Hornady 7mm 139gr SST Bullets

Hornady 7mm 139gr SST Bullets combine a streamlined secant ogive with a polymer tip and InterLock construction. The 139 grain bullet has a .486 G1 ballistic coefficient and .246 sectional density. As a result, it offers a strong balance of trajectory, accuracy and controlled expansion for suitable 7mm hunting applications.

Why Choose Hornady 7mm 139gr SST?

The Hornady 7mm 139gr SST uses a secant ogive to create a streamlined profile. In addition, this shape helps reduce drag and retain velocity downrange. Therefore, the bullet can produce a flatter trajectory and less wind drift than a less aerodynamic design.

For reloaders, the secant-ogive profile can also provide useful flexibility when tuning seating depth. In some rifles, this design can be less sensitive to changes in bullet jump. As a result, seating-depth tuning may be less critical during load development, although every rifle and load combination still needs testing.

Hornady 7mm 139gr SST Hunting Performance

The 139gr SST suits hunters who want a balance of flat trajectory and terminal performance. Furthermore, the .486 G1 BC helps the bullet retain velocity as range increases.

At the same time, the polymer tip initiates expansion on impact. 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 139 grain weight also gives the bullet a .246 sectional density. Therefore, it provides useful weight and penetration potential for suitable 7mm hunting applications.

However, actual terminal performance depends on impact velocity, range, shot placement, game and the individual rifle and load. For this reason, reloaders should use current published load data and test accuracy and seating depth in their own rifle.
