I did a test with an LBT 258-120SP, while shooting a .25BR.
The cavities are unmarked. The bullets were inspected and weighed, and I wrote down the weights. The weights were entered in a statistics program called MiniTab.
In the strictest statistical sense, the program showed the bullets were from one population. When the program graphed the information, there were two bell curves which overlapped.
In a match, I managed to make it look like these bullets came from several different moulds of various designs and weights.
