The RWS Biathlon Special Match .22 LR 40gr LRN delivers sub-zero temperature-stable subsonic precision engineered specifically for competitive biathlon, winter target disciplines, and small-bore precision shooting. Formulated with temperature-insensitive powder, a lead-free primer, and specialised cold-condition bullet lubrication, this ammunition prevents wax hardening and fouling build-up in freezing actions down to -20°C. With a standard 40-grain Lead Round Nose projectile leaving the muzzle at a subsonic 320 m/s, it eliminates transonic flight turbulence to maintain tight, repeatable groupings at standard 50-metre biathlon and target distances.

Key Features

• Subsonic Velocity Stability: Operates at a true subsonic muzzle velocity of 320 m/s (approx. 1,050 fps) to avoid transonic turbulence barriers and ensure consistent aerodynamics.
• Cold-Weather Lubricant: Specially formulated bullet coating prevents lubricant hardening and chamber fouling in sub-zero environments down to -20°C.
• Temperature-Insensitive Propellant: Delivers uniform combustion and shot-to-shot consistency across harsh freezing conditions.
• Lead-Free Primer Compound: Formulated to reduce heavy metal emissions during high-volume indoor and outdoor shooting sessions.
• Optimised Platform Compatibility: Chambers reliably in .22 LR bolt-action match rifles and straight-pull biathlon actions.

Who is the RWS Biathlon Special Match .22 LR for?

• Competitive Biathletes — Requires stable ignition down to -20°C and a subsonic muzzle velocity of 320 m/s to prevent transonic turbulence at standard 50-metre biathlon target systems.
• Small-Bore Match Shooters — Delivers shot-to-shot velocity consistency using a 40-grain Lead Round Nose projectile with a 0.136 ballistic coefficient for 50-metre prone and three-position competition.
• Cold-Weather Precision Marksmen — Utilises cold-condition lubricant and temperature-stable powder in this rimfire match ammunition to prevent action jamming and velocity loss in ambient temperatures as low as -20°C.

Less suitable for: Target disciplines beyond 100 metres where subsonic drop limits trajectory performance, warm-weather matches where standard match ammunition without specialised cold lubricants is preferred, or ethical game hunting where expanding hollow-point hunting ammunition is required.
