Since moving to the Dillon 550 from hand priming / single stage setup, I've noticed the variances in primer pockets when using range brass. I'm loading 9mm.
Most seat smoothly but on some case types the primer pocket deforms the primer and a lot of effort is required to seat the primers.
In addition to the worry of primers detonating it slows the whole process.
So....do you guys swage primer pockets or just sort cases according to head stamp?
