I've not had pistol brass grow that i remember. Generally, bottleneck rifle cases grow as they are dragged over the expander ball. Straight wall pistol brass doesnt get dragged over an expander ball, it is pushed into an expander. If anything, pistol brass tends to shorten over time, or at least stretching is held to a minimun. YMMV
