I learned long ago not to make a blanket statement about anything. I use the Lee Factory Crimping die as a crimping die. I am looking for the extra bit of pressure to build in the case before the bullet in propelled down the barrel toward the target. I can't talk about swaging bullets as I don't cast bullets. I can say I do adjust my dies to archive the best results I can from my components and weapon. My reloading equipment is all Lee it works well for me, For each caliber I load my die are set in their own turret so setting up to reload is simple. But I do check ajustment often enough just to make sure things are as they should. Like everyone else I am looking for the best results for my reloads I can archive. Just my opinion,
