Hornady 257 117gr SST Bullets

Hornady 257 117gr SST Bullets combine a streamlined secant ogive with a polymer tip and InterLock ring. The 117 grain bullet has a .390 G1 ballistic coefficient and .253 sectional density. As a result, it offers a useful balance of flat trajectory, accuracy and controlled expansion for hunting.

Why Choose Hornady 257 117gr SST?

The Hornady 257 117gr SST uses a secant ogive to reduce drag and improve the bullet’s flight path. In addition, the shape helps retain velocity and supports a flatter trajectory. Hornady also states that the ogive provides a useful bearing surface for stability and ballistic performance.

For reloaders, the secant ogive can also offer useful flexibility when tuning seating depth. In some rifles, this design can be less sensitive to changes in bullet jump. Therefore, reloaders may find the seating-depth tuning process less critical, although each rifle and load still needs testing.

Hornady 257 117gr SST Hunting Performance

The 117gr SST suits hunters who want a balance of trajectory and terminal performance. Furthermore, the secant ogive and .390 G1 BC help the bullet retain useful speed as range increases.

At the same time, the polymer tip drives into the lead core on impact and starts expansion. The InterLock ring then helps keep the core and jacket together during expansion. As a result, the bullet combines efficient flight with controlled terminal performance.

For this reason, the 117 grain weight makes the bullet a useful option for suitable .257″ calibre hunting cartridges. However, actual results depend on impact velocity, range, shot placement, rifle and load.

Therefore, reloaders should use current published load data and test seating depth and accuracy in their own rifle.
