Reloading .223 or 5.56? Swaging with the Dillon Super Swage 600

I have noticed some 5.56 brass and even .223 brass may have stubborn primer pockets making reloading difficult. While a crimp remover is important, swaging the primer pocket makes tremendous difference too. Since I started swage this brass the problems have gone away.
