Remington 40 S&W 155 Grain Ammo

Remington 40 S&W 155 Grain Ammo Overview

The Remington 40 S&W 155 grain cartridge is a popular loading for the .40 S&W semi-automatic pistol caliber. Featuring a 155 grain full metal jacket (FMJ) bullet, this ammunition delivers a balance of power, accuracy, and reliability.

The 155 grain projectile is constructed with a copper jacket over a lead core, providing good penetration and consistent downrange performance. This bullet design makes the Remington 40 S&W 155 grain load suitable for a variety of applications, including target shooting, self-defense, and law enforcement use.

When fired from a typical 4-inch .40 S&W barrel, this Remington ammunition achieves muzzle velocities around 1,150 feet per second. This velocity, combined with the 155 grain bullet weight, results in over 450 foot-pounds of muzzle energy – providing ample stopping power for personal protection and law enforcement applications.

In terms of terminal ballistics, the 155 grain FMJ bullet is designed for full penetration rather than rapid expansion. This makes it less suitable for maximum wound effectiveness in self-defense situations, but effective for target engagement and some law enforcement use.

The Remington 40 S&W 155 grain cartridge is widely available and competitively priced, making it a popular choice for recreational shooting, training, and duty use with .40 caliber semi-automatic pistols. Its consistent performance and cost-effectiveness have led to its broad adoption by both civilian and law enforcement shooters.

Remington 40 S&W 155 Grain Ammo Properties

Cartridge Specifications:
The 40 S&W 155 grain cartridge has an overall length of 1.15 inches and a case length of 0.850 inches. The bullet diameter is 0.400 inches, matching the bore diameter of the .40 S&W caliber.

As mentioned, the projectile utilizes a full metal jacket (FMJ) design, with a copper alloy jacket surrounding a lead core. This construction provides good penetration and consistent performance, making it suitable for target shooting, training, and some law enforcement applications.

Ballistic Performance:
When fired from a typical 4-inch barrel, the Remington 40 S&W 155 grain load achieves muzzle velocities around 1,150 feet per second. This generates over 450 foot-pounds of muzzle energy.

The 155 grain bullet’s ballistic coefficient of approximately 0.170 allows it to retain velocity and kinetic energy reasonably well at longer ranges. This gives the .40 S&W load a flatter trajectory and better downrange performance compared to lighter bullet weights.

In terms of terminal ballistics, the FMJ bullet is designed for penetration rather than rapid expansion. While this makes it less ideal for maximum wound effectiveness in self-defense situations, the 155 grain projectile is still capable of reliably incapacitating threats when placed accurately.

Usage and Applications:
The Remington 40 S&W 155 grain ammunition is a popular and widely available loading, making it a common choice for general-purpose pistol use. It is frequently employed for target shooting, training, and some law enforcement applications.

While not an optimal self-defense round due to its penetration-focused bullet design, the 155 grain FMJ is sometimes used for home defense or personal protection when other hollow point options are unavailable. Its balance of power and affordability make it a viable option in these scenarios.

The reliability and consistent performance of this Remington load have also contributed to its widespread use for law enforcement duty and qualification purposes. Its capabilities are well-suited for the practical demands of law enforcement applications.

Overall, the Remington 40 S&W 155 grain cartridge represents a reliable and affordable option for those seeking a balanced and versatile .40 caliber loading. Its combination of power, accuracy, and affordability have made it a go-to choice for many shooters and law enforcement professionals.
