Hrndy Sf 223rem 55gr Cx 20/200

The Hornady SF 223 Rem 55gr CX is a high-performance rifle cartridge designed for precision shooting and tactical applications where barrier-blind, lead-free performance is required. This ammunition ships in convenient 20-round boxes with 200-round cases available, making it suitable for both range training cycles and duty use.

The 55-grain bullet weight represents the optimal balance for .223 Remington performance across modern carbines and rifle platforms. Hornady's CX (Copper eXpanding) projectile uses a monolithic copper construction that eliminates lead entirely while maintaining consistent velocity and expansion. The 223 Rem 55gr load delivers reliable terminal performance at typical engagement distances from 25 to 300 yards, a practical range envelope for law enforcement patrol carbines, AR-15 rifle systems, and civilian defensive shooting. The cartridge generates predictable recoil characteristics that support rapid follow-up accuracy, particularly important in low-light conditions or high-stress scenarios where shot placement determines outcomes.

This ammunition is engineered for shooters who operate under ammunition restrictions favoring non-lead projectiles—common in controlled shooting environments, ranges with environmental constraints, and jurisdictions implementing lead-free mandates. The 223 Rem cartridge itself remains the dominant intermediate rifle caliber for semi-automatic rifle owners, law enforcement carbine programs, and military-pattern rifle enthusiasts. Hornady SF ammunition (Straight Fire) emphasizes component consistency and chamber reliability across a wide range of AR platform tolerances. Serious shooters stock this ammunition for practice, qualification, and duty applications where terminal performance and lead-free compliance are non-negotiable.
