RPS Big Bore .728 – heavy-duty airgun pellets for specialised big bore applications

These RPS Big Bore projectiles feature an 18.3mm calibre and weigh 640 grains, making them among the heaviest airgun ammunition available. The Flat Nose (FN) design creates maximum frontal surface area, ideal for target shooting and applications requiring maximum energy transfer. Made from lead, these pellets require special .728 calibre PCP air rifles with minimum 300 joule output.

Construction and materials

Each pellet weighs 640 grains – approximately 50 times heavier than standard 4.5mm pellets. The lead construction ensures proper bore seal and shape retention during flight. The Flat Nose design features a flat front surface that maximises impact energy transfer. Supplied in packs of 50 pellets with silver finish.

Application and use

Designed for experienced shooters using specialised .728 calibre PCP air rifles. These heavy projectiles excel in target shooting and specialist applications where precision and power combine. The extreme weight provides exceptional flight stability, though the ballistic curve differs significantly from lighter projectiles.

Integration and compatibility

Compatible exclusively with Pre-charged pneumatic (PCP) air rifles chambered for 18.3mm / .72 calibre. Systems must deliver minimum 300 joule output to effectively shoot these 640 grain projectiles. A chronograph helps optimise velocity and consistency for your specific airgun setup.
