[QUOTE="Mike D Texas, post: 2963479, member: 71221"] If additional seating force is the only "negative" to leaning carbon out of the necks there are multiple ways to overcome this. In my relatively small sampling size (as compared to some here) going up .001" on my mandrel makes a noticeable difference in seating pressure. I also use Neolube as an inside neck lubricant and see consistent seating force (via arbor press and force pack). I even use it when firing new, virgin brass. I've also seen varying opinions on neck interference (some call it neck tension). Some well known shooters run light interference, say .001, some say they run .004-.005 with great results. I personally fall somewhere in the low-middle of those ranges and have consistent results. Since we can't see what ACTUALLY happens inside the chamber when firing a cartridge, I'm not sure we truly know whether interference matters or not. In my mind if everything expands during the firing process, including the neck, I don't know how much it truly affects accuracy/precision/velocity, etc. If it's not dragging out of the case neck due to expansion why would it even matter? When I do want [B][U]clean[/U][/B] brass I wet tumble. Sometimes with and sometimes without pins. the only difference I’ve seen with and without pins is it takes longer without. The brass still gets clean, including primer pockets. The biggest PITA for me when wet cleaning is the pins getting stacked up inside the cases. And drying just adds to the length of the process.
