FN GUNR SS201 5.7x28mm 40gr FMJ

FN GUNR SS201 is the factory-direct 5.7x28mm range load from the company that invented the cartridge. It sits alongside FN's SS197SR sporting round in the current lineup, with the DFNS SS200 as the defensive companion and SS195LF as the lead-free option. For shooters who want their practice ammo to come from the same source as the platform, this is the default training round.

The 40gr FMJ leaves a Five-seveN pistol at 1,700 fps for 257 ft-lbs, and a PS90 carbine barrel pushes it to 2,040 fps and 370 ft-lbs. It is a clean-burning, non-corrosive, boxer-primed brass load that reloads, so it does double duty for shooters who roll their own. Performance is unremarkable by design; this is a function-test and volume-practice cartridge, not a defensive round.

At roughly $0.61 per round it undercuts most brass-case 5.7 competitors and matches the value tier that Fiocchi Range Dynamics established. The real advantage is supply stability: FN controls its own production, so GUNR SS201 tends to stay on shelves when third-party 5.7 dries up. Buy it for the reliable long-term feed.
