[QUOTE="MagnumManiac, post: 1408308, member: 10755"] I use the exact same method as Bigedp51 does, BUT instead of bushing dies, I use modified FL dies, custom mandrels and body dies. I also run graphite through my necks. I run neck tension from .0015”-.004” depending on barrel. I polish with 1200 grit wet/dry WD40 and spin up the expander rod in the lathe or drill press. I mic every couple of minutes until I get the size I want. I was sick of donuts, so moved away from bushings. My necks don’t get moved more than .003” in any operation, all of my dies have had the necks honed and the expanders polished to the EXACT size I require. Some of my ammo/barrels were once tight necked, running .0015”-.002” clearance, I found this too tight and I get better results with .003” and one barrel prefers .004” neck clearance. I still skim turn my necks, just for consistent wall thickness. Cheers. :) [/QUOTE]
