I bought a couple of boxes at Dicks sporting goods and I want to say that I paid about a 25 bucks a box. I cuta shell open with my pocket knife and was suprised at the two different types of shot it had. Some looked like minature flying saucers that looked like they could really cut a swath. I also read that they have some sort of flight controlled wad that seemed to be constructed out of a much harder plastic than most wads I have seen. These are just some of my observations. They seemed to kill the ducks just as dead as the cheap XPERT high velocity loads.
