Unless you're loading for high dollar compition there's no advantage to having clean primer pockets.
Now that the weather has cooled off and I feel like going to the range again, I really can't see myself cleaning a few thousand primer pockets that I shot last week, and I'm retired with the time to do it. Just ain't gonna happen.
Mr. Kimber nor Mr. Carbine, nor Mr Winny 94 will never know the difference.
Folks get to wrapped up in things that mean little. At least thats my opinion, which I realize means little as I've learned as I got older.
