neck can be ground slightly shorter than shown.
The reason for this is that when you grind the shoulder, the neck then can be set to the proper length by
taking the shoulder back a little at a time.
The shoulder angle is next, and it IS VERY IMPORTANT TO GET RIGHT, as this is where the head
space is taken from on rimless cases.
This can be set from the taper and angle charts. If you fill that you can set it properly from the angle
setting set on the compound of the lathe do so?
Grind now the taper on the body of the case. This is also set from the angle and taper charts. This is
important to have this right so cartridges will fit in other guns of the same caliber. If you are making a
reamer for a belted cartridge, this will have to be ground next.
GRINDING THE CUTTING EDGES
All the edges of the reamer have to be sharpened so the reamer will cut freely. This is the throat (if you
use one) the start of the neck, the shoulder, the body of the case, and the start of the belt (if you are
making a magnum). It is done the same way as shown in the chapter on barrel reamers. After making
one or two reamers, you will understand fully how to do this.
