5.56 Sterling 55gr SP 30rds

5.56 Sterling 55gr SP 30rds is a high-quality, economical 5.56×45mm NATO load from Sterling Ammunition, featuring a 55-grain soft-point (SP) bullet designed for excellent terminal performance on medium game, varmints, and defensive use.

Key specifications:

• Caliber: 5.56×45mm NATO / .223 Remington compatible
• Bullet: 55 grain soft-point (SP) — lead core with exposed lead tip for controlled expansion and rapid energy transfer
• Muzzle velocity: ≈3,100–3,200 fps (from a 20-inch barrel)
• Muzzle energy: ≈1,180–1,250 ft-lbs
• Ballistic coefficient (G1): ≈0.243 — good flat trajectory out to 300 yards
• Case: New brass, boxer-primed, reloadable
• Quantity: 30 rounds per box
• Performance: Rapid expansion on impact, reliable feeding in AR-15 platforms, and good barrier penetration while maintaining effective terminal ballistics on soft tissue

This load excels for varmint hunting (coyotes, prairie dogs), predator control, home defense, and range/plinking where you want more terminal effect than FMJ without stepping up to heavier hollow-points or bonded rounds. The soft-point profile delivers consistent expansion and energy dump while remaining economical for high-volume shooting.

A reliable, expanding 55gr soft-point 5.56 load — perfect for hunting, varmint control, and defensive use at a great price.
