[QUOTE="Shawn Carlock, post: 259838, member: 4"] If you place the forward cradle on the neck it will not allow you to read the neck runout into the total runout of the bullet. The Sinclair picture posted above is the correct way to read total bullet/case runout. If you place the cradle on the neck and the indicator on the bullet all you are reading is bullet/neck runout. If you have no neck runout this is fine. The important part is to insure the bullet is going straight down the bore, bullet/neck runout is only part of the the total bullet case runout. Since we are using the chamber to hold the case/bullet square with the bore we need two things: 1. A square to the bore chamber. 2. The bullet square in the case. If you measure bullet runout against the neck and the neck is offset or crooked with the bullet to neck runout at .000" you will get readings of .000 If the neck is offset or crooked .003" and you test runout with the cradle under the neck you will still get .000" If you test as pictured above you will get the proper runout of .003". The bullet has to spin in the center of the case, just because it spins in the center of the neck may not mean it is straight with the axis of the bore. [/QUOTE]
