In there description they talk about using a the trocar point since they penetrate the dermis so efficiently , then they state that it delivered "increased" kinetic energy??? True a trocar does penetrate flesh effectively which may enhance penetration, but seems to be counter intuitive that this pointed object would deliver more energy than then a large round flat object?? Apparently they have overcome those nasty rules of physics, tissue elasticity, energy transfer. Would I try them, sure if they send them to me for free I would test them, but I would not buy an unproven design @ $50/ 20 rds, when I know the effects of many other fine rounds on the market. Maybe they have developed the mythical 1 shot stop. Be Safe,
