If you bite the bullet and buy an RCBS Trim-Pro, life will be good. Absolutely get the 3 way cutter which deburs inside and out. I trimmed a little over 1000 223 with a Lee zip trip once. What a PITB that was. To me the power unit was worth it just for the 223s but the bonus is that it does all calibers. I should have mounted a cookie sheet below it to catch the oil runoff.
