It is true some shells had a slight rattle...I sorted through mine several years back. And got close to 10 shells that rattled out of 8 or 10 boxes...contacted Wincherster and they replaced them.
If I buy any I open the box in the store before I buy them and shake each shell....found a few but not many. Guy at the gun counter is going to think you're nuts....
I've never saw the buffer "go to powder"....I'm betting he's meaning the slight rattle.
I have 8 or 10 boxes of 3.5" 2oz #4s on hand ...I figured when I first saw one with a rattle that it would affect the pattern. So I shot them just to get rid of them and I couldn't see a difference in how they shot.
There is a problem with the shell that bares watching.
