1. A shaped charge comprising:
a shaped charge case comprising an inner surface and an outer surface, wherein the inner surface defines a hollow interior of the shaped charge case;
an adapter coupled to the inner surface of the shaped charge case, the adapter comprising:
a collar; and
a plurality of members secured to the collar in a spaced apart configuration from each other such that the adapter has a central open area;
an explosive load disposed within the hollow interior atop the adapter, such that the explosive load covers the adapter and is in direct contact with a portion of the inner surface of the shaped charge case; and
a liner disposed adjacent the explosive load, wherein
at least a portion of the adapter displaces some of the explosive load, and
the displaced explosive load is configured to accelerate the liner to produce a perforating jet upon detonation of the shaped charge such that the adapter is configured to produce an atypical perforation hole geometry in a target.
