The Hornady .308 165 Grain SST® (Super Shock Tip) InterLock® projectile is a component bullet engineered for handloaders targeting medium-to-large game. Built with a polymer tip, secant ogive, and boat-tail profile, this 165-grain bullet achieves a .447 G1 ballistic coefficient to maintain velocity and energy downrange. Upon impact, the polymer tip drives rearward into the lead-alloy core to initiate rapid expansion, while an internal InterLock ring and mid-body cannelure mechanically bind the core to the tapered gilding metal jacket. This construction controls jacket-core separation across an operational velocity window of 2,200 fps to 3,400 fps, delivering large wound channels on game weighing between 23 kg and 680 kg (50 lbs to 1,500 lbs).

• InterLock Internal Ring: Mechanically anchors the lead core to the jacket alongside a mid-body cannelure, preventing core separation and preserving projectile weight during high-velocity impact.
• Polymer Super Shock Tip: Enhances aerodynamic efficiency in flight and acts as a wedge upon target contact to induce immediate, reliable mushrooming.
• Secant Ogive and Boat Tail: Produces a streamlined shape that reduces in-flight drag, stabilizing the projectile for consistent trajectories out to 300 to 400 metres.
• Broad Calibre Compatibility: Sized for standard .30-calibre reloading dies, pairing with brass cases including .308 Winchester, .30-06 Springfield, .300 Winchester Magnum, .300 WSM, and .300 PRC.

Who is the Hornady .308 165 Grain SST Interlock Bullets 100 Pack for?

• Hunters targeting feral pigs, fallow, red, or sambar deer — needs rapid energy transfer on game up to 680 kg, which these 165-grain reloading bullet projectiles deliver via a polymer wedge tip that initiates controlled expansion down to standard hunting velocities.
• Handloaders reloading .308-diameter cartridges — requires a balance of flat trajectory and terminal punch in chamberings such as .308 Winchester and .30-06 Springfield, supplied by a precise .308-inch diameter and a .447 G1 ballistic coefficient packaged in a 100-count box.

Less suitable for: Strictly long-range hunting beyond 400 to 500 metres, where high-BC match-hunting hybrid projectiles with lower-velocity expansion thresholds perform better; or thick-skinned, extremely dangerous game, which requires non-expanding monolithic solid copper projectiles or bonded-core dangerous-game bullets for deep straight-line penetration.
