Cryogenic physics has discovered that strange things happen when matter is taken to temperatures of -300° F; gases become liquids, ceramics become conductors of electricity and steel is changed at the molecular level.
When a Benelli barrel is cryogenically frozen, all of the stresses caused by hammer forging are relieved and the surface of the bore takes on a more even-grained, slicker surface that offers less resistance to wads and shot charges. With a smoother and more uniform surface, Benelli’s Cryogenically Treated Barrels not only pattern better, they stay cleaner.
Crio® Chokes are the second part of the Benelli Crio® System. Extra long choke tubes, with a more gradual constriction, coupled with the slick surface caused by the Crio® treatment puts more pellets on target. The Benelli Crio® System improves patterns by as much as 13.2% and yields denser, more uniform shot patterns.
Benelli’s Crio® System Technology
Better Shot Pattern
With high speed cameras Benelli engineers caught test patterns in flight. Cryogenically Treated Barrels and chokes threw patterns with substantially denser and more uniform shot patterns than common shotgun barrels.
Why Freeze a Barrel?
Hammer-forging induces stresses in the barrel steel caused by an uneven grain structure (left). Freezing the barrel to -300° F changes the steel at the molecular level, leaving a more even grain structure. The result? The barrel flexes more predictably and has a smoother bore surface that resists fouling.
Pattern Comparison
When compared to the competition, the new Cryogenically Treated Barrel puts 13.2% more pellets in a 30” circle. That’s bird-busting power you’ll see in the field! This sort of pattern performance once required special barrels and aftermarket choke tubes. With the Super Black Eagle II, you get it right out of the box!
Crio® Choke System
The specially designed longer choke tubes of the Crio® Choke system allows for more gradual constriction of the shot charge, which reduces pellet deformation. Frozen to -300° F, Crio® Chokes have a more evenly grained and slicker surface that provides less resistance to the shot charge as it passes through. When coupled with a Cryogenically Treated Barrel, the result is as much as 13.2% more pellets on target.
