We were testing new bolt designs including a cup faced design. The intention was to make it gentler on the paint, but concepts don't always work out as you want...
It turns out that the dimensions we were using were actually "shovelling" up the ball and catching it against the top of the breech as it was fed into the barrel. It led to above normal ball breakage as can be seen in this video.
