Re: Neck prep question
I like the carbon layer in my necks, as it provides for consistent seating forces and there is no downside to it.
When I get back from the range, I hand deprime cases, scrape the carbon out of pockets with a twist of a pocket tool, & wipe the neck outsides with a rag of 'carbon killer'.
The cases are dropped into a vibratory cleaner with a semi-coarse media & run for an hour.
Then I pour the cases into a media sieve and knock any granules out of flash holes with the handle of a small screwdriver.
Now they're ready for sizing/reloading.
