I installed Forster expander and spindle assemblies on all my RCBS dies without problem.

Below on the left the standard RCBS expander raised as high as it will go. On the right the replacement Forster .223 expander for the RCBS die.

For those of you not familiar with the high mounted floating Forster expander it greatly reduces neck runout. The neck of the case is held and centered in the neck of the die when the expander enters the case neck. Meaning the expander can not pull the neck off center and induce neck runout.

Below a modified Forster expander and spindle assembly installed on a Redding .243 full length die. A rubber o-ring is installed under the lock ring to allow the expander to float and self center in the case neck.

Below images of the Forster benchrest full length die.
