Triming 223 to make 300W (cheating ?)

[Casey]

I took a simple drill press vise and with the jaws tight drilled a hole in the middle just the right size to hold the case tight. Spinning a 1/2 end-mill at 2000 rpm eats them right up. Repeatability is within .003" and it cuts faster than the mill in the video. I do run them through my wilson trimmer after the final sizing to make sure everything is square. I don't make a lot of brass but I sized, cut, and trimmed 100 cases in a few hours, good enough for me.
