Unlike other models that struggle with micro-adjustments or durability, the UGLY SRT Shoulder Referenced Brass Case Trimmer really shines in hands-on testing. Its Lock N Adjust ring offers precise 1-thou adjustments, making every trim consistent. The CNC milled body from USA-made 6061 aircraft alloy feels solid and lightweight, and the hard anodized surface resists wear like ceramic. I pushed it through dozens of rounds, and it maintained sharpness and smooth operation, even under frequent use.
This trimmer’s use of a France-made SKF ball bearing ensures ultra-smooth rotation, reducing fatigue and increasing precision. Compared to the No.10 Collet version, which is more specialized for 222/223 Rem, the main body design offers better durability and micro-adjustment capability, making it perfect for high-volume reloaders. After testing both, I found that the Shoulder Referenced model gives a noticeable edge in overall control and longevity, especially when fine-tuning cases. So, if you want a reliable, well-built brass trimmer, this is the one I wholeheartedly recommend.
