OCHP: With a production begun in 1526, now accounting for more than 500,000 barrels a year, Beretta is a world leader in technological research applied to ballistics. The Optimabore HP technology, combined with Steelium, provides excellent accuracy and pattern quality with any kind of shots.
Steelium: the production technology of the Beretta barrels, making the special tri-alloy steel become an outstanding ballistic jewel, thanks to a manufacturing process that is just as unique. Gundrilling, cold hammer forging special vacuum relieving give steel the ideal mechanical characteristic for superior ballistic performance.
Steelium Plus: all the benefits of Steelium, plus the tapered internal profile (360mm) for an even smoother pellets dynamics and, ultimately, better patterns and more broken target clays. (available only on 692)
