The Late Boy Scout conducts an experiment on what kind of wound cavity Colt’s Solid Copper Hollow Point (SCHP) bullets would create, using clay as his testing material. He says the SCHP bullets are affordable, and he’s gotten some velocity and reliability out of them. The point of this experiment is twofold: he wants to capture some expanded bullets and see how they look, and he also wants to capture a cavity expansion.

To do all that, he’s set up a block of pottery clay on a table, in front of two water jugs and a piece of wood. The clay measured 4 inches high by 5.5 inches wide by 13 inches deep. He fired a few rounds of each kind: .380 with a Ruger LCP, 9mm with a Canik TP9, .40 with a Glock 23, .45 with a Tisas 1911.

With the .380, he got a cavity width of 6 inches and a penetration that was 9 inches deep when he cut the clay block in half – the expansion looked pretty perfect. With the 9mm, the bullet blew a hole right through the clay and through the two water jugs. The petals on the round actually got lost.

With the .40, the front end of the clay block crumpled through, and there was no penetration until the water jugs. When he cut the clay open, the cavity width measured 8.5 inches and penetration went up to 11.75 inches. The pattern of the petals opening could be seen too, and the bullet had a near-perfect expansion with all the petals intact.

Using the .45 bullets, the Tisas 1911 makes quite a shot, nearly smashing the clay block and hurling bits off it. It had the largest transference of energy, but the water jugs remained intact. When he cut the clay open, the bullet was lodged all the way on the other end of the block, and showed perfect petals. The cavity measured 12.5 inches and penetration went 13 inches deep.
