I've used AA#7 in a lot of 10mm and it's good for me in full power loads.
it fills the case pretty much to capacity (minus bullet of course) so little chance of a double charge.
as a side note, you might want to equip your delta elite with a buffer for the
recoil spring so the slide doesn't pound your frame.
