357 MAGNUM AND 357 MAGNUM BULK AMMO

About 357 Magnum Ammo

Introduced in 1935, 357 Magnum ammo (also known as .357 Magnum or 357 ammo) was the result of a groundbreaking collaboration between Smith & Wesson and legendary firearms innovators Elmer Keith and Phillip Sharpe.

By modifying and lengthening the .38 Special case to hold more powder and handle higher pressures, they created the world’s first commercially successful magnum handgun cartridge, setting the stage for decades of revolver innovation.

Originally developed to deliver superior velocity, penetration, and stopping power compared to existing handgun rounds, 357 Magnum ammunition quickly gained favor with law enforcement agencies across the United States, especially for its ability to penetrate early ballistic vests and automobile bodies—something no other handgun cartridge of its time could reliably achieve.

Beyond its law enforcement success, 357 Magnum ammo quickly won over civilian shooters, hunters, and competitive marksmen.

Its remarkable versatility made it a go-to choice for self-defense, hunting small to medium game (like deer and hogs), target shooting, and cowboy action competitions. When paired with carbines or lever-action rifles, the cartridge delivers even greater performance, offering shooters a flat trajectory, deep penetration, and legendary knockdown power.

One of the cartridge’s greatest advantages is its ability to fire lighter .38 Special loads, making it an exceptionally flexible option for both beginners and experienced shooters. Over the decades, 357 Magnum has influenced the design of many subsequent magnum cartridges, solidifying its role as a true pioneer in handgun ammunition.

Today, 357 Magnum ammunition is offered by nearly all major manufacturers, available in everything from soft-shooting range loads to hard-hitting hunting and self-defense rounds. Its unmatched balance of power, accuracy, and versatility continues to make it one of the most popular and enduring handgun cartridges in the world.

Whether you’re a law enforcement professional, a hunter in search of your next trophy, or a revolver enthusiast hitting the range, 357 Magnum ammo remains a proven and respected choice in the firearms community.

357 Magnum Ammunition Features

357 Magnum ammo is famous for its high velocity and impressive muzzle energy, often reaching speeds between 1,200 and 1,600 feet per second depending on the load.

This power translates to outstanding stopping power and deep penetration, making it ideal for self-defense, hunting, and tactical use.

Versatile Applications
One of the biggest advantages of 357 Magnum ammunition is its versatility. It’s suitable for:

• Self-defense
• Law enforcement and duty use
• Small- to medium-game hunting
• Target and competitive shooting
• It can also safely fire .38 Special ammunition in most revolvers chambered for 357 Magnum, adding even more flexibility.
• Flat Trajectory and Excellent Accuracy

Thanks to its high speed and balanced ballistics, 357 Magnum offers a flat trajectory that makes it easier to shoot accurately at both short and moderate ranges. Whether used in a revolver or a lever-action rifle, it’s known for delivering precise, repeatable shots.

Wide Range of Bullet Types
357 Magnum ammo is available in multiple bullet types to match specific needs:

• Full Metal Jacket (FMJ) for target shooting and training
• Jacketed Hollow Point (JHP) for self-defense
• Soft Point (SP) and Bonded Bullets for hunting
• Lead Semi-Wadcutter (LSWC) for competition and practice

This wide selection ensures you can find the perfect load for any application.

Manageable Recoil
Despite its power, 357 Magnum ammo has moderate recoil, making it accessible to both seasoned shooters and confident beginners. When shooting lighter .38 Special loads in a 357 Magnum revolver, recoil is even milder, making it a great option for training or introducing new shooters to revolvers.

Proven Reliability
With nearly a century of proven field performance, 357 Magnum ammunition remains one of the most reliable and trusted handgun cartridges worldwide. Whether carried for protection, used for competition, or packed for a backcountry hunt, shooters count on its consistent results.

Common 357 Magnum Ammo Types

Here’s a breakdown of the most popular 357 Magnum ammunition types available today:

Full Metal Jacket (FMJ)
FMJ ammo features a soft lead core encased in a hard metal jacket, making it an excellent choice for target shooting, range practice, and plinking. It’s affordable, reliable, and designed to minimize barrel fouling, but it’s not typically recommended for self-defense due to its limited expansion.

Jacketed Hollow Point (JHP)
JHP rounds are the go-to option for self-defense and law enforcement. The hollow cavity at the tip promotes rapid expansion on impact, creating larger wound channels and minimizing over-penetration. JHP 357 Magnum ammo offers a balance of stopping power and safety, making it a top pick for concealed carry and home defense.

Soft Point (SP)
Soft Point ammo features a partially exposed lead tip that expands more slowly than JHP bullets. This design delivers deep penetration with controlled expansion, making SP rounds an excellent choice for hunting small to medium game such as deer or hogs.

Lead Semi-Wadcutter (LSWC)
LSWC bullets have a flat nose and sharp shoulder, designed to cut clean holes in paper targets. These are highly favored by competitive shooters and target enthusiasts for their accuracy and clean scoring on paper and steel targets.

Bonded Bullets
Bonded bullets combine a lead core and a copper jacket that are chemically or mechanically bonded together, ensuring maximum weight retention and deep penetration. They’re especially popular in law enforcement, self-defense, and hunting applications where barrier penetration is critical.

Specialty Loads
357 Magnum ammo is also available in specialty configurations, including:

• Reduced recoil loads for beginners or sensitive shooters
• Heavy grain hunting loads for larger game
• Frangible rounds for training on steel targets or use in indoor ranges
• Choosing the Right 357 Magnum Ammo
• Range practice: Full Metal Jacket (FMJ)
• Self-defense: Jacketed Hollow Point (JHP), Bonded JHP
• Hunting: Soft Point (SP), Heavy-grain Bonded bullets
• Competition: Lead Semi-Wadcutter (LSWC)
