Winchester Lake City Rifle Ammunition .223 Rem 55 gr. FMJ 600/ct Case (4-150 round boxes)

Winchester Lake City rifle ammunition in .223 Rem is a reliable, cost-effective choice for shooters who log serious range time. Built around a 55-grain full metal jacket projectile, this load delivers consistent performance across AR platforms, bolt rifles, and other .223 rifles. The 600-round case—packed as four 150-round boxes—is built for high-volume shooters: competitive shooters, trainers, and hunters who want to practice without breaking the bank or making repeated trips to restock.

Lake City ammunition is manufactured to military specifications and has earned its reputation in professional and civilian hands alike. The full metal jacket design means clean, predictable ballistics and reliable feeding through semi-automatic and bolt-action rifles. Whether you're zeroing a new optic, running drills at the range, or stocking up for the season, this case quantity gives you the volume you need without the premium pricing of smaller boxes.

The 55-grain bullet weight is the sweet spot for .223 rifles—light enough for flat trajectory and fast splits, heavy enough to stabilize reliably in most .223 barrels. Each box contains 150 rounds, so you get four manageable packs in a single case order, making storage and portioning straightforward. If you run .223 rifles regularly, this is the kind of ammunition that pays for itself in shooting consistency and convenience.
