Prometheus, a unique 2 piece pellet
The Prometheus are saboted pellets having a 2 piece construction, lead fore-end with a plastic skirt. The Prometheus is an expensive pellet though they do shoot exceptionally well in some air rifles, as they display a low Standard Deviation through their use of a plastic skirt that improves the Ballistic Coefficient and pellet weight consistency.
I would only recommend the Prometheus pellet for you guys into Target Shooting although they have been touted as a hunting pellet. If you are into hunting, H&N and JSB have a good range of hunting pellets for you.
Price $17.60 per tin of 125.
