Christmas is past, New Year’s has come and gone so now what is there is look forward to… Spring? Could it be brass prep for the upcoming season? Probably not you say.
Match season is almost upon me and typically I have left detailing my brass for a “better time.” Actually there is no “better time.” The time to detail brass is when you have time and are in the mood, but it has to be done so you might just as well get started. I have discovered some shortcuts to help boost production and I’d like to pass one along.
One of those shortcuts involves stubborn carbon deposits on the case necks.
Recently I was cleaning some 6×47 cases in a Lyman vibratory tumbler using nutshell media. After a couple of hours I checked on the cases and they were nice and shiny BUT I still had some carbon on the necks.
There just happened to be a bottle of Bore Tech C4 Carbon Remover nearby. Being familiar with how well this product works in a barrel I wondered why it wouldn’t work just as well on these unsightly carbon stains on my precious Lapua cases. After reading the label carefully I knew there was no brass killing ammonia present so I wet a shotgun patch with a small amount of C4 and wiped a case neck with it and the carbon disappeared. It was so effortless I wasn’t positive there was any carbon present. Even though I knew there was carbon on that first case I purposely picked one I was certain had major carbon stains.
Not only did light finger pressure remove the carbon but the anneal marks as well. My case necks are now carbon free, clean and polished. Carbon removal is no longer the chore it used to be.
I have a couple of other ideas to try out that might streamline this even more but I need another month or so to report my findings. Stay tuned and we’ll see where this goes.
