The Norma TAC-22 Subsonic .22 LR 40 Grain Lead Hollow Point ammunition is designed for quiet, low-signature rimfire shooting, small game harvesting, and vermin control. Operating at a muzzle velocity between 1,017 fps and 1,033 fps, this round remains below the speed of sound to eliminate the supersonic crack. Paired with a 40-grain Lead Hollow Point (LHP) projectile, it delivers reliable terminal expansion and energy transfer on target within standard rimfire engagement distances. It is compatible with firearms chambered in .22 Long Rifle, offering optimal consistency across bolt-action, lever-action, and manual-loading platforms.

Key Features

• Subsonic Velocity: Travels at 1,017 fps to 1,033 fps to prevent sonic crack, making it suited for sound-moderated shooting and low-noise environments.
• Lead Hollow Point Bullet: The 40-grain LHP profile expands rapidly on impact to deliver 92 ft-lbs to 95 ft-lbs of muzzle energy into small pests.
• European Rimfire Priming: Consistent priming and uniform lubrication ensure reliable ignition and smooth cycling across standard .22 LR chambers.
• Suppressor Optimised: Engineered specifically for reduced auditory signature when paired with sound moderators and suppressed platforms.

Who is the Norma TAC-22 Subsonic 40gr HP for?

• Small Game Hunters — requires a 40-grain hollow point projectile that expands reliably on targets under 5 kg within a 25 to 75-metre operating range while maintaining low acoustic output through a suppressed rifle.
• Noise-Sensitive Pest Control Shooters — relies on true subsonic rimfire ammunition delivering muzzle velocities between 1,017 fps and 1,033 fps to eliminate supersonic crack when managing vermin in rural-fringe or peri-urban areas.

Less suitable for: Long-range shooting beyond 75 to 100 metres where trajectory drop increases, or target species exceeding 5 kg; these applications require high-velocity .22 LR, .22 WMR, .17 HMR, or centerfire calibres such as .223 Remington.
