With my faxon 20" barrel I load the 103 eldx to 2.250. The Hodgdon mag 2021, says the partition Coal is 2.150, in their barrel. It definitely will be seated deeper than the eldx, maybe down to 2.150, however of course it's easier to seat deeper than to pull it out a bit. My guess is it would be less than 2.200.
I do the 95 Nosler BT's at 2.200, they are kinda stubby too. In your pic I bet there's not much shank of the partition inside that neck...
