Vacuum powered bullet holder system for ballistic analysis

A bullet holder system to be used in forensic investigations of ballistic marks on a fired bullet, wherein the bullet holder system consists of:

• a head configured to transfer an air vacuum power to the bullet;
• a vacuum bushing and a vacuum hole inside of said vacuum bushing, wherein the head is placed inside the vacuum hole and the vacuum hole is fluidly connected to the head;
• a pneumatic hose connection hermetically sealed to the vacuum bushing and configured to transfer the air vacuum power from an external source;
• wherein, the vacuum bushing has a plurality of sealing elements to hold the head, which allow a negligible amount of air leakage which does not affect a hold operation;
• and
• a roll motor assembly configured to roll the bullet by 360 degrees and a gap for a shaft of the roll motor assembly, wherein the roller motor assembly is disposed in a roller motor housing;
• wherein, an inner structure of the head transferring the vacuum power to the bullet has a conic shaped shrinking geometry and is coated with a semi soft mould;
• wherein the bullet has a conical front end located inside the conic shaped shrinking geometry of the head;
• and
• wherein the roller motor housing and the vacuum bushing are stationary seated on a base.
