Ok, so this is the reloading process I HATE most.. I have had and used, the Lee trimmers, a Lyman and a couple RCBS trimmers.. they are all fine if your trimming 20 or 30 cases but if you need to trim 500 these little trimmers just don't cut it..
I shot a lot of 06, 308, 223 and 243 and trimming on these small trimmers was just killing my hands. (old guy arthritis)
So I got the "Worlds Finest Trimmer" from https://www.littlecrowgunworks.com/
I mount mine horizontally in a variable speed drill and just push the cases into the trimmer. I had tried a drill press but that was just too slow. I can trim 400 or more in an hour and it doesn't kill my hands. After trimming all I need to do is debur and i do that using the Hornady battery gizmo..
