Re: Case cleaning - vibratory, or ultrasonic?

Okay, I know I'm gonna get flame for this but wouldn't the carbon deposits be uneven from brass to brass causing different bullet release rates and less precision? I'm looking for a brass cleaning system too for precision loads otherwise I wouldn't have bothered ya with the question. </div></div>
No Flaming What So Ever
I belong a shooting club in Denton Texas, NTSA(North Texas Shooters Association) we have Trap, Skeet, 5 Stand, Pistol, Rifle ranges, all the 100/200 yard BR matches are held at my club, I watched the BR boys reload there cases, clean by hand on the outside with a Krazy Klothe, 0000 Steel Wool, or any thing else to remove the burnt gun powder from the outside, necks are brushed out leaving a dark grey(carbon) residue, primer pockets brushed cleaned, resized with a custom made FL/Bump die(as near as I can tell its a Hybird that sizes the neck very little, sizes the body slightly, and bumps the shoulder .0005-.001), most throw there charges, but the really good shooters pre load charges in tiny vials, each charge is weighed on a GD-503 or better, charge and seat bullets. What I figured out is these guys shoot little bitty groups all day long with cases that never get cleaned to even close as the level of Walnut media does, let alone SS media, so I just used 0000 steel wool to clean the outside of fifty cases, brushed my necks out, brushed my pockets cleaned, I already use a highly accurate scale to dispense my charges, anneal every 3-5 firings( really when I feel like it) and I discovered my SD/ES went down, my groups shrank, and fliers all but disappeared, WOW dirty brass(or at least brass that's nowhere as clean as SS media cleaned brass) shoots better. My therory is the carbon acts as barrier between the inside of the neck and the copper jacket, no cold welding, and when fired those two aid in the release of the bullet. Cleaning cases by hand sucks, all the washing and drying of either US or SS Media sucks, fire up the Lyman vibration cleaner with Walnut media treated with NuFinish car wax is the least amount of work, cleans what needs to be cleaned, and produces shiny brass, or brass clean enough not to damage the dies, and IMHO is more accurate, as for unevenness I don't know, my runout is very low, my spreads are single digit, and after 4000 rounds my 260 still bug holes. </div></div>
Thanks for sharing this Cobra. You are a gentleman and a scholar and I'm gonna try your method too. All I had anyway was a SWAG that cleaner was better both inside and out cuz I've never reloaded anything but shotgun shells so far...also your gonna love this. I was at the Mecum Auction last weekend here in FL and there was an old boy there from Kentuky who had an original Shelby Cobra 428 roadster, which was by far the most expensive car there! The bid went to $650K then stalled so he took it back home with him. He told me he wanted 7 figures for it or he wouldn't sell it before crossing the block.
