I’ve got some 1x fired brass that ranges in length. The measurement from the shortest to the longest case is .005”. Would you trim or leave it?

If they exceed the "trim to length" in your manual, yes. If you have a carbon ring build up, that variation could give you some pressure problems too.
Consistent brass prep is one of the things you can control.
Deburr inside and outside of cases mouths after and hit it with steel wool to polish the chamfers.

How close are these measurements to the "trim to length" for your cartridge ?

Edit - Bob Wright asked first.

6.5 PRC cartridge. Length ranges are well within case dimensions
