Working APFSDS for a ½" PVC Air Cannon. Uses a 2.5mm x 50mm nail with a 5mm head. Be careful when shooting, never aim at any living being. Wear eye protection, and stay a safe distance away in case of ricochet. Use with extreme caution. The last image was taken after the use of a 40psi blast. At this strength, safety is crucial.
