Hornady SST 270 Cal .277 140gr Hunting Bullets
The Hornady SST (Super Shock Tip) in 270 calibre at 140 grains is a hunting bullet designed for flat-shooting centrefire rifles where reliable expansion and deep penetration are essential. With a .277-inch diameter and 140 grains, it falls in the heavier end of the 270 Winchester weight range, providing greater sectional density for effective performance on larger deer and woodland game.
The hard polymer tip is driven into the lead core upon impact, acting as a wedge to initiate fast, controlled expansion and create a wide, consistent wound channel. The boattail secant ogive profile reduces drag and improves stability across the trajectory.
A mid-body cannelure maintains core and jacket integrity under pressure and offers a reliable crimping point during reloading. Hornady’s InterLock ring enhances bullet retention and performance in high-pressure loads.

FAQ
What makes the Hornady SST bullet effective for hunting larger game?
The hard polymer tip drives into the lead core upon impact, creating fast, controlled expansion and a wide wound channel. Combined with its high sectional density, it ensures reliable penetration on larger deer and woodland game.
How does the boattail secant ogive profile benefit performance?
The boattail secant ogive profile reduces drag and improves aerodynamic stability, resulting in better trajectory and longer effective range.
Is the mid-body cannelure useful for reloading?
Yes, the mid-body cannelure provides a reliable crimping point during the reloading process, helping maintain core and jacket integrity under pressure.
Michael Wilson –
Used these bullets for a recent deer hunt in the woods. The shot expanded reliably and the penetration was deep. The bullet flew straight and hit the target with good accuracy. Very satisfied with performance in the field.
Max Simpson –
Reloading with these bullets has been smooth. The cannelure holds well during crimping and the expansion is consistent. Good for larger game in dense cover.
Sam Skinner –
The bullet performs well in a 270 Winchester. It’s a bit heavier than standard loads, which helps with penetration. Slight delay in expansion on first shot, but stabilized after a few rounds.
Julian Knox –
Excellent for hunting in thick brush. The wound channel is wide and consistent. I’ve used them on several animals and they’ve delivered reliable results.
Lisa Morgan –
Good balance between expansion and penetration. A bit more weight than typical, but works well for larger game. Slight difference in velocity compared to lighter bullets, but manageable.
