223 Rem. Finding the distance from case head to rifling

This may result in a stuck dummy round or broke bolt. I took 2 scrap brass, placed a Sierra 53 gr flat base bullet just lightly into the case neck. Locked the bolt down, pushed the bullet into the case. Taking a measurement from case head to bullet face is 1.965" Rifle Savage Axis 223.

This measurement can be used to gauge throat erosion after firing many rounds. The bullet is jammed into the rifling, so this measurement is different then the normal method/tool used to find head to bullet ogive length.
