The RWS Premium Line R100 is match-grade, supersonic .22 Long Rifle ammunition engineered for competitive target disciplines. Featuring precision-formed 40-grain Lead Round Nose (LRN) projectiles and uniform propellant charges, each cartridge produces a factory-measured muzzle velocity of 345 m/s (1,132 fps) and 155 Joules (114 ft-lbs) of muzzle energy from a standard 650 mm test barrel. This higher velocity profile provides flatter trajectories and dependable kinetic impact across 50-metre and 100-metre distances.

Key Features

• Match-Grade Tolerances: Manufactured with uniform brass cases, consistent primers, and tight powder charges to minimise shot-to-shot velocity variation.
• Supersonic Velocity: Achieves a muzzle velocity of 345 m/s (1,132 fps), delivering higher kinetic energy on impact than standard subsonic match loads.
• Precision Lead Projectile: Fitted with a 40-grain (2.60 g) Lead Round Nose bullet designed for aerodynamic stability in smallbore competition barrels.
• Broad Compatibility: Standard .22 LR chamber interface functions reliably in match rifles, target pistols, and biathlon platforms.

Who is the RWS R100 .22 LR 40gr Ammunition for?

• Competitive metallic silhouette shooters — requires the 155 Joules of energy and 345 m/s velocity generated by this rimfire match ammunition to reliably topple heavy steel targets out to distance.
• 50 m and 100 m smallbore target competitors — relies on the consistent 40-grain projectile weight and flat supersonic trajectory of this rimfire match ammunition to maintain tight group dispersion across standard match distances.
• Biathlon and summer biathlon competitors — benefits from the 345 m/s muzzle velocity of this rimfire match ammunition to ensure dependable cycling and consistent ballistic performance in freezing ambient conditions.

Less suitable for: Target shooting past 100 m where specialized long-range cartridges with heavier projectiles provide flatter trajectories, or disciplines requiring strictly subsonic flight to avoid transonic buffeting, where standard subsonic match ammunition is better suited.
