short answer.
pressure in a void.
longer answer.
the bullet was cooling, the sprue was cooling, there was no alloy transfer from one to the other to make up the take up of alloy.
If I hit you in the base with 15 K PSI your base would pucker too!Not being a bullet forensic technician, what caused that base crater?
I would imagine some base porosity from shrinkage with insufficient sprue. May need to work on that. Pouring longer into each cavity or going back across the cavities after all are filled may help.
Me too. And always in the same voice. Imagine that?I have heard that before. A time or two actually.
