Big Bore HP Pellets – heavy-calibre ammunition for high-power PCP systems

These Big Bore hollow point pellets feature a substantial .51 calibre (13mm) diameter and weigh 355 grains, designed specifically for high-powered PCP air rifles. The hollow point design ensures optimal energy transfer on impact, making them suitable for long-range precision shooting where maximum power delivery is essential.

Construction and materials

Manufactured from lead with a silver finish, these pellets maintain consistent weight distribution across the 355-grain projectile. The hollow point nose design balances aerodynamic efficiency with expansion characteristics. Each package contains 100 pellets, manufactured to tight tolerances for reliable performance.

Application and use

These heavy pellets are engineered for Pre-charged pneumatic (PCP) air rifles capable of handling large-bore ammunition. The .51 calibre specification requires compatible barrel dimensions and sufficient power output to stabilise the heavy projectile. Optimal performance typically requires PCP systems generating 300+ joules of muzzle energy.

Integration and compatibility

Designed exclusively for air rifle platforms with .510/13mm bore dimensions. The 355-grain weight demands adequate barrel twist rates and power levels found in dedicated big-bore PCP systems. Chronograph testing is recommended to verify optimal velocity and energy output for your specific rifle configuration.
