DoubleTap developed the Colt Defense .223 Remington 62-grain load (brand part no. 223R62CT) from the ground up to be one of the strongest defensive options available in .223/5.56, and the solid-copper hollow-point bullet backs that claim up. The lead-free, monolithic copper build opens reliably at typical carbine velocities, driving controlled expansion and fast energy transfer instead of the narrow wound channel a full metal jacket leaves behind. Because the bullet is a single piece of copper rather than a jacketed lead core, it resists fragmenting and holds together through barriers a standard FMJ or soft point might not survive. DoubleTap builds this specifically for home-defense and duty-style carbines chambered in .223 Remington or 5.56 NATO, not for the range. Twenty rounds ship per box for anyone who wants their defensive rifle loaded with something purpose-built rather than repurposed target ammo.

Key Specifications

• The chambering is .223 Remington/5.56 NATO, standard for AR-platform defensive carbines.
• The bullet weighs 62 grains, a mid-weight choice that balances velocity and energy transfer.
• Construction is solid copper, a monolithic, lead-free build rather than a jacketed lead core.
• The tip is a hollow point, driving controlled expansion and rapid energy transfer at impact rather than deep, narrow FMJ-style penetration.
• The one-piece copper build resists fragmenting, holding together through barriers that can break apart a jacketed bullet.
• DoubleTap developed this as a purpose-built defensive load, not a range or target loading.
• Cost runs about $1.38 per round, reflecting the solid-copper defensive construction.
