Big Bore FN .510 – heavy-duty slugs for high-power PCP platforms

These RPS Big Bore slugs deliver .51 caliber projectiles weighing 440 grains for powerful PCP air rifles. The Flat Nose (FN) design maximizes energy transfer on impact while the heavy projectile mass provides superior wind resistance. Packaged in 100 pieces, these slugs are engineered for the .50 Hammer platform and similar high-energy systems.

Construction and materials

Each slug is precision-formed from lead with a silver finish, weighing 440 grains. The Flat Nose profile creates a large frontal surface area for maximum impact energy transfer. At 13mm diameter, these projectiles rank among the heaviest in their class, providing the mass necessary for stable flight trajectories and deep penetration at extended ranges.

Application and use

Designed for experienced shooters operating Pre-charged pneumatic (PCP) systems with minimum 200 joule output. These slugs excel in precision shooting scenarios up to 100 meters, particularly in windy conditions where lighter projectiles suffer from drift. The heavy weight makes them ideal for long-range target work where both accuracy and stopping power are critical.

Integration and compatibility

Specifically engineered for .50 Hammer platforms and compatible high-power PCP systems. The .51 caliber specification requires appropriate barrel sizing for optimal performance. These slugs perform best at higher pressure settings to maintain flat trajectories given their substantial 440 grain weight.
