The product is a 22 caliber 20 grain Hollow Point hand-swaged slug Pellet made in the USA.0.217 hand swaged cup base, 100 ct. and pre-lubed with corbin swage lube(won't detonate). 
I use these slugs in my air venturi Avenger and Avenge-x at around 900 fps. (I've used them also in Daisy Powerline 822)Perfect for pesting and hunting, expands very well with the deep hollow tip.
