I see what you mean. Well I doubt I shoot that much to need to tumble a lot of brass. Not sure how many say .270 brass will get 15 lbs but guess I can play around with this. So you have the Thumblers Tumbler. Will have to see how much this costs. Do the ones from Harbor Freight work good as well? Reason for asking is because "I want to buy once and cry once" hehe.
