I bought a lyman xpress trimmer just a short while back. It works great if you are only taking a bit off, I had a bunch of 30-06 I converted to 7mm x56 and I only roughly sawed off the head with the HF saw, and some cases were 30 to 50 thousandths too long. Those tend to grab as you are really taking a lot off. Those about 5 to 10 thousandths long work well and pretty easy on your fingers. I've the lee zip for 300 BO and 22tcm and it works pretty well with the small drill. No hand holding. For those who have issues with finger pressure, i.e. arthritis, this is a better option.
