Chamber pressure Wikipedia
Attaching a strain gauge to the barrel forward of the chamber Copper Crusher Method. Through the mid1960s, the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls. When a cartridge is fired, it compresses the copper slug.
