[QUOTE="bigedp51, post: 1433284, member: 28965"] The case neck is held and centered in the neck of the die when the Forster expander enters the case neck. Meaning the Forster expander can not pull the case neck off center and induce neck runout. The biggest cause of neck runout is when the expander is locked down off center. And if the case rim has any dings on the inside of the rim it will cause the case to tilt in the shell holder on the down stroke of the ram. And the Forster high mounted floating expander system even prevents the case from tilting in the shell holder. Because the case neck is held and centered in the neck of the die during expanding. Below I replaced all my RCBS expanders with Forster expanders to reduce neck runout. Below on the left a RCBS expander raised as high as it will move, and on the right the replacement Forster high mounted floating expander that fits RCBS dies.

"AND" the Forster expander has far less surface area than the Redding expander. Meaning far less pull on the neck that can move the shoulder forward, no wonder why some people complain about expander drag and effort.
