Hornady SST 270 Cal 150 Grain InterLock Polymer Tip Spitzer Boat Tail Bullets - Box of 100

The Hornady SST 270 caliber 150 grain rifle bullet is a load-it-yourself component engineered for hunters pursuing whitetail, mule deer, antelope, and larger North American game. Built on the proven SST (Super Shock Tip) platform, this interlock polymer-tip spitzer boat-tail round delivers the accuracy, velocity, and terminal performance serious reloaders expect from one of the industry's most trusted bullet lines. Whether you're hand-loading for a precision hunting rifle or building match ammunition for long-range work, the SST 150-grain gives you the ballistic efficiency and consistent expansion to count on in the field.

The polymer tip serves dual purpose: it boosts the ballistic coefficient for a flatter trajectory and reduced wind drift downrange, and upon impact it initiates controlled expansion. The secant ogive boat-tail profile is designed to cut air more efficiently, translating to retained velocity and energy at distance—critical when hunting beyond typical rifle range. The InterLock ring mechanically bonds the jacket to the core, preventing separation during expansion so the bullet holds together and creates a larger, more reliable wound channel rather than fragmenting or losing mass.

A cannelure crimping groove runs around the bullet body, allowing you to seat and crimp with precision and consistency while working in tandem with the InterLock system to manage expansion predictably. For hunters and handloaders who demand repeatability and proven terminal performance, the SST 150-grain in 270 caliber remains a no-nonsense choice across a wide range of hunting scenarios and velocities.

Frequently Asked Questions

What game is the Hornady SST 270 150 grain suitable for?

The SST is proven on whitetail and mule deer across North America. It also performs well on antelope, moose, and comparable-sized game, making it a versatile choice for hunters pursuing medium to large game.

How does the InterLock ring affect bullet performance?

The InterLock ring mechanically locks the jacket to the lead core, preventing separation during expansion. This keeps the bullet together so it retains mass and energy, creating a larger and more consistent wound channel rather than fragmenting.

What does the polymer tip do?

The polymer tip improves the ballistic coefficient for a flatter trajectory and better downrange energy retention. It also initiates controlled expansion when the bullet strikes game, helping ensure reliable and predictable performance on impact.

Are these bullets ready to load, or do I need to prepare them?

These are unloaded bullet components; you will need to assemble them into complete cartridges using your reloading equipment, powder, primer, and brass cases.
