Hornady 6.5mm 129gr SST Bullets

Hornady 6.5mm 129gr SST Bullets combine a secant ogive, polymer tip and InterLock construction for hunting. The .264″ bullet weighs 129 grains and has a .485 G1 ballistic coefficient with a .264 sectional density. As a result, it offers a practical balance of bullet weight, aerodynamic efficiency and controlled expansion.

Why Choose Hornady 6.5mm 129gr SST Bullets?

The secant-ogive profile helps reduce drag and improve aerodynamic efficiency. In addition, the streamlined shape helps the bullet retain velocity as range increases. Therefore, it supports a flatter trajectory and can help reduce the effect of wind.

For reloaders, the secant-ogive design can also provide useful flexibility when tuning seating depth. In particular, some rifle and load combinations can be less sensitive to changes in bullet jump. As a result, reloaders may have more freedom when finding a seating depth that produces the best accuracy. However, every rifle and load combination responds differently, so testing remains important.

6.5mm 129gr SST Hunting Performance

The 129 grain weight provides a useful balance of bullet mass and ballistic performance for suitable 6.5mm hunting applications. Furthermore, the .485 G1 BC helps the bullet retain velocity as range increases.

At the same time, the polymer tip drives into the lead core on impact to initiate expansion. In addition, the InterLock ring helps keep the core and jacket together during expansion. As a result, the SST combines efficient flight with controlled terminal performance.

The .264 sectional density also provides a useful balance of bullet weight and diameter. Therefore, this 129 grain projectile is a practical option for hunters looking for an aerodynamic 6.5mm hunting bullet.

However, terminal performance depends on impact velocity, range, shot placement, game and the individual rifle and load. For this reason, reloaders should always use current published load data for the specific cartridge.
