The rifle being loaded for is a milsurp .303, so the extremes of benchrest accuracy are not being sought.
One school of thought I'm aware of says "Look up the trim-to length (e.g. 2.212" for the aforementioned .303 British) and set your trimmer to that." Cases which might be shorter for whatever reason thereby get nothing. I'm assuming the Lee hand-held trimmer pilot is set to cut to this length, or something acceptably close to it.
Within this, there are those who will trim every case to the trim-to length and those who will leave cases that aren't over length well enough alone.
The second says "Find the shortest case in the batch with your calipers, set a case trimmer to that and trim everything down uniform" - I think this is a benchrest technique.
I have both the Lee hand system and a Lyman case trimmer, though it's been so long since I used the latter that I can't remember what it's set to. I feel the best solution is probably just to trim one case in the Lee, use it to set the Lyman, and go to town on all of them - if anything's shorter, what the hell, it's not as if I'm crimping in any case. Then a quick chamfer and deburr and it's done for a while.
Advice? What do others here do?
Cases are currently being neck-sized only FWIW. Previously in the Lee Loader (whackamole); now a Collet die has been obtained and will be tried out presently.
