Extend your training sessions and pick yourself up 500 rounds of Professional Line pellets from RWS. These pellets can be used in all .177 caliber (4.5mm) air guns, and are specially designed for high penetration. The unique Wadcutter design of these pellets protects from wind and provides optimal stabilization within the barrel, resulting in maximum velocity and accuracy. Each of these professional grade pellets were regularly inspected during production to ensure size consistency and are crafted from the best material available. New optimized surface treatments leave these pellets with a permanent bright and shiny appearance, and help to prevent resistance within the barrel. The seamless design of these pellets ensure they won't break apart in even the most powerful of air rifles.
