The bullet has a hard sub-caliber core contained within an outer sleeve and separated from it by a polyethylene layer. If the bullet strikes an unarmored target, it holds together to produce a wide wound channel.
The bullet's construction, consisting of a solid core encased in a protective outer layer, separates the core from the outer layer by a polyethylene barrier, and its ability to create a wide wound channel upon impact with an unarmored target are all key aspects of its design.
