Cleaning media

[Kurt]

I been using the same Dave Maurer's ceramic media now for going on to 20 years but in the smaller .40 cal. cases I always have some I have to dig out and now the .38-50 cases most of them are jammed with the media so I did a search and ordered some Raytech 41222R Microbrite 4mm balls thinking the they should do a good job inside and out as well as not sticking in the case. For some reason I over ordered so I have a bunch for the two tumblers or swap some off.
Have any of you used this ball cleaning media?
I haven't tried any of it yet but I think it should do a fine job.
