I started with the attitude that the gun seemed to be a gimmic but if the website is accurate, they actually developed a decent round.
If the slug is actually staying supersonic beyond 200 yds then it can do what a 3" Brenneke does at 100 and do it accurately.
As far as skybusting and the like, there have always been those who have had limitations in the ethics department and that was regardless of skill or what gun you put in their hands. (The Ithaca mag 10 has been around for a long time)
I forsee a double in 3 1/2. Could be interesting.
