The Norma Range & Training Rifle Ammunition 5.56x45 NATO 55gr FMJ 3250 fps 250/rd is purpose-built for shooters who demand consistent performance from their AR-15 or M4 pattern rifles. Loaded to European manufacturing standards, this brass-cased cartridge uses a 55 grain full metal jacket bullet to deliver reliable cycling and repeatable accuracy across extended practice sessions.

This 5.56x45 NATO load produces a muzzle velocity of 3250 fps and 1289 ft-lbs of energy from a standard test barrel, matching the velocity profile many gas-operated platforms are tuned around. The reloadable brass case offers smoother feeding and extraction than steel alternatives, while carefully controlled powder charges and primer seating help maintain uniform shot-to-shot performance. Packed in a 250-round box, it is well suited for focused range work, carbine classes, and general training, backed by Norma Ammunition’s reputation for precision and consistency.
