As far as affordable vibrating tumblers go, this one works great for cleaning brass cases. With crushed walnut media, you get a lot of dust. Walnut media cleans well but the brass doesn't come out shiny. There's almost no dust with crushed corn cob media and it cleans well too and the brass comes out shiny. If you want it polished, add some polish. The cases come out clean using either dry media. If you remove primers prior to cleaning, the primer holes won't be as clean as using wet media with steel pins and little pieces of the dry media get stuck in the primer pocket and flash holes. They are easily removed with a small pin punch or compressed air.
I've been hand loading ammo for 42 years and I've always had an up to date Lyman manual on my bench. Why? Lyman included loads for cast lead bullets where many other manuals do not. The last several Lymans, including this one, have been printed in the large 8 1/2 x 11 page. Orange highlights the max loads in every caliber so there's little chance of misreading or misinterpreting load data.
A favorite rifle caliber of mine to reload for, .308 Winchester, shows 12 jacketed bullets and 7 cast lead bullet loads. In .45 Auto using a 200 gr cast SWC, the manual lists 20 separate powder loads.
Page 12 through page 85 walks the new reloaded through the entire process, step by, step using large color photos and very specific information. I always read through these chapters as there's usually a pointer or two that I pick up on that I haven't been aware of previously.
New calibers listed included the .300 Blackout, 6.5 x 284 Norma, and the 6.5 Grendel, among others.
