Now that I am reloading for an AR-15 I needed a better way to trim brass I buy to add to my stock. The Lee cutter leaves a LOT to be desired. Picked up one of the Little Crow Gunworks Worlds Finest Trimmer and I am impressed. Accurate clean cuts that will need no extra steps to debur etc. And fast, way faster than the putzy lee trimmer with having to chuck the case in the holder, trim, debur, chamfer...
With the WTF it is chuck it in the drill, grab a case and push it in, wait for it to stop cutting, done. I did 200 cases in an hour and that was with a lot of caliper use on cases that are to short.
