Seating depth is more important than OAL as far as pressures go.

For case length to be an issue, you would have to let them get way too long before they would affect pressure as much as seating depth or bearing surface, and that would be because they can't expand at the mouth properly to release the bullet when they are fired, which will jack up pressure.

How much space the bullet takes up in the case, as well as how much of the bullet is in contact with the bore play far greater roles in pressure than cases that are over length by a couple thousandths.
