I have found I'm becoming increasingly obsessive about cases, both in terms of uniformity and shine (
). In my defence, I have a house full of teenagers, so spending as much time as possible locked in my reloading hut is an antidote to a world of 'Whatever!', 'That is like SO unfair!' and all night Call of Duty gaming sessions undertaken by spotty 15 year old geeks...
I tumble all of my brass, having deprimed without resizing, with non-ammonia polish soaked in the media. I re-size the necks with a Redding neck die offering .002" neck tension and bump the shoulders back by around .003-5" with a Redding shoulder / bump die, then I trim it with a Wilson trimmer (I have case holders for fired and unfired brass), chamfer it at 30 degrees and deburr the outside of the neck. I also ream & clean the primer pocket as well as deburring the flash-hole. After seating the bullet by half pressing, turning through 180 degrees and fully seating, I check and adjust run out on a Forster Co-Ax case jig. I've recently acquired a Sinclair neck turner, so I'll be experimenting with that to see if I can improve on any run-out variations, although the Redding dies are very good.
Tragically, I also tend to polish any lube or finger marks off the finished round with 0000 wire wool, using an old Lee Zip Trim device (although this is usually No.2 son's job).
Result: Shiny, shiny rounds. I have no idea if any of the case prep' makes for more accurate rounds but the fact they are as uniform (and shiny) as I can make them keeps me happy and limits the amount of time I have to shout at the children
Adam.
