Is consistent accuracy from your 7mm STW rifle a non-negotiable requirement for your next hunt? The Nosler Trophy Grade 140 gr Partition load is meticulously crafted to answer these very questions, providing the discerning hunter with the confidence needed to make that critical shot.

This premium factory ammunition is specifically designed for the powerful 7mm STW (Shooting Times Western) cartridge, a true magnum known for its flat trajectory and impressive energy. By pairing this high-performance cartridge with the legendary Nosler Partition bullet, Nosler has created a synergy that defines reliable big-game performance.

Why Choose Nosler Trophy Grade 7mm STW 140 gr Partition Ammunition?

Hunters often ask, "What's the best ammunition for large game animals?" or "How can I ensure clean, ethical harvests?" The answer frequently points to ammunition that combines superior bullet design with meticulous manufacturing standards. Nosler's Trophy Grade line represents the pinnacle of their factory loaded ammunition, leveraging decades of bullet-making expertise.

• Unrivaled Terminal Performance: The core problem faced by hunters is ensuring a quick, humane kill. The Nosler Partition bullet, the heart of this ammunition, is renowned for its unique dual-core design, which guarantees controlled expansion in the forward section while retaining the rear core for deep penetration, even through heavy bone and muscle.
• Exceptional Accuracy: Each Nosler Trophy Grade round is manufactured to precise standards, ensuring shot-to-shot consistency. This means tighter groups at the range and greater confidence in the field.
• Optimized for 7mm STW: This specific loading is tailored to extract the maximum ballistic potential from the 7mm STW cartridge, delivering impressive velocities and energy figures critical for long-range engagements and swift takedowns.
• Reliability in All Conditions: From the freezing temperatures of a mountain hunt to the humid conditions of a lower elevation chase, Nosler Trophy Grade ammunition is built to perform reliably, minimizing the risk of misfires or inconsistencies when it matters most.

The Legendary Nosler Partition Bullet: A Deeper Dive into Its Design

At the heart of the Nosler Trophy Grade 7mm STW 140 gr offering is the iconic Nosler Partition bullet. Introduced over 70 years ago, the Partition revolutionized hunting bullet design and remains a benchmark for terminal performance on tough game. What makes it so effective?

The Partition bullet features a unique, internal lead alloy partition located at the bullet's midpoint. This design element separates the bullet into two distinct sections:

1. Front Core: Designed for rapid, controlled expansion upon impact. This front section mushrooms efficiently, creating a large wound channel that transfers maximum energy to the target.
2. Rear Core: Protected by the solid partition, this section maintains its integrity, ensuring significant weight retention and continued, deep penetration through vital organs and heavy bone.

This innovative dual-core construction ensures that the bullet performs reliably across a wide range of impact velocities. Whether striking game at close range with high velocity or at extended distances where velocity has dropped, the Partition consistently delivers both expansive energy transfer and the necessary penetration for a clean pass-through or recovery. This predictable performance is a cornerstone of ethical hunting, minimizing tracking and ensuring a humane outcome.

Ballistics and Real-World Performance: What to Expect in the Field

The 7mm STW is a potent cartridge, and when paired with the 140-grain Nosler Partition, it delivers a formidable ballistic package. For hunters considering "how far can I shoot accurately with a 7mm STW?" or "what kind of energy does this round deliver?", understanding its ballistics is crucial.

• Muzzle Velocity (MV): Typically, the 140-grain Nosler Partition in 7mm STW achieves muzzle velocities in the range of 3300-3350 feet per second (fps). This exceptional speed contributes to a remarkably flat trajectory.
• Muzzle Energy (ME): With such high velocity, the muzzle energy often exceeds 3400 foot-pounds (ft-lbs), providing immense knockdown power for even the largest North American game.
• Ballistic Coefficient (BC): The 140-grain Partition bullet typically has a G1 Ballistic Coefficient (BC) of approximately 0.450. While not the highest BC in its class, its consistent shape and Nosler's manufacturing precision ensure predictable flight characteristics.
• Sectional Density (SD): At 0.248, the 140-grain Partition boasts a respectable sectional density, contributing to its excellent penetration capabilities, especially given its robust construction.

These ballistic figures translate directly into superior field performance. The flat trajectory of the 7mm STW means less bullet drop over distance, simplifying holdover calculations for long-range shots. The high energy and the Partition's reliable expansion and penetration ensure that when the bullet finds its mark, it delivers a decisive blow, minimizing the animal's suffering and increasing the likelihood of a quick recovery. This is precisely what hunters mean when they ask for "reliable one-shot performance."

Ideal Applications and Hunting Scenarios

Who benefits most from the Nosler Trophy Grade 7mm STW 140 gr Partition? This ammunition is an outstanding choice for a variety of hunting applications, particularly where large, tough game and potentially longer shot opportunities are anticipated.

• Elk Hunting: The 7mm STW, combined with the Partition bullet, is a stellar elk cartridge. Its ability to penetrate heavy muscle and bone and deliver deep energy transfer is exactly what's needed for the often-thick-skinned and robust anatomy of an elk.
• Moose Hunting: Similar to elk, moose are massive animals requiring significant power and penetration. The 140 gr Partition excels in this role, providing the necessary terminal performance for a humane harvest.
• Large Bear Species (Black Bear, Brown Bear): While shot placement is always critical, the Partition's controlled expansion and penetration make it suitable for bear hunting, especially in situations where a bear might be quartering away or presenting a challenging angle.
• Long-Range Deer Hunting: For hunters pursuing larger deer species like mule deer or even robust whitetails in open terrain, the flat-shooting characteristics of the 7mm STW with the 140 gr Partition make it an excellent choice for extending effective range while maintaining ethical performance.
• Mountain Hunting: In mountainous terrain, shot distances can be unpredictable. The 7mm STW's flat trajectory helps compensate for challenging uphill/downhill angles and varying ranges, while the Partition's consistent performance across velocities ensures effectiveness.

This ammunition empowers hunters to confidently tackle their most ambitious hunts, knowing their equipment is up to the task.

Maintaining Ammunition Quality and Storage

To ensure your Nosler Trophy Grade ammunition performs as intended, proper storage is vital. Like all high-quality ammunition, it should be kept in a cool, dry place, away from direct sunlight and extreme temperature fluctuations. Avoiding high humidity helps prevent corrosion and preserves primer and powder integrity. Storing ammunition in its original packaging or in dedicated ammunition cans is recommended to protect it from environmental elements and physical damage. This simple practice helps ensure that when you reach for your rounds, they are in optimal condition for peak performance.

Beyond the Barrel: The Nosler Commitment to Quality

Nosler's reputation in the shooting sports community is built on a foundation of innovation, precision, and a relentless commitment to quality. The Trophy Grade line embodies this ethos. Every component, from the brass casing to the propellant, the primer, and of course, the legendary Partition bullet, is subjected to rigorous quality control. This attention to detail means that hunters receive ammunition that performs consistently, shot after shot, box after box. This level of dedication translates directly into the reliability and confidence that serious hunters demand, knowing their ammunition won't let them down when the opportunity of a lifetime presents itself. This unwavering commitment is why Nosler Trophy Grade ammunition is often recommended by seasoned professionals and experienced hunters alike, readily available from trusted suppliers like DEGuns.

In summary, the Nosler Trophy Grade 7mm STW 140 gr Partition ammunition is more than just a box of cartridges; it's a meticulously engineered solution for the demanding big game hunter. It addresses the critical need for reliability, precision, and ethical terminal performance, allowing hunters to focus on their craft with utmost confidence.
