i just ordered mine from cheaper than dirt. i bought an extra box or two so i could fire them and see what kind of reaction my 12 ga had to them. they hit pretty hard at 40 feet or so and yes i am backing them up with real rounds.

they come out of the shotgun like a 223 round maybe even easier.

if you or whatever i am shooting at are still wanting to fight after the first two bags then the next one is real.

they claim to be able to break ribs at 30 feet.
