Just like other rounds, book velocity has slowly decreased. One of my old Hornady manuals lists 2900 with a 200gr. Will check it again when I get home tonight.
My #10 Hornady Manual lists 2900 fps with 200g and 2600 with 250s depending on powder. Not having an in with Nosler I wonder if they keep it lower in adherence to the partition since it doesn't squeeze down as easy at the partition pressures maybe a bit more.
