this. I don't own a quick-trim, but I watched my uncle throw one across his garage in anger multiple times
their drill mounter lock-stud and cutter is actually pretty good as long as you know its limitations (it's not adjustable, trims to the length of the caliber-specific guide, which is always a hair under the max case length.) I'd have to check, but I think it trims my .38 spl and .223 to about .007-.012 short of max case length. For my applications, this is totally acceptable.
