difference. At Trigger Ammo Store, we carry a deep selection of .357 Magnum
ammunition so you can match the load to the job — and get it shipped quickly

What Makes the .357 Magnum So Popular?

Introduced in 1934, the .357 Magnum was built on the .38 Special case but
loaded to significantly higher pressures, delivering a major jump in velocity
and energy. That extra power is why it remains a favorite for self-defense,
home protection, and handgun hunting decades later. One of its biggest
practical advantages: any revolver chambered in .357 Magnum can also safely
fire .38 Special, giving shooters a lower-recoil, lower-cost option for
practice and training.

Types of .357 Magnum Ammo We Carry

• Jacketed Hollow Point (JHP): The go-to choice for
  self-defense and home protection. JHP rounds are engineered to expand on
  impact for reliable terminal performance.
• Full Metal Jacket (FMJ): Affordable, clean-shooting
  rounds ideal for range days, target practice, and high-volume training.
• Soft Point (SP) & Hunting Loads: Heavier,
  controlled-expansion bullets built for hunting deer, hogs, and other
  medium game.
• Frangible & Specialty: Reduced-ricochet options
  for steel targets and close-quarters training.

Common .357 Magnum Bullet Weights

The two most common grain weights are 125 grain and
158 grain. Lighter 125-grain loads tend to be faster with
snappier recoil and are popular for self-defense. Heavier 158-grain rounds
offer deeper penetration and are widely chosen for hunting and outdoor
carry. You’ll also find 110-grain reduced-recoil and 180-grain heavy hunting
options in our catalog.

Frequently Asked Questions

Can I shoot .357 Magnum ammo in a .38 Special revolver?

No. While a .357 Magnum revolver can safely fire .38 Special, the reverse
is not true — never fire .357 Magnum ammo in a firearm rated only for .38
Special.

What’s the best .357 Magnum ammo for self-defense?

Quality jacketed hollow points in the 125- to 158-grain range from
trusted brands are the most common defensive choice. Always confirm
reliability in your specific firearm.
