For years I trimmed brass with either Lee hand trimmers or a Forster case trimmer. Those products both worked but were time consuming and could really wear out the fingers if trimming a lot of brass. I recently bought a Lyman Case Trim Xpress and this thing is amazing. It's easily one of the best reloading tools I've ever bought. I can trim 50 pieces of brass in about 5 minutes and not have any sore fingers when I'm done haha. It's very easy to use and setup and comes with many bushing for most every common cartridge. I highly recommend checking this trimmer out if you're wanting to upgrade or looking into one. The price is really good for what it is and it's much more affordable than some of the other powered case trimmers.
