• Copper-plated hollow point bullet reduces lead fouling and buildup in silencer baffles and ports, extending suppressor cleaning intervals
• Hollow point design optimized for maximum terminal effectiveness at subsonic velocities, where standard bullet expansion can be inconsistent
• Brass casing provides reliable feeding, smooth extraction, and dimensional consistency across the full 225-round pack

Practical Benefits

• The 225-round count gives you a serious training or small game session without stopping to reload your range bag or ammo supply
• Subsonic velocity makes this load a natural fit for suppressed 22 LR rifles and pistols, keeping your host firearm hearing-safe without a booming crack downrange
• The copper-plated hollow point design works with a wide range of 22 LR platforms and keeps your suppressor cleaner between sessions
• Ideal for pest and small game control where a quiet shot matters more than high velocity, and for training new shooters in a low-noise environment
• Your investment in a quality 22 suppressor performs at its best when the ammunition is engineered from the ground up to stay subsonic, and the Remington Subsonic Rimfire (21249) delivers that consistency round after round.

The Remington Subsonic Rimfire 22 LR 40 Grain Copper Plated Hollow Point (21249) is a proven platform for suppressed rimfire shooters, small game hunters, and anyone who needs quiet, consistent performance from a 22 Long Rifle cartridge.
