you can't impress me with a new cartridge because there is nothing new under sun and this one looks a little bit unporportional too.
what is making this more interesting here is the screwed wound cavity in the ballistic gel

it looks like the monolithic bullet flying with 500000 rpm into the target gives this very unusual picture

in the end abnormal and I dare to say you have to pay a price for this. the barrel will be probably worn much quicker than normal but concept looks new and strange enough.
