The Hornady SST 270 140 grain rifle bullets are a proven choice for reloaders building loads for whitetail, mule deer, and mid-sized North American game. Built around Hornady's InterLock technology and polymer-tipped design, these bullets deliver consistent expansion and reliable performance across a wide velocity range. If you're handloading ammunition in .270 Winchester or similar cartridges, a box of 100 SST bullets gives you the component count to develop and shoot through a serious practice and hunting season.

The InterLock ring is the heart of the SST's design—it mechanically locks the copper jacket to the lead core during expansion, preventing separation and ensuring the bullet retains mass for deep penetration and a substantial wound channel. This matters when you're depending on your load to perform on game at distance. The polymer tip serves double duty: it boosts the ballistic coefficient for a flatter trajectory and more retained energy downrange, while also initiating controlled expansion upon impact. The combination of the secant ogive boattail profile and the tip design produces the velocity and efficiency hunters expect from a modern hunting bullet.

A cannelure groove runs around the bearing surface, giving you a precise crimping point during the reloading process and working in concert with the InterLock ring to manage expansion. Whether you're loading for a hunting trip in October or practicing at the range to confirm zero before the season, these 140-grain bullets are a straightforward, field-proven component for .270 caliber rifles.
