I'll tell you once again...
before you go out and spend $100 on a new trimmer, replace the handle with a cap screw and try the drill thing (mine's on a RCBS)
I had 300 .357 Herrett cases to trim that are made from .30-30's. Had to take 2/10th's off each one. I wasted money on special made "trim to length" dies (what a joke).
I can cut the .200 off in maybe 15 seconds apiece. Once the stop collar is set, each case is exactly the right length.
Push the spring loaded handle and put in a case, put the drill against the little bolt and trim until you stop at the collar, and put in a new case. Takes about as long to do as it takes to read this.
I've got an extra Lyman out here and I think it's the same as the RCBS, IIRC
