I love these quick cut dies! Also have and use them on my .380 and .223/5.56 cases. Saves so much time trimming suitcases, easy to set up and use, and they're inexpensive! Just a word of warning, if you're interested in this, make sure you have or buy a Lee Deluxe Quick Trim Pen (sold separately). I didn't have this problem; but I saw others who didn't understand.
