Brass different lengths

[williaada]

Getting ready to do my first reloading of my fired brass. The reloading books specs out 2.525 OAL in length. Almost, all of my fired brass measures the same as the new brass I have 2.510-2.512 OAL. Is this common or do I need to do something else?

Is it sized? You should be measuring after sizing.

It’s not uncommon for brass to go a few firings before it reaches a length that really needs to be trimmed.

It’s also not uncommon to need to trim a bunch on virgin brass.

Look at the trim length, not uncommon for it to be .010 under OAL.
Your a bit more than that but no worries, it will grow.
