Maximum Trim Length = Maximum lenght or not???

Been collecting reloading bits and pieces for a while now and finally getting close to actually reloading some rifle cases, but I'm a bit confused by the term "Maximum Trim Length"
Is this the longest the case can be before it has to be trimmed?
Or is it the shortest the case should be trimmed to??
I assume its the former since I think all other case deminsions are maximums... right? [?][?]

I have loaded 45 cases "willy nilly" and while the shot O.K. they shot better after I spent some time trimming and sorting by case head stamp. I know a lot of "Writers" suggest using cases from the same lot number but in reality this is a lot harder for the average shooter to do than you'd think1
If you do any revolver rounds, such as 357 or 44 magnum you'll find accuracy and power in cases all trimed to the same length and sorted by case head stamping.
In this case it provides a much more "repeatable" crimp on the bullet. This equates to consistant bullet pull upon firing which means a more uniform burn which means a smaller deviation in velocity which allows better groups.
Hope this helps.[8D]
if all the cases are the same length it makes them all uniformed when seating and crimping.
things got alot better when i picked up this elect rcbs trim pro with a 3 way cutter
Dillion used to make a motorized brass trimmer for 223 and 308 cases. Had a Bud mount one in his old lyman c press and had at it. Production was fair and it was a whole lot easier on his hands.
