[QUOTE="Predator 22, post: 1250553, member: 79364"] Mikecr is correct. A false shoulder is usually the same thickness as the neck. Tapering slightly towards the neck shoulder junction. When I form 22-250 ackley I run standard brass over a 6mm expander then back down part way to 22 caliber, This is a false shoulder. When done fireforming that false shoulder is usually made into shoulder and any of it that is forward is easily fl sized. Now a donut is brass that is actually thicker than the rest of the neck right at the neck shoulder junction. Making Sherman Short Mag brass creates a very pronounced donut. I will try to get some pictures of it when I get home next weekend. [/QUOTE]
