The FN SS201 GUNR 5.7x28mm 40-grain full metal jacket round from FN Herstal delivers the high-velocity, low-recoil performance that serious shooters ask for, offering 1700 fps and roughly 257 ft-lbs from a Five-seven and up to 2040 fps and 370 ft-lbs from a PS90 to extend effective range and flatten trajectories for target and training sessions. As part of FNs SS201/GUNR series, this ammunition matches the felt recoil, velocity and accuracy shooters expect from the platform and cycles reliably across all 5.7x28mm firearms, including pistols and rifles, which makes it excellent for long strings on the range where shooter control and quick follow-up shots matter. The 40 gr FMJ profile feeds cleanly and the brass-cased, boxer-primed construction provides consistent ballistics and reduced fouling for smoother operation, while the cartridges design yields reduced wind drift and practical terminal performance useful for tactical applications and defensive-minded training drills. If you run SS197SR in competition or duty practice, youll find comparable handling and accuracy from the FN SS201, making it a go-to choice for shooters who want dependable, cost-effective target ammunition that translates well between handgun and rifle platforms.
