This is the third product I have purchased for trimming cartridges. In my case I only use it for .300 AAC Blackout, mostly for cases I cut from .223 Rem or 5.56 NATO brass. I like the easy setup of the trimmer. Choose the correct shim for the caliber, choose a sleeve that fits snugly in the body but slides in and out easily, and you're ready to trim. However, adjusting the depth is not as easy as promised. Once installed, results will also be affected by how much pressure is used to hold the brass body in place. I've had results that were between 7 and 8 thousandths. I'm trying to do 1,360" but rarely succeed. It's either too long or too short and I haven't found a consistent reason for the difference. Too long I can handle. You can always trim, but try getting an extra 2-3 thousandths is tricky. But too short is just a waste of brass. On a few occasions I've screwed the case down to 1.350". Target, but I'll use it for plinking anyway. Repeatability is clearly the main buy of the Precision Case Trimmer and the main issue I have with this unit. There is no such thing as precision. But quick and easy. I used a Hornady Cam Lock Case trimmer and the world's fastest trimmer, which varies by caliber. Certainly a nod to Hornady as far as accuracy goes, but it also takes a little more effort to get the exquisitely more accurate brass. I probably prefer WFT, but I had some issues with my first case holder. A problem that the manufacturer solved very positively. I bought a Frankford Arsenal trimmer while waiting for my WFT problem to be resolved. But because of the ease of use, Frankford wins Arsenal by a wide margin. If I master the art of setting it and forgetting it. hardly. then I will probably cut all my future cases on this device.
