450 Rounds of 5.7x28mm Ammo by Fiocchi – 40gr FMJ

Once in a while someone asks us if they can fire 5.7x28mm ammunition in their 22 LR firearm. We gently guide them to a more suitable part of our website, because we want to make sure the Fiocchi Range Dynamics 5.7x28mm falls in the hands of the Ruger 5.7 and FN Five-seveN owners who really need it!

This is a range cartridge to the bone. Its 40 grain full metal jacket projectile is engineered to promote a cleaner barrel and deliver a pleasingly flat trajectory. It hasn’t got an expensive polymer tip, and is accordingly incapable of creating a wound channel that is significantly wider than 0.224” in diameter. Fiocchi doesn’t sneak steel into their FMJs, which makes this ammo bona fide nonmagnetic.

Fiocchi creates this ammo’s high-quality components and assembles them at their factory in Ozark, MO. Fresh-off-the-presses brass cases. Reliable and corrosion-free Boxer primers. Fast-burning propellant. Truly dependable and fun-to-fire stuff, right here!
