For generations law enforcement officers, military professionals and self defense minded individuals alike have trusted the Fiocchi family to deliver the highest quality ammunition for the most serious of applications, protecting your community and family. These Special Application Breaching rounds are designed to take down the most stubborn doors with a minimal amount of collateral damage on the other side. The lead shot is held in a polymer capsule which breaks apart upon impact. This dumps all of the energy into the target, breaking it down and giving you entry. Use only in shotguns with choke no tighter than modified. Do not use in ported barrels, ported chokes, or backbored barrels. Cylinder choke is preferred.
