I trim them to the factory standard length as specified by the manufacturer.

I simply refer to the recommended trim length listed in the reloading manual I am using.

Any consistent length will work as long as it does not excede the max.
length for the cartridge in question. Most reloading manuals recommend
a trim length of -0.010" from the max. case length. For hunting and
competitive loads I trim to this specification, Max. -0.010". For plinking, fire
forming, fouling rounds, rough sighting in rounds and general f-ing around
stuff anything under max case length is loaded.

If a case is too long you can pinch the bullet in the case mouth due to the
chamber cone transition to the rifling of the barrel. And that is very bad as
the chamber pressures can spike very high and cause rupturing of the
chamber or barrel, both very bad situations.
