Gotta check the "born-on" date on those manuals …..
Since being swallowed by ATK, Speer was told to shut-up and make bullets for federal ammo. There are zero plans for a new manual in the near future. Was in Lewiston a few weeks back fishing, and stopped to see an old friend there. Unfortunately Sierra is in the same (although not as dated) boat. No money being budgeted for another manual within the next 3-5.
Hornady, and Nosler seem to be the last ones still actively shooting and producing manuals. Few companies left that aren't part of a defense contractor, or just sell to the private market as a side gig.
