Hornady 3142 SST .310 Caliber 123 Grain Polymer Tip Reloading Bullets, 100 Count

Hornady 3142 SST, or Super Shock Tip, reloading bullets are designed for rapid, reliable expansion and strong impact performance at higher velocities. With a .310-inch diameter and 123-grain weight, these bullets are suited for .30-caliber and 7.62mm-class rifle cartridges when matched with the appropriate loading data and firearm specifications. The SST design provides a practical combination of accuracy, flat trajectory, and downrange energy for hunting applications.
The streamlined polymer tip initiates expansion while improving the bullet’s ballistic coefficient. A secant ogive and boat-tail profile help promote efficient flight and consistent performance at extended ranges. The InterLock ring mechanically secures the lead core and copper jacket, helping the bullet maintain core-jacket integrity during expansion. A cannelure supports reliable bullet seating and crimping when required by the chosen load.
These Hornady reloading bullets are intended for experienced handloaders who follow current, verified load data and safe reloading practices. They are a suitable choice for hunting whitetail deer, antelope, moose, and similar-sized game when used in an appropriate cartridge and with proper shot placement. Each box contains 100 bullets, providing a dependable supply for load development, practice, or hunting preparation. Hornady part number 3142 identifies this SST bullet configuration.
