I started out with a Lyman Universal. That POS wouldn't trim a case mouth square no matter what...
This, plus there's just too much length variation with it as well due to the inconsistency of the chuck unless you re-adjust every case to be sure it's lock up correctly.
I use a Forster, with a drill attached................not super fast, but fast enough for most use unless I have a huge amount of 223 brass, then nothing is really fast enough..
