Did you neck-turn your cases (for constant case wall thickness) and maybe have case walls that are now well under standard thickness? Three whacks doesn't sound like excess bullet pull.
Measure the case neck ID after sizing with both mandrels. The case neck ID should be 0.001-0.002" under bullet diameter. Measure the case neck ID and bullet OD after pulling a bullet to determine if you might actually have excess neck sizing.
