i freind of mine used an old clothes dryer.the heat elements had burnt out but it still spun.he sealed up the holes in the drum and added a bunch of media .he would throw in a couple hundred brass at once.i think he said he could do 500 308 sized brass at a time.seemed to work ok,i remember it was noisy as hell,i don't know how long it took to complete a cycle ,but i remember the brass looked nice after.how big is your reloading room??lol.
