When I trim I try for somewhere close to min as a rule. So for 6Arc I'm set at 1.483.
I have multiple barrels which I keep close to each other in spec (I had a couple grendel barrels that stretched way too much so I got rid of them) so I size down 0.005. That covers me for all of them.
You don't want to go out to the 1.500 b/c you need to allow the case to expand out during the firing a bit, then shrink back.
