The Magtech Sport Shooting .357 Magnum 125gr FMJ-Flat is a popular choice for shooters who want the power and "snap" of a .357 Magnum without the high cost of premium hollow-point defensive loads.
Here is a breakdown of what you can expect from this specific 50-round box:
Technical Specifications
| Feature | Specification |
| Caliber | .357 Magnum |
| Bullet Weight | 125 Grain |
| Bullet Type | Full Metal Jacket Flat (FMJ-Flat) |
| Muzzle Velocity | ~1,453 fps |
| Muzzle Energy | ~586 ft-lbs |
| Casing | Brass (Reloadable) |
| Primer | Boxer |
Key Performance Characteristics
- Flat Nose Profile: The "Flat" in FMJ-Flat serves two purposes. First, it makes the rounds safe for use in lever-action rifles with tubular magazines (preventing the tip of one round from hitting the primer of the next). Second, it creates cleaner, more visible holes in paper targets compared to a standard round nose.
- Recoil & Velocity: At 125 grains, this is a "light and fast" load. You will experience a sharper, snappier recoil and a more significant muzzle flash compared to heavier 158-grain loads.
- Target Performance: This is strictly "Sport Shooting" ammunition. Because it is a Full Metal Jacket, it does not expand upon impact. It is designed for punching paper, ringing steel, and general plinking—not for self-defense or hunting.
Why Choose This Load?
- Cost-Effective Training: It allows you to train with the actual caliber you might carry, helping you manage the recoil and report of a Magnum at a lower price point.
- Clean Burning: Magtech is generally well-regarded for using consistent powders that don't leave excessive residue in your cylinder or barrel.
- Dual-Purpose: Excellent for both revolvers (like the S&W 686 or Ruger GP100) and PCCs (Pistol Caliber Carbines) like the Henry Big Boy or Rossi R92.
