I think it is innovative and interesting. The web page contains much information concerning interior and terminal ballistics as well as mentioning flight charecteristics. However it would be helpful to know the muzzle velocity, ( it might be there, but I did not see it for any of the slugs) and to know the actual drops and wind drift. I highly doubt a number for ballistic coefficient would be useful and the bullet shape and material would probably not match up well with any ballistic program I am aware of. I do not see all that as a negative though, just an observation. One could easily figure out the velocity and drops rather easily with a little range work. I would think that the wind drift on these would be rather substantial just like it is on most other slugs, maybe even more so, but that is just a guess. They would have to be accurate to get a good idea of their wind drift characteristics as this is usually a little more difficult to figure out then an average for drop rate.
Are these even available in the USA? Also I wonder how the costs compare to other sabot slugs on the market.
