No I mean they rattle inside the can. But it's usually only 2 or 3 in it.
Where there is your problem, you need way more calls than you can use in there to make it not rattle.

I have never had that problem. I usually have to throw one away in order to put one in it. Dang beginners! Drill holes in it so they can air out and throw a couple cotton balls in there for buffer to keep them from rattling.
