Fiocchi Range Dynamics 5.7x28mm 40gr FMJ

Fiocchi Range Dynamics 5.7x28mm is the value answer to 5.7's biggest problem: ammo cost. Sold in 150-round bulk packs at roughly $0.45 per round, it undercuts FN's brass-case SS197SR and most other factory 5.7 loads by a wide margin, which makes it the practical choice for shooters who actually want to train with their 5.7 pistol rather than ration it.

The 40gr FMJ bullet leaves the muzzle at 1,700 fps. Performance is unremarkable by design; this is a clean-shooting, reliable plinking and practice load, not a defensive cartridge. Fiocchi manufactures it on brass cases, so it reloads, and the 150-round packaging is built for range days where you burn through ammo faster than a 50-round box allows.

Even at value pricing, understand that 5.7x28mm has no genuinely cheap option. Range Dynamics is the floor of the market, and that floor is still roughly double the cost of 9mm range FMJ. If you shoot 5.7 in volume, this is where your practice budget goes; reserve the more expensive FN and defensive loads for zeroing and carry.
