The Piledriver is probably the most remarkable pellet from Hugh Earl’s legacy. It is an extremely accurate and heavy boat-tail pellet that provides outstanding downrange energy. This performance is mainly due to its favorable ballistic coefficient of 0.082 resp. 0.095.

Tests show that caliber.177 barrels from different manufacturers need Piledrivers with different body diameters. That is the reason why we offer the pellets in 4.50mm and 4.46mm body diameter.
The Piledriver is designed for PCP rifles and not effective in spring or gas-ram powered rifles.
