Bulk 5.7x28mm Ammo

Overview of 5.7x28mm Ammo

5.7x28mm is a small, high-velocity cartridge developed by FN Herstal for the P90 personal defense weapon and the Five-seveN pistol. It fires a light .224-inch bullet, usually 27 to 40 grains, at up to 2,000 fps or more from a pistol. The result is a flat-shooting round with very light recoil and high magazine capacity, typically 20 rounds in a pistol and 50 in a P90 or PS90.

Once limited to FN guns, 5.7x28 now runs in the Ruger-57, Smith & Wesson M&P 5.7, Palmetto State Armory Rock and Dagger, and a range of carbines. That wider adoption has made 5.7 ammo easier to find and more affordable in bulk.

Frequently Asked Questions

Is 5.7x28 good for self-defense?

It can be, with a load designed for defense. Purpose-built loads like Speer Gold Dot 40gr and Hornady Critical Defense 40gr FTX expand and penetrate more consistently than lightweight range ammo. The low recoil and high capacity of 5.7 pistols make fast, accurate follow-up shots easy.

What is the difference between SS195LF and SS198LF?

Both are FN 27gr lead-free hollow point loads sold to civilians. SS195LF is FN's standard range and training load. SS198LF uses the same weight bullet with a different hollow point design. Both are popular choices for practice in Five-seveN pistols and PS90 carbines.

Is 5.7x28 armor piercing?

No. The armor-piercing SS190 load is restricted to military and law enforcement sales. The 5.7x28 ammunition sold to civilians, including FN SS195LF, SS198LF, and SS200, Speer Gold Dot, and Hornady Critical Defense, uses conventional hollow point or soft bullets.

More About 5.7x28mm Ammo

FN Herstal developed 5.7x28mm in the late 1980s and early 1990s in response to a NATO request for a new personal defense weapon cartridge that could defeat body armor at close range. The P90 came first in 1990, followed by the Five-seveN pistol in the late 1990s, so both a carbine and a pistol could share the same ammunition.

For civilians, the appeal of 5.7 is flat trajectory, light recoil, and high capacity in a lightweight gun. For years the cartridge was held back by expensive ammunition and few gun options, but that changed when Ruger introduced the Ruger-57 in 2019, followed by Smith & Wesson, Palmetto State Armory, and others.

Today 5.7x28 is one of the fastest-growing handgun calibers in the country, and factory ammunition is available from FN, Speer, Hornady, Fiocchi, Federal, and more.
