Am I correct to guess you are using Unique or something faster? Too fast (not necessarliy too much) and the case will expand and grab the chamber wall before bullet separation/case setback happens. You wind up with pushed out primers. Too fast and too much and you may see the pushed out primer flattened and excessive case stretching.

Straight wall cartridges in a revolver(more headspace) are more prone to this.
