Big Bore FN .510 / 13mm 565gr RPS – heavy-duty slugs for extreme power applications

These Big Bore slugs from RPS are engineered for high-powered PCP air rifles. With a calibre of .510 (13mm) and weighing 565 grains, these Flat Nose projectiles rank among the heaviest airgun ammunition available. The flat-nose design ensures maximum energy transfer on impact, making them particularly suitable for long-range shooting with systems exceeding 300 joules.

Construction and materials

Manufactured from lead with a silver finish, each slug measures 13mm (.510) in diameter. The Flat Nose (FN) profile provides an optimal balance between aerodynamics and impact force. At 565 grains, these projectiles maintain exceptional energy retention over extended distances while delivering stable flight characteristics even in challenging conditions.

Application and use

These slugs are designed for experienced shooters operating powerful PCP systems like the UMAREX Hammer .50. They excel in precision shooting beyond 100 metres and technical challenges requiring maximum impact force. A minimum of 300 joules is necessary to utilise the full potential of these heavy projectiles.

Integration and compatibility

Specifically calibrated for .51 calibre big bore Pre-charged pneumatic (PCP) air rifles. Each package contains 100 pieces, providing ample ammunition for extended shooting sessions. Using a chronograph is recommended to accurately monitor energy output when firing these substantial projectiles.
