The Eroder Shot was modeled and shaded in blender, with texturing in Photoshop.

"The Eroder Shot is a concept shotgun round. Aimed at eliminating airborne targets that employ hive like formations such as swarms of insects and/or drones.
Its patented DUST-CLASS micro pellets ensure all targets within a spread are subject to equal impact, thus eliminating the risk of misses caused by conventional buckshot spread.
The Eroder Shot is also effective as an anti-armor solution, making short work of heavy steel plating and even proves effective at draining energy shields."
