The Norma Xtreme LR-22 .22 LR 43gr Lead Round Nose ammunition is engineered specifically for extended-range and precision rimfire target shooting. Featuring a heavy 43-grain projectile with an elongated ogive and a patented streamlined "rocket-tail" boat-tail base, this cartridge reduces aerodynamic drag and minimises crosswind drift downrange. Loaded to a muzzle velocity of 1,165 fps (~355 m/s) with consistent powder charges for low velocity standard deviation, it extends the effective operating envelope of precision rimfire platforms beyond standard 50-to-100-metre distances out to 300 to 600 yards (274 to 548 metres).

Key Features

• Aerodynamic 43-Grain Projectile: Built with an elongated nose profile and a streamlined boat-tail base to decrease drag and improve ballistic efficiency over long distances.
• Consistent Downrange Velocity: Delivers a muzzle velocity of 1,165 fps (~355 m/s) with uniform powder charges to maintain vertical group consistency downrange.
• Precision Rimfire Compatibility: Functions in standard .22 LR chambered bolt-action rifles, semi-automatic rimfire firearms, and precision match platforms.
• Box Packaging: Supplied in standard boxes of 50 rounds for competition and practice sessions.

Who is the Norma Xtreme LR-22 43gr LRN for?

• NRL22 and PRS Rimfire Match Competitors — Requires tight vertical dispersion across variable distances, which this rimfire precision target ammunition provides via consistent powder charges and a heavy 43 grains projectile travelling at 1,165 fps.
• Extreme Long-Range Rimfire Target Shooters — Needs aerodynamic stability to engage targets from 300 yards out to 600 yards, supported by this .22 LR cartridge's streamlined boat-tail bullet profile that resists wind drift at extended ranges.

Less suitable for: Close-range small-game hunting or pest control requiring terminal expansion, where a hollow-point 36-to-40-grain hunting projectile is better suited than this non-expanding target round; and shooters requiring strictly subsonic performance to avoid sonic crack transition, who should select dedicated subsonic rimfire ammunition operating at 1,050 fps or lower rather than this 1,165 fps load.
