RWS Umarex 2251543 .25 Cal CO2 Cartridges 18-Round Pack

The RWS Umarex 2251543 delivers consistent power for .25 caliber air pistols and rifles with an 18-cartridge supply that ensures extended shooting sessions. These premium CO2 cartridges maintain reliable pressure output across temperature variations, providing the consistent velocity needed for accurate target shooting and training applications.

What Makes This Different

RWS CO2 cartridges undergo rigorous quality control testing to ensure uniform pressure delivery and leak-free performance. Each 12-gram cartridge contains high-purity CO2 that burns cleaner than standard alternatives, reducing residue buildup in air gun mechanisms. The precision-manufactured threading creates secure seals that prevent pressure loss during storage and use.

Key Features

• 18-count pack provides extended shooting sessions without frequent reloading
• 12-gram CO2 capacity delivers consistent pressure for reliable cycling
• High-purity CO2 formula reduces fouling and extends equipment life
• Precision threading ensures leak-proof seal in compatible air guns
• Temperature-stable formula maintains performance in varying conditions
• Compatible with most .25 caliber CO2-powered air pistols and rifles
• Individual cartridge packaging prevents contamination and damage

Performance remains consistent across the cartridge's full capacity, maintaining velocity within 2% variance from first shot to last. The high-purity formulation reduces the carbon buildup that can affect accuracy and cycling reliability in precision air guns. These cartridges perform reliably in temperatures ranging from 32°F to 100°F, making them suitable for indoor ranges, outdoor training, and competitive shooting events.
