Hi. Is there a dissolving ammo? I've encountered the following: we have a projectile impact on a windscreen of a vehicle. But no traces of the shooters position, and the windscreen wasn't perforated. Thuis would mean the shooter was nearby and shot with a low calibre, or he was very far with special ammunition which didn't pierced the windscreen, and apparently dissapeared. CCTV analysis showed that no shooter was on the nearby rooftops neither. Does anyone knows what could have been used? Thanks a lot.
