I have a Lee Quick Trim Deluxe and two dies (.223 & .308) for sale. They allow you to trim on your press. Have used the .223 for about 5 cases when I brought it to try it, since then it's sat in my reloading box as I've only been processing about 20 cases at a time so haven't found the need for it. Trimmer automatically trims and chamfers (in and out) all in one go and can be adjusted for trim length by up to 10 thou.
The trimmer tool and .223 die has done 5 cases so is effectively brand new (just for some swarf in it that I will clean out), the .308 die has never been used.
Lee Quick Trim Deluxe Tool £15
