RPSolutions 12.7mm / .50 Hollow Base 205gn – heavy slug for large-calibre PCP air rifles

The RPSolutions 12.7mm / .50 Hollow Base is a large-calibre slug designed for high-power PCP air rifles. With a calibre of 12.7 mm / .50, a projectile weight of 205 grain, and a pack size of 100 pieces, this slug is engineered for stable, consistent performance in heavy air rifle setups. The hollow base improves bore sealing and supports reliable gas pressure behind the projectile.

Construction and materials

This slug is produced by RPS with a hollow base profile that enhances obturation inside the barrel. The substantial mass of 205 grain contributes to strong energy retention at longer distances, while the calibre of 12.7 mm / .50 places it firmly in the heavy projectile segment. The shape and weight distribution are aimed at predictable flight behaviour and consistent shot-to-shot results.

Application and use

This ammunition is intended for long-range shooting with large-calibre PCP air rifles. It suits experienced PCP shooters and precision users who have tuned their systems for heavy projectiles. Performance is optimal in rifles delivering 300J or more, where the slug's mass can be fully utilised for stable trajectories and effective energy transfer on target.

Integration and compatibility

The slug is compatible with PCP air rifles chambered in .50 / 12.7 mm. Because barrel specifications vary between platforms, testing different grain weights with a chronograph is recommended to determine the optimal match for a specific rifle and to fine-tune power settings for consistent muzzle energy.
