Description

Federal American Eagle 5.7×28mm 40gr TMJ — 500 Rounds

The Federal American Eagle 5.7x28mm AE5728 is the standard-weight range and practice load for the 5.7×28mm platform.

A 40-grain Total Metal Jacket at 1,655 fps and 243 ft-lbs, designed for high-volume training and target shooting.

At $1.18 per round for 500 rounds, this is the 40-grain option in the category — heavier and slower than the 27-grain FNH loads, loaded to the same specifications as Federal’s Premium line.

Total Metal Jacket — Better Than FMJ for Indoor Ranges

Standard FMJ bullets expose bare lead at the base. At firing, this generates lead vapor at the muzzle — accumulating in range ventilation and on the floor behind the firing line.

The Federal American Eagle 5.7x28mm Total Metal Jacket completely encases the lead core — jacket over the base eliminates the exposed lead.

The result is less lead vapor at the firing point. Not lead-free (the core is still lead), but a meaningful reduction compared to standard FMJ.

For ranges that require TMJ rather than FMJ, the AE5728 is the specification answer. For shooters who prefer TMJ for routine range use, this is the 40-grain volume option.

40 Grains at 1,655 fps

The Federal American Eagle 5.7x28mm 40-grain load is slower and heavier than the 27-grain FNH variants (SS195LF: 2,050 fps; SS198LF: 2,480 fps).

At 243 ft-lbs it is the lowest energy in the 5.7×28mm cluster, but it matches the weight class of the Speer Gold Dot 40-grain defensive load.

For shooters who want to train with the same bullet weight as their defensive load (Speer Gold Dot 40gr), the AE5728 40gr TMJ is the matching range counterpart.

Frequently Asked Questions

What is Total Metal Jacket and how is it different from FMJ? A standard FMJ bullet leaves the lead base exposed. A TMJ bullet jackets the base as well, fully enclosing the lead core. At firing, the exposed lead base of an FMJ generates lead vapor; the TMJ’s enclosed base reduces that vapor. Both contain lead — TMJ is not lead-free.

Why is this load slower than the 27-grain FNH variants? The 40-grain bullet is significantly heavier than the 27-grain loads (SS195LF, SS198LF). Heavier bullets generally produce lower muzzle velocity in the same cartridge. The 40-grain weight matches the Speer Gold Dot 40gr defensive load, making AE5728 the natural training counterpart.

Why choose the 40gr AE over the 27gr FNH lead-free loads for indoor range use? The 27-grain FNH loads (SS195LF, SS198LF) are lead-free — no lead in the bullet at all. The AE5728 TMJ reduces lead vapor but still contains a lead core. For strict lead-free requirements, the FNH loads are the correct choice. For shooters who match bullet weight to their defensive load (40gr), AE5728 is the training answer.

Is this compatible with the FN Five-seveN, Ruger-57, and PS90? Yes — standard 5.7×28mm compatible with all commercial 5.7×28mm platforms. Confirm your specific platform before ordering.

Is the brass reloadable? Yes — brass casing, Boxer primer.

How many rounds is 500? 10 × 50-round boxes.

What’s the per-round cost? $590 / 500 = $1.18 per round.

What’s the muzzle energy comparison vs other 5.7×28mm loads here? AE5728 40gr TMJ: 243 ft-lbs. SS195LF 27gr Blue Tip: 282 ft-lbs. SS198LF 27gr Green Tip: ~369 ft-lbs. Speer Gold Dot 40gr: confirm on Speer’s page.
