5.7x28mm – 30 gr JHP – FN SS200 (10700029) – 500 Rounds

FN designed the SS200 as a dedicated personal defense load for the 5.7x28mm. This listing is FN SS200 5.7x28mm 30 grain jacketed hollow point ammo, FN product number 10700029, sold as a 500 round case. It is intended for Five-seveN, PS90, and other 5.7 owners who want an expanding defensive load built by the company that developed the cartridge, and who want enough of it to test and carry.

FN lists the SS200 at 1,894 fps with 239 ft-lbs of muzzle energy from the Five-seveN pistol, and 2,240 fps with 334 ft-lbs from the PS90 carbine. The bullet uses a copper jacket over a frangible copper-tin core, which FN says is designed to expend energy quickly and expand consistently. FN states the load meets the FBI test protocol and was independently tested. This is a self defense round, so use a less expensive FMJ or training load for routine range practice.

It fits firearms chambered in 5.7x28mm, including the FN Five-seveN and PS90, Ruger-57 and LC Carbine, Smith and Wesson M&P 5.7, Palmetto State Armory Rock and 5.7 uppers, and Kel-Tec P50 and CP33 variants. A common question is whether 5.7x28mm is the same as 5.56 or 22 Magnum. No. It is a unique bottleneck cartridge that only fits firearms chambered for it. Another common question is how carbine velocity compares. A longer barrel adds roughly 350 fps, according to FN data, which changes trajectory.

FN SS200 is new production ammunition, not reloads. Cases are brass with boxer primers. This listing ships as one 500 round case under FN product number 10700029, all from one lot, so the rounds you test for function and point of impact are the same rounds you carry. Rotate carry ammunition periodically and use the rest of the case for confirmation shooting. Store the case in a cool, dry place to keep it ready for years.
