I do not own one and have never even seen one, but the paper ballistics are quite appealing to me, especially since factory jacketed bullet ballistics {of the old 400/2150 load} could pretty easily be duplicated by cast bullets which would make this thing a dandy for cheap plinking with ammo that would probably maintain same POI to the fatory loads.

I do notice, however, not many jacketed component bullets available, in fact, nothing like that available for the .416's.
