FN engineered the DFNS SS200 from the ground up as a dedicated personal defense round, setting it apart from 5.7x28mm training and sporting ammunition. The 30-grain jacketed hollow point bullet uses a unique copper-tin powdered core designed to fragment and expend energy quickly upon impact, creating controlled expansion and rapid wound cavity formation.
This is the first 5.7x28mm cartridge specifically optimized for personal defense rather than adapted from a training or target load. The brass casing with boxer primer ensures dependable cycling and reloadability, while the frangible core technology distinguishes this round from heavier, slower-expanding 5.7x28mm defensive options. The DFNS SS200 meets FBI test protocols for penetration and expansion, delivering both reliability in 5.7x28mm platforms and terminal performance designed for barrier-blind performance.
Each 500-round case breaks down into ten 50-round boxes for convenient storage and range sessions. Published specifications list 1,894 feet per second velocity from a pistol platform with 239 foot-pounds of muzzle energy. When fired from longer-barreled carbines like the PS90, velocities climb to approximately 2,240 fps with 334 foot-pounds of energy.
The SS200 cycles reliably in all modern 5.7x28mm firearms including the FN Five-seveN pistol, FN PS90 rifle, Ruger 57, and other contemporary 5.7x28mm platforms. The ammunition's design prioritizes consistent feeding and function across these firearms, making it a dependable choice for users who value ammunition that works the first time, every time.
The DFNS SS200 was engineered specifically for personal defense from the ground up, not adapted from training or target ammunition. Its unique frangible copper-tin powdered core is designed to fragment rapidly upon impact, creating controlled expansion and energy transfer. It's the only 5.7x28mm round FN developed with defense as the primary purpose.
The DFNS SS200 is designed for reliable cycling in all modern 5.7x28mm platforms including FN Five-seveN pistols, FN PS90 rifles, Ruger 57, and other contemporary 5.7x28mm firearms. The brass case and boxer primer ensure dependable feeding and function.
From a pistol with a standard barrel, the DFNS SS200 achieves approximately 1,894 fps. When fired from longer-barreled carbines like the PS90, velocity increases to around 2,240 fps due to the longer barrel providing additional acceleration. Your specific results will depend on barrel length and other firearm-specific factors.
Yes, the DFNS SS200 comes in reloadable brass cases with a boxer primer, making it suitable for reloaders. However, always follow proper reloading safety procedures and consult reliable reloading data for 5.7x28mm specifications.
