Brass prep - 03/01/21 11:55 PM
I had been reading about tumbling brass before decapping. The idea was to prevent the media getting stuck in the primer pocket. This is a small pain but not a huge issue.
So, I figured I would give it a try. The media I use is walnut.
I took 100 of the spent 308 cases, then washed, dried and tumbled. After tumbling, I even took the step to wipe of the media dust off each case and then tapped each case, neck down, to ensure no media was stuck in the case. I then decapped in a decapping die.
Anyone do this?? I won’t do it again. Created a mess in and around my press.
It seems that some media had gotten into the flash hole. The media was jammed into the primer and it also created a bunch of dust and particles in and around the ramrod.
I now have to inspect each case to ensure there is no media still in the cases.
