Hornady SST 140 Grain .277 Caliber Super Shock Tip Rifle Bullets for .270 Winchester – Unmatched Performance for Medium to Large Game

For the dedicated hunter and precision reloader, selecting the right projectile is paramount to achieving consistent, ethical harvests. The Hornady SST 140 grain .277 caliber Super Shock Tip bullets (SKU: 27352), designed specifically for cartridges like the popular .270 Winchester, represent a pinnacle of modern hunting bullet technology. These bullets are engineered to deliver a devastating combination of flat trajectory, exceptional accuracy, and rapid, reliable terminal performance across a wide range of North American and similar-sized African plains game.

When hunters ask, "What is the best bullet for deer in .270 Winchester?" or "Which bullet offers reliable expansion for elk and moose?", the Hornady SST frequently emerges as a top recommendation. It's built for those who demand precision and powerful knock-down performance, making it an ideal choice for hunters pursuing whitetail deer, mule deer, pronghorn antelope, elk, and even larger species such as moose. The inherent design of the Super Shock Tip ensures that energy is transferred efficiently upon impact, leading to quick, humane takedowns.

Key Features and Engineering Excellence of the Hornady SST

The Hornady SST bullet is a testament to meticulous design and advanced manufacturing. Each feature contributes directly to its superior performance in the field.

• Polymer Tip for Enhanced Ballistics and Initiation of Expansion: At the core of the SST's innovation is its sleek, red polymer tip. This tip serves a dual purpose. Firstly, it significantly increases the ballistic coefficient (BC) of the bullet, allowing it to cut through the air with minimal drag. A higher BC translates to flatter trajectories, greater retained velocity, and more energy delivered downrange, making long-range shots more manageable and consistent. Secondly, the polymer tip acts as a wedge upon impact, initiating rapid and controlled expansion even at varying velocities, ensuring consistent terminal performance whether the shot is close or at extended ranges.
• Secant Ogive Boat-Tail Profile for Aerodynamic Efficiency: The bullet's secant ogive shape, combined with a boat-tail base, is crucial for its aerodynamic stability and efficiency. A secant ogive nose cone is a mathematically optimized shape that reduces drag more effectively than traditional tangent ogives. This design minimizes air resistance, preserving velocity and energy for maximum effectiveness at the target. The boat-tail design further reduces base drag, contributing to a flatter trajectory and improved accuracy, especially over longer distances. Hunters seeking to minimize bullet drop and wind drift will find this feature invaluable.
• InterLock Ring for Core-Jacket Integrity: One of Hornady's signature technologies, the InterLock ring, is an integral part of the SST bullet's design. This raised ring is molded into the core of the bullet, mechanically locking the lead alloy core to the copper jacket. This patented feature ensures that the core and jacket remain unified during the violent process of expansion. Unlike some conventional bullets where the core can separate from the jacket, leading to inconsistent penetration or energy transfer, the InterLock ring guarantees deep penetration and high weight retention, which are critical for effective energy transfer and clean kills on larger game. This structural integrity ensures the bullet performs as designed, even after encountering tough hide or bone.
• Super Shock Tip (SST) Technology for Devastating Terminal Performance: The "Super Shock Tip" moniker is not just a name; it describes the bullet's core function. It's engineered for tremendous shock on impact, expanding quickly and reliably to create a wide wound channel. This rapid energy transfer is vital for dropping game quickly and ethically. Whether it's a whitetail deer or a large elk, the SST delivers the necessary shock and tissue damage to ensure a swift, humane harvest.

Performance Metrics and What They Mean for the Hunter

Understanding the ballistic properties of a bullet helps hunters and reloaders make informed decisions. The Hornady SST 140 grain .277 caliber bullet boasts impressive specifications:

• Bullet Weight: 140 grains. This weight offers an excellent balance of velocity, energy, and stability for the .270 Winchester, providing a versatile option for various game sizes.
• Bullet Diameter: .277 inches. This is the standard diameter for .270 Winchester projectiles, ensuring compatibility with factory ammunition specifications and reloading dies.
• Ballistic Coefficient (BC): .495 (G1). This high BC indicates superior aerodynamic efficiency, meaning the bullet retains velocity and energy exceptionally well downrange, resisting wind drift more effectively. This is a significant advantage for ethical long-range hunting.
• Sectional Density (SD): .261. Sectional density is a measure of a bullet's penetrating capability based on its weight and diameter. A high sectional density like .261 suggests excellent penetration potential, especially when combined with controlled expansion, making it suitable for reaching vital organs in larger, tougher game.
• Core Material: Lead. A traditional and effective core material, optimized for controlled expansion within the jacket.
• Jacket Material: Copper. The standard for rifle bullet jackets, providing strength, formability, and reliable performance.
• Bullet Tip Material: Polymer. As discussed, this enhances both ballistic efficiency and expansion initiation.

Ideal Applications: Who Benefits Most from the Hornady SST?

The Hornady SST 140 grain .277 Super Shock Tip is a versatile hunting bullet that excels in numerous scenarios, making it a favorite among a diverse group of hunters and shooters:

• Whitetail and Mule Deer Hunters: For many, the .270 Winchester is a quintessential deer cartridge, and the SST is arguably one of its finest projectiles. Its flat trajectory and rapid expansion are ideal for quick, humane kills on medium-sized game, whether in open fields or dense timber.
• Elk and Moose Hunters: While often considered a deer bullet, the 140-grain SST, particularly when driven by a potent .270 Winchester load, has proven effective on larger game like elk and even moose. The combination of its deep penetration (thanks to the InterLock ring and good sectional density) and significant energy transfer makes it a viable option for these tougher animals, provided shot placement is precise.
• Pronghorn and Antelope Hunters: The SST's flat-shooting nature and high BC make it perfect for the often-long-range shots encountered when hunting open-country antelope species. Minimal bullet drop and wind deflection are critical for success in these environments.
• African Plains Game Hunters: For similar-sized African plains game, such as Kudu, Gemsbok, or Wildebeest, the SST offers a reliable balance of penetration and rapid energy release, ensuring effective performance on these resilient animals.
• Reloaders Seeking Precision and Performance: Handloaders appreciate the consistent quality and uniformity of Hornady bullets. The SST allows reloaders to fine-tune their loads for optimal accuracy from their specific rifle, maximizing the performance potential of their .270 Winchester. This control over components and powder charges often leads to sub-MOA (Minute of Angle) groups, building confidence for critical shots in the field.
• Hunters Prioritizing Ethical Harvests: The fundamental design goal of the SST is rapid, humane incapacitation. Its ability to deliver a powerful shock and create a devastating wound channel minimizes animal suffering, aligning with the principles of ethical hunting.
