How good are the neck walls?
I have no idea. I don't have the equipment to measure neck walls. I don't have any tight custom chambers, nor any that require neck turning, so I have never concerned myself with neck wall thickness.
My prep for new brass consists of a pass over the expander ball in the sizing die to make sure the case mouth is round. Then I use a flash hole uniformer, inside chamfer, and outside deburring on the RCBS Trim Mate case prep center. Done.
I'm not sure what that makes me, in the grand scheme of the handloading hierarchy. Lazy, perhaps?
Brass prep is easily my least favorite reloading chore.
