I jumped on this bandwagon several years ago. Used tumblers, and still do to polish, but after researching several I opted for the Lyman. Just after doing so I discovered 3 buckets, 41/2 gallon full of handgun brass I had stashed and over looked when I fell heir to a supply which of course finally petered out. In two weeks I CLEANED, after depriming, what would have taken me at least six months just using tumblers. This stuff was REALLY dirty. I came to the conclusion that the reports I had read, and there were only a couple, that said they didn't work, was posted by those that didn't follow the simple instructions. All that brass got cleaned up, and these days I only have to clean what centerfire handgun brass that I shoot.
There has been a LOT of brass through this thing and last week or so I cleaned up about 10,000 pcs of nickel 9mm that I had boxed up waiting for another day. Primers removed it did a super job on this stuff that had been sitting for a long time. Looks like almost new and hasn't even seen the polisher yet.
I only polish when I am ready to load it.
As for the mixture, I use the Lyman mixture and add a package of orange 'kool-aid' the old non sugar stuff. So, in conclusion, I wish I would of had one years before I did. :mrgreen:
Those that claim to have problems of corn-cob, etc. clogging primer pockets,?? I always wait until AFTER I clean and do a first polish, to resize my brass. Just my way. And Yes, I am retired and have such time, and, I always work ahead of myself. :mrgreen:
