FX Hybrid Cal. .25/6.35 mm 26.3 grain slugs are a hybrid or cross-over between a conventional pellet and a slug.
Pellets with a diabolo shape will shape themselves perfect to the rifling of the barrel and have a low bearing surface. Their shape however, gives them a low ballistic coefficient making them susceptible to wind and lets them lose their energy fairly quick.
Slugs however, have a much higher ballistic coefficient which lets them maintain their energy better. The high weight and large bearing surface (extra friction) make for a need for substantial power to be able to drive them in a way that does justice to their properties.
The FX Hybrid Cal. .25/6.35 mm 26.3 grain slugs have the external dimensions of a slug with a high ballistic coefficient, but are completely hollow and feature a deep base. This makes them lightweight. Their shape provides a perfect balance between friction and bearing surface.
This combination of properties make the FX Hybrid slugs fly in a trajectory that’s more flat than conventional pellets and they’re also less prone to wind deviation. Because of the higher retaining energy they are very suitable for longer distances and the hollow point allows for a great expansion.
The other advantage of these FX Hybrid Cal. .25/6.35 mm 26.3 grain slugs is the fact they are developed with all PCP air rifles in mind, not only the extremely powerful or those featuring a slug liner.
