You can very easily see the difference between a piece of Grendel brass fired using a chamber cut for the .125 bolt but using a .136 bolt. In other words, excessive headspace. The brass will be ballooned out and the shoulder is quite rounded. You can put the brass next to a sized piece of brass or factory load and can see the difference without any problems. It is very apparent without using comparitors or bent paper clips.
