect from your 300 WSM rifle. Barrel life is also preserved, as the higher velocities are not due to excessive pressure.

The GMX® Bullet: A Monolithic Masterpiece for Modern Hunting

Central to the effectiveness of this Hornady load is the 165-grain GMX (Gilding Metal eXpanding) bullet. This isn't just any hunting bullet; it represents the forefront of monolithic projectile design.

Key Design Features and Construction:

• Monolithic Gilding Metal Alloy: The GMX bullet is crafted from a single piece of gilding metal, a copper alloy, making it completely lead-free. This ensures environmental compliance and peace of mind for hunters.
