Does case length matter in reloading?
Accuracy is about consistency/uniformity, so case lengths all being the same is a good thing. That said, a . 002 spread in a standard chamber/rifle/hunting bullet fired off hand or even semi supported with a shooting stick etc is plenty close enough. I just don’t recommend using a case length close to being too long.

How important is case length reloading?
In the standard calibres we have to trim because, as the case gets longer with the brass flowing forwards, the case will end up too long to actually chamber in the rifle. So, we trim the case back to a set distance to give us clearance in the chamber. Some calibres will need trimming more frequently than others.
How often should I trim my brass?
For safety, you can usually trim 4 times. When the cases are ready for their 5th trimming scrap them.
