Oh good grief don't even get me started on the RIP(off) ammo. I went on an epic rant on here about the time it was released.
Also, great video, thanks for sharing. Even with the plate stopping the round, that clay deformation looks rather painful. Within the limits for "probably non-lethal" but .. ugh. Yeah, you'd sure feel that in the morning!
(At least you'd be feeling something, though!)
Chances of getting shot in the chest from shouting distance by a full size WWII armor piercing round aren't all that good, though. I imagine it fares better against 223, 7.62x39, and 308?
Do you have links to testing on those calibers?
