Winchester USA 223 Rem 45gr JHP Ammo - 40 Rounds Box

The Winchester USA 223 Rem 45gr Jacketed Hollow Point delivers precision terminal performance for varmint hunting and tactical applications. This ammunition combines Winchester's proven manufacturing standards with a lightweight 45-grain bullet optimized for rapid expansion and energy transfer.

What Makes This Different

The 45-grain jacketed hollow point design sets this load apart from standard FMJ offerings by providing controlled expansion upon impact. Winchester's USA line maintains consistent powder charges and primer seating for shot-to-shot reliability. The lightweight bullet achieves higher velocities than heavier projectiles, resulting in flatter trajectories and reduced wind drift at extended ranges.

Key Features

• 45-grain jacketed hollow point bullet for rapid expansion
• High-velocity loading optimized for flat trajectory
• Boxer-primed brass cases suitable for reloading
• Non-corrosive powder and primers for barrel longevity
• Factory-loaded to SAAMI specifications
• 40 rounds per box for extended range sessions
• Compatible with 5.56/.223 chambered rifles

This ammunition excels in varmint hunting scenarios where quick, humane kills are essential. The hollow point construction transfers energy efficiently to small game while the high velocity minimizes bullet drop at typical prairie dog and ground squirrel distances. Law enforcement agencies utilize similar loadings for patrol rifle applications where over-penetration concerns exist.
