Things I liked:good penetration for wood and steel can targets, makes even lower powered pistols into soup can destroyers. airgun version of AP round (armor piercing) looks like sabot tank round. leaves barrel clean, its lead free and can be handled with out hand washes. price is great. Things I would have changed:accuracy could use improvement, but its penetrating power makes up for its faults. would go from zinc formula to tungsten tips. What others should know:does well for accuracy more in pistols, any ultra light pellet is not for long range accuracy in riffles that break sound barrier (1100 fps) tests show tumble of the pellets on target.
