With all deference to the fellows selling their cannelure machine, I had a job that couldn't be done with a hand cranked device. I ponied up the money for one of Dave Corbin's automated cannelure machines. What a beast. Built like a tank and works perfectly. Below is a short video I just shot. It's much easier to handle the bullets when you aren't holding the camera with the other hand.
The job is to cannelure 50 AE bullets to use with the Desert Eagle. While the round chambers on the case neck, without a significant crimp I always would get some bullets set back upon chambering. With this method, I don't have to crimp as hard and I have not had one move yet.
Since there isn't much written about these machines, I thought I would share. The jackets on those bullets are probably .075" thick, so this is doing quite a bit of work with ease. If you wanted to, you can use multiple wheels and even get a wheel to completed diamond knurl a lead boolit.
