How do you trim your cases? We use a variety of tools, including power case trimmers. But our go-to trimmer for Benchrest-type cartridges is the L.E. Wilson Trimmer unit, now available in a handsome and durable stainless assembly. This thing is slick. It trims very precisely with the use of Wilson case holders combined with a micrometer-type stop for length control. As sold complete with micrometer, quick clamp, and metal stand, this Wilson Stainless Trimmer is $154.95 at Creedmoor Sports. We think that’s a fair price for a unit that can last a lifetime, trimming many thousands of cases.

In this video, Bill Gravatt of Creedmoor Sports demonstrates the Stainless Wilson trimmer with micrometer length control. Gravatt offers helpful operational tips to improve trimming efficiency, so this video is worth watching even if you’ve used a Wilson trimmer before:

Tips for Trimming with Wilson SS Micrometer Trimmer:

1. After inserting brass in the case holder, tap the case lightly to ensure it seats fully.

2. When starting your case-trimming session, do one or two test cases to check cut length. Adjust length with micrometer, then test length again. If “good to go”, set length stop. NOTE: Release the Stop Screw to make major adjustments. Use the Micrometer to make fine adjustments, in .001″ increments.

3. After trimming operations, be sure to chamfer case mouth after cutting to remove burrs. NOTE: After you have made the chamfer, we recommend gently spinning the chamfer tool backwards a couple times in the case neck. This will burnish/smooth the newly-cut champing, which helps with bullet seating.
