Range: I estimate effective 20M; max 100M(?) never shot one at anything that far downrange.
The thing is a big solid sintered metal/ceramic cylinder.
You HAVE to have a CYLINDER bore (CYL) on your barrel to use this item... You can have a fancy pants back bored barrel, but it had to start life as a CYL to be safe.
If you fire this slug into a solid object (not a sheetrock wall) at very close range (less than 1M to 2M) you will be engulfed in a cloud of whatever you hit and sintered metal/ceramic. It literally vaporizes whatever the slug hits in way that you have see to belive. There is a considerable amout of backblast so keep mouth closed, eye protection, etc.
At 6-7M the slug will still tear a clean hole through a 5/8 sheetrock panel, at 20M it still goes through, but not by much... Leaves a huge dent and small hole.
I doubt it would go through more than 2 interior walls of common construction. It's too light and it's braking apart and loosing mass fast...
Man the thing is nasty at close range, and it totally vaporizes when its something... I am sure you can imagine what this will do to soft tissue. I would not want to be the Paramedic who gets that call...
