Grain Weight: 129 Grains

The 129-grain projectile weight is a meticulously chosen balance for the 6.5 Grendel. It strikes an optimal equilibrium between downrange energy, velocity, and ballistic coefficient, making it a highly versatile and effective bullet for various scenarios.

• For Hunters: This weight provides ample energy transfer for effective and ethical harvesting of medium-sized game like whitetail deer, wild hogs, antelope, and even some smaller elk. It ensures deep penetration and reliable expansion upon impact, leading to clean, humane kills.
• For Target Shooters: The moderate weight contributes to excellent long-range stability, minimizing the effects of wind and maximizing accuracy. It's heavy enough to resist atmospheric disturbances but not so heavy as to drastically reduce velocity, allowing for precise shot placement.
• Ballistic Sweet Spot: The 129-grain SST bullet boasts an impressive ballistic coefficient, allowing it to maintain energy and velocity over extended distances. This is critical for precision and ethical hunting, as it reduces bullet drop and wind drift, simplifying complex long-range shots.

Quantity: 20 Rounds Per Box

Each box contains 20 rounds, a standard and convenient quantity for both range sessions and preparing for a hunt. This packaging makes it easy to purchase sufficient ammunition for zeroing your rifle, practicing fundamental shooting skills, or stocking up for a hunting trip without over-committing to large bulk purchases initially. For competitive shooters or those who spend significant time at the range, acquiring multiple boxes is a common and practical approach.

Muzzle Velocity: 2238 Feet Per Second (FPS)

A muzzle velocity of 2238 FPS for a 129-grain bullet in the 6.5 Grendel platform is an excellent balance, optimized for this cartridge's design. This velocity ensures:

• Flat Trajectory: The initial speed helps the bullet maintain a flatter trajectory out to moderate distances, simplifying holdover calculations for shooters and making hits easier at varying ranges.
• Consistent Performance: This specific velocity is engineered to allow the SST bullet to perform optimally, initiating reliable expansion upon impact while retaining sufficient energy for deep penetration. It's a critical factor in achieving clean, humane kills on game.
• Reduced Time of Flight: A higher velocity means less time the bullet is subject to external forces like wind, contributing to better accuracy at range, especially when conditions are challenging.

Muzzle Energy: 1435 Foot-Pounds (Ft-Lbs)

Muzzle energy is a critical metric for hunting, indicating the power the bullet possesses at the moment it leaves the barrel. 1435 ft-lbs of muzzle energy is more than sufficient for hunting medium-sized game animals and ensures effective energy transfer downrange.

• Terminal Performance: This energy ensures that the bullet can deliver a devastating blow to the target, facilitating rapid incapacitation and ethical harvests. It's a key indicator of the ammunition's effectiveness in the field, ensuring the bullet does its job reliably.
• Kinetic Transfer: Coupled with the SST bullet's design, this energy translates into significant kinetic transfer upon impact, creating a larger wound cavity and ensuring vital organ damage, which is paramount for humane hunting.

Bullet Style: Polymer Tip (SST - Super Shock Tip)

The Hornady SST bullet is a marvel of projectile engineering, designed for maximum expansion and devastating terminal performance across a wide range of velocities.

• Aerodynamic Design: The sleek polymer tip not only significantly improves the bullet's ballistic coefficient (making it more aerodynamic and less susceptible to wind drift) but also initiates rapid and controlled expansion immediately upon impact, even at lower velocities.
• InterLock Ring: A key feature of the SST is the Hornady InterLock ring, which mechanically locks the core and jacket together. This critical design element prevents core-jacket separation during expansion, ensuring maximum energy transfer and bullet integrity as it penetrates the target, even through tough hide and bone.
• Secant Ogive Profile: This optimized profile, combined with the polymer tip, results in a flatter trajectory and less wind drift, making it easier to hit targets at longer distances with predictable results.
• Reliable Expansion: The SST is engineered to expand reliably across a wide range of velocities, making it highly effective whether shots are taken close-up in dense woods or at extended ranges across open fields. This versatility is crucial for hunters who might encounter various shooting scenarios.

Lead-Free: No

This ammunition contains traditional lead components. While many jurisdictions are moving towards lead-free requirements for hunting, this traditional lead-core design offers proven performance, consistency, and often greater cost-effectiveness in areas where lead ammunition is permitted. Always check local and state regulations before hunting or shooting, as restrictions on lead ammunition are becoming more common in certain regions.
