In a recent thread, someone mentioned a 3 way trimmer that is purpose built for each caliber. Used in a drill or drill press. I though I bookmarked the website, but obviously had a brain fade and can't find it now. I can tell you what it's not. Trim-It II WFT from Little Crow Giraud Wilson RCBS Redding It is only sold on the owners website, no retailer or ebay. I have done searches but still no luck.
