Resized and trimmed 50 300BLK cases chopped down from .223 brass. The HF saw and jig don't make a super-clean cut, but good enough. I'm using the Lee trimmer after resizing which I love for the quickness, and the fact I can chamfer and deburr with the case still on the cordless drill.
Some have complained the Lee trimmer doesn't trim to the correct length. What I found is you have to set it right the first time, which the instructions never mention, and it does a good job of providing a consistent trim. If you assemble the two pieces of the cutter as far as the cutter will go in, you'll be trimming way too short, which I imagine is the source of some of the complaints I've read about it.
My L.E. Wilson trimmer is great (once I replaced the cutter), but slow.
I have 500 Starline 300BLK cases on the way, presumably in one of the years in the not too distant future.
