Fiocchi Ultrasonic .22 LR 40 gr High-Velocity Rimfire

Fiocchi Ultrasonic .22 LR is a high-velocity copper-plated lead round nose cartridge from Fiocchi of Italy — one of Europe's oldest ammunition manufacturers operating continuously since 1876 in Lecco, northern Italy. The Ultrasonic designation refers to the cartridge's high-velocity specification, pushing a 40 grain projectile at velocities that provide reliable function across a wide range of semi-automatic and bolt-action .22 LR platforms.

Fiocchi's manufacturing standards reflect their European competition and military supply heritage — consistent primer ignition, tight velocity tolerances, and reliable feeding across diverse firearm designs.
