The RWS R50 .22 LR Rimfire Ammunition (MPN: 2134187) is match-grade ammunition engineered for elite competitive precision shooting. Operating as part of the RWS Premium Line, each round features a 40-grain (2.6 g) Lead Round Nose (LRN) projectile with an overall cartridge length of 25.4 mm. Developed with uniform primer distribution and consistent propellant charges, it delivers a factory-tested muzzle velocity of 330 m/s (approx. 1,080–1,090 fps) from a 650 mm test barrel, maintaining a velocity of 271 m/s at 91 metres to prevent transonic turbulence across competitive target distances.

Key Features

• Consistent Ballistic Velocity: Produces a muzzle velocity of 330 m/s to stay beneath standard transonic thresholds, eliminating shockwave disruption across 50-metre trajectories.
• Precision Lead Round Nose: Features a solid 40 gr Lead Round Nose bullet profile designed for clean paper punching and tight group dispersion.
• Strict Manufacturing Tolerances: Loaded with uniform primer distribution and matched powder charges to minimize shot-to-shot standard deviation.
• Target Chamber Compatibility: Engineered to chamber reliably in standard .22 LR precision target handguns, smallbore rifles, and match-grade action barrels.
• Standard Box Count: Packaged in 50-round individual boxes for organized range session tracking and lot testing.

Who is the RWS R50 .22 LR ammunition for?

• ISSF 50m rifle and pistol competitors — requires the 330 m/s muzzle velocity and 40 gr bullet weight of this rimfire match ammunition to maintain subsonic stability and tight group dispersion across 50-metre prone, 3-position, and free pistol courses of fire.
• Smallbore benchrest shooters — relies on the consistent 40-grain solid lead profile and minimal shot-to-shot velocity variance across 50-round lots to minimize vertical stringing on precision paper targets.

Less suitable for: Target shooting beyond 100 metres where higher-velocity match rounds or larger calibres are required to resist wind drift, or hunting applications requiring terminal expansion, where dedicated hollow-point subsonic or high-velocity ammunition is better suited.
