- 270 Cal (.277 diameter), 140 grain — heavier option for improved penetration on deer
- Component projectiles for hand-loading; not loaded ammunition
The Hornady SST (Super Shock Tip) in 270 calibre at 140 grains is a hunting bullet built for flat-shooting centrefire rifles where reliable expansion and deep penetration are the priority. At .277-inch diameter and 140 grains, it sits in the heavier end of the 270 Winchester weight range, offering greater sectional density for penetration on larger deer and woodland game. The hard polymer tip is driven into the lead core on impact, acting as a wedge to initiate fast, controlled expansion and create a wide, consistent wound channel. The boattail secant ogive profile lowers drag and stabilises the bullet across the trajectory. A mid-body cannelure keeps core and jacket together under load and provides a reliable crimping point during the reloading process. Hornady's InterLock ring — a mechanical collar that bonds the core and jacket — maintains bullet integrity through expansion, maximising weight retention and making complete pass-throughs more likely. These are component projectiles for hand-loading; they are not loaded ammunition.
