So, I've been using a Lyman Universal Case Trimmer to trim my brass and Im thinking about an upgrade. The Lyman is an older trimmer bought back in the 80s when my pops first started reloading. Im not sure if its due to age, or just characteristics of the product, but when Im trimming I notice sometimes the case moves around when it's supposed to be locked down, the lathe portion has a wobble, and it trims unevenly. It does the job, but there's a lot of stuff moving and wiggling. So, Ive been thinking about one of the electric case prep centers or one that chucks up in a drill. I was just looking for some opinions/recommendations on whats out there and what you good folks are using? Ones Ive looked at are the worlds finest case trimmer, trim-it, and the frankford arsenal case prep center with the electric trimmer. Just didn't know if any of these are worth a damn and accurate/consistent.
