This method was soon replaced by "crushers," developed by Nobel in Europe at about the same time. Crushers are copper or lead cylinders deformed by the piston. The deformed length of the crusher is measured and compared to a table supplied by their maker with each lot of crushers. The pressure is read directly from this table.

To measure pressure, a copper crusher cylinder is compressed by a piston fitted to a piston hole into the chamber of the test barrel. Pressure generated by the burning propellant acts on the base of the piston, forcing the piston to move, thereby permanently compressing the copper cylinder.
