I love seeing all that brass and it is very pretty!!! I like using my concrete mixer for a tumbler as it will do 2500 to 3000 brass at a time and it comes out looking this way!!! I only have to tumble for three to four hours once every couple of months and it works great. I got tired of having that little thingy going buzzzzzzzzzzz all the time!! If you get into production at a larger scale the concrete mixer is the only way to go!! Keep up the good work and shine those cases!
