I just got my new LE Wilson case trimmer a few days ago. I have had a Hornady trimmer since I started reloading but have always had problems with it making smooth, square cuts. I have also used a friends RCBS and Lyman, these seemed to be decent trimmers. The Wilson trimmer blows them all away. I just got finished trimming a batch of 300 winmag, and they are amazingly consistent. I know there are quite a few guys on here that use this trimmer, but for everyone else, you need to try one of these.
