Enhanced Castable Frangible Breaching Round

A method comprising:

• casting a projectile from a castable eutectic mixture in its melted form, wherein the castable eutectic mixture comprises at least bismuth, tin, and lead, wherein the mass percentage of bismuth is between 50-100%, tin is between 0-50%, and lead is 0-25%;
• and
• cooling the projectile, wherein the projectile is configured to break into a plurality of fragments upon impact with a target;
• providing, in the projectile, a cavity disposed between a proximal end and a distal end of the projectile;
• forming a pellet of reactive material, wherein forming the pellet of reactive material comprises pressing together a blend of reactive material, the blend of reactive material comprising at least one oxidizer and at least one fuel to form the pellet, the at least one oxidizer comprising a plurality of oxidizer granules ranging in size between 40-400 mesh, the at least one fuel comprising a plurality of fuel granules, ranging in size between 40-400 mesh;
• filling the cavity of the projectile with the pellet of reactive material;
• and
• sealing the cavity.
