Federal American Eagle .357 SIG 125 Grain Full Metal Jacket (FMJ) Ammo
High-velocity target and range training ammunition engineered to match the recoil impulse and trajectory of personal defense loads. Federal American Eagle .357 SIG 125gr FMJ combines reloadable brass cases, non-corrosive Boxer primers, and smooth-feeding full metal jacket bullets in a 50-round box.
Product Overview
Federal American Eagle .357 SIG 125 grain FMJ ammunition (Part #AE357S2) delivers high-volume shooting reliability and realistic practice for duty and personal carry sidearms. Designed to replicate the point-of-impact and terminal velocity of standard 125gr tactical hollow points, this target load enables shooters to build skill without burning through high-cost defense ammo.
Featuring a 125-grain Full Metal Jacket projectile, it provides smooth feeding through bottlenecked .357 SIG chambers and prevents lead fouling in the barrel. Operating at a blistering muzzle velocity of 1,350 fps with 506 ft-lbs of energy, it offers the signature flat trajectory and snappy performance expected from the caliber. Loaded in clean-burning reloadable brass cases with dependable non-corrosive Boxer primers, each 50-round box provides clean, consistent performance.

Compatibility & Usage Notes
This ammunition is designed for handguns chambered in .357 SIG in sound operating condition. It functions smoothly in full-size duty pistols and compact carry firearms, such as Glock 31/32/33, SIG Sauer P229, and M&P357 platforms. Always check caliber markings on your barrel before loading. Store ammunition in a cool, dry place away from children and unauthorized persons.
Frequently Asked Questions
Can I use Federal American Eagle .357 SIG for self-defense?
While Full Metal Jacket (FMJ) ammunition will function reliably, non-expanding FMJ bullets present an over-penetration risk and are recommended strictly for range training and target practice. Hollow point loads like Speer Gold Dot or Federal HST are preferred for defensive use.
Are American Eagle .357 SIG casings reloadable?
Yes. The high-quality brass casings utilize standard non-corrosive Boxer primers and can be reloaded.
Is .357 SIG ammo compatible with .357 Magnum revolvers?
No. The .357 SIG is a rimless, bottlenecked semi-automatic pistol cartridge and is completely incompatible with .357 Magnum revolvers.
