Enter the 28 Nosler, a modern powerhouse engineered for exceptional performance. This article will dive deep into a comprehensive comparison, meticulously examining the 7mm Rem Mag vs 28 Nosler, and revealing which cartridge reigns supreme for your specific needs.
The world of rifles and ammunition is a competitive one, constantly striving for improvements in performance, range, and efficiency. Before dissecting the specifics, a historical understanding of each contender is paramount.
The 7mm Remington Magnum, often affectionately called the “7mm Rem Mag,” has a rich legacy. Introduced by Remington in 1962, it quickly ascended to popularity, becoming a mainstay for hunters seeking a flat-shooting, versatile cartridge. Its ability to effectively take down various game animals at respectable distances, combined with readily available factory ammunition and relatively affordable rifles, solidified its position in the hunting community. The 7mm Rem Mag offered a substantial upgrade over existing 7mm options, providing increased velocity and flatter trajectories. It became a darling of many hunters due to its versatility for multiple game species.
Fast forward to the modern era, and the shooting world demanded an upgrade, aiming for better ballistic performance. Enter the 28 Nosler. Unveiled in 2014 by Nosler, this cartridge aimed to push the boundaries of 7mm performance. Built on a longer case and utilizing a modern case design, the 28 Nosler was engineered to achieve higher velocities, flatter trajectories, and deliver more energy at extended ranges. The design intent was simple: to create a cartridge optimized for long-range hunting and target shooting, offering superior downrange performance. Its introduction signaled a new era of performance and power in the 7mm world.
Unveiling the Internal Architecture
To fully grasp the nuances of the 7mm Rem Mag vs 28 Nosler debate, a close inspection of their physical attributes is vital. These specifications profoundly influence the performance of each cartridge.
Let’s start with dimensions. The 7mm Rem Mag, based on the .375 H&H Magnum case, boasts a case capacity that allows for a good amount of propellant. This, in turn, contributes to its notable ballistic performance. In contrast, the 28 Nosler, utilizing a longer case based on the .404 Jeffery case, possesses a significantly larger case capacity. The increased powder volume is one of the primary factors driving its higher velocities. This case capacity difference is the cornerstone upon which the rest of the performance comparisons are built.
Now, considering bullet selection, both cartridges share the same 7mm bullet diameter, enabling a wide range of projectile weights and designs. The 7mm Rem Mag traditionally finds its sweet spot with bullets in the 140 to 175-grain range. These bullets offer excellent ballistic coefficients and maintain sufficient energy for a variety of game. The 28 Nosler, thanks to its increased powder capacity, can efficiently launch heavier, higher ballistic coefficient bullets, commonly utilizing bullets in the 160-to-195-grain range. These heavier bullets translate to superior long-range performance, with better resistance to wind drift and enhanced energy delivery at extended distances. The ability to handle these heavier projectiles is a core strength of the 28 Nosler.
Sectional Density and Ballistic Coefficients are crucial for judging performance. Ballistic coefficient (BC) measures how efficiently a bullet flies through the air, with higher numbers indicating greater aerodynamic efficiency. Sectional density (SD) is a measure of a bullet’s weight relative to its diameter. Higher SD generally means greater penetration ability. In this context, the 7mm Rem Mag typically utilizes bullets with BCs in the moderate range. The 28 Nosler excels here, as it can launch bullets with much higher BCs. These advanced bullet designs provide a flatter trajectory, which leads to less bullet drop over long distances. This is one area where the 28 Nosler often clearly outperforms the 7mm Rem Mag.
Comparing Ballistic Performance: A Detailed Analysis
The real test of any cartridge is its performance in the field. Let’s compare key performance metrics for the 7mm Rem Mag vs 28 Nosler.
Velocity and trajectory are the primary determinants of how a bullet behaves over distance. The 28 Nosler has a clear advantage here. Because of its larger case capacity, it can generate significantly higher muzzle velocities, often exceeding 3,000 feet per second with many bullet choices. The 7mm Rem Mag also delivers good velocities, but typically it will not reach those speeds. That higher velocity results in a flatter trajectory and faster time-of-flight. This translates to less bullet drop at longer distances, simplifying aiming and increasing the probability of hitting your target.
Next is energy on impact. While muzzle velocity is critical, what matters most is the energy a bullet retains at the intended target. The 28 Nosler, again, holds an advantage. Its higher velocity, coupled with its capacity for heavier bullets, leads to superior energy delivery at longer ranges. This can be critical for ensuring sufficient penetration and terminal performance when hunting large game animals at extended distances. The 7mm Rem Mag still delivers considerable energy, but often it will not hold as much at longer ranges when compared to the 28 Nosler.
Wind drift can drastically alter the precision of a shot. This is where the ballistic coefficient shines. The 28 Nosler’s ability to fire bullets with extremely high ballistic coefficients means that it resists the influence of wind more effectively. Less wind drift translates to greater accuracy at longer ranges, crucial for ethical hunting and competitive shooting. While the 7mm Rem Mag does well, the 28 Nosler will generally exhibit less wind drift at extended distances.
Recoil is the final aspect to consider. The greater powder charge of the 28 Nosler typically translates into a higher recoil impulse than the 7mm Rem Mag. This increased recoil can impact shooting comfort, and it can potentially affect the shooter’s ability to maintain accuracy. The 7mm Rem Mag is generally acknowledged as easier to handle, enabling faster follow-up shots. Though proper rifle setup and the use of muzzle brakes can help mitigate recoil with the 28 Nosler, shooters must be aware of its more powerful kick.
Hunting Realm: Where the Rubber Meets the Road
The best way to compare the two is by discussing their effectiveness in the field.
The 7mm Rem Mag is a versatile hunting cartridge. It’s well-suited for various game animals, including deer, elk, and many African plains game species. Its range of bullet weights and good ballistic performance make it a capable choice for diverse hunting situations.
The 28 Nosler, designed for maximum performance, particularly excels in long-range hunting scenarios. It’s at its best when hunting larger game animals at extended distances. Think elk, mule deer, and other species where a flat trajectory and retained energy at long ranges are critical for ethical, successful hunts. The 28 Nosler shines in situations where the distance to the target is substantial. Its superior ballistic coefficient ensures it is less affected by wind.
Considering the strengths of each, the 7mm Rem Mag will be the better choice for many hunters and many hunting situations. However, the 28 Nosler is the superior choice when long-range performance and maximum energy at distance are the key.
The Practical Side of the Equation
