FBI far from experts in shoot outs. Look to the Border Patrol they use their guns more.
IIRC, Border Patrol adopted FBI’s terminal performance criteria a few years ago, after energy-transfer advocate John Jacobs (former INS/BP Firearms chief) and his cadre retired or moved on.
The FBI actually checks their results in ballistic gel against real world results in gun fights.
Prior to adopting 10% type 250A ordnance gelatin as a soft tissue simulant in the late 1980s FBI compared terminal performance results from 200 actual shootings to terminal performance results observed on properly prepared and calibrated ordnance gelatin.
Well over two decades of shooting incident experience by law enforcement agencies across the US has proved the validity of ordnance gelatin and the FBI’s terminal performance criteria.
The hours that went into producing all that data must've been tremendous. Just wish that they would've calibrated the blocks in keeping with the established standard...
Clear Ballistic Synthetic Ballistic Gelatin is not the same as 10% gel prepared to FBI specs. There has been no testing done, that I’m aware of, to correlate it with actual shooting terminal performance data.
Comparison of terminal performance in Clear Ballistic Synthetic Ballistic Gelatin versus properly prepared and calibrated type 250A ordnance gelatin reveals differences:

The origin of ballistic gel testing stems from Duncan MacPherson's work as to modeling wounds.
The late US Army doctor Col. Martin Fackler, when he was assigned to Letterman Army Institute of Research, Combat Casualty Care unit, founded and directed the Wound Ballistics Laboratory. He is responsible for developing the 10% Type 250A ordnance gelatin solution that is the standard today.
Fackler stated – “The field is the ultimate laboratory.” He took actual shooting data and developed a model (properly prepared and calibrated 10% ordnance gelatin at 39-degrees F) that accurately depicted the wounding effects and bullet deformation observed in actual shootings. Fackler was an avid hunter. He also worked closely with law enforcement.
Duncan MacPherson, an engineer, investigated the physics of wound trauma and determined the qualities required of a soft tissue simulant to accurately depict realistic results in typical human soft tissues.
