Clinker Reduction Frangible 12 Gauge shotgun ammunition, ~1650 fps, 2-3/4 sintered copper powder slug. Intended for industrial use, however this is a slightly faster version of the Engel Ballistic Research Entry slug, and can be used as a primary self defense round indoors, or as a door breaching round.

This is a 'once surface' round: It will dump all of it's energy on the first surface it hits, with devastating results. The copper breaks down into a very high density fluid powder and will find every crack and weakness to flow into at high velocity. The effects on fluid filled targets is explosive. It is much safer than any conventional lead or copper slug in that it is much less lethal after penetrating drywall and similar materials: the copper is a talcum powder fine dust after the first surface it hits.

Hot coal clinkers are strong in compression, but weak is shear, this high density fluid will find the voids and pores and fill them with high momentum copper, rather than just crushing them shut. In addition the copper power will react with the clinker, causing a immediate chemical reaction that will weaken the clinker.

Two applications, take your pick.
